9950adf472 Remove unneeded split(str, char) method
This function had a bug in stable (fixed in dev) when `last` returns
npos, but the function also appears to basically be duplicating what the
next split version can do, so this just removes it and uses the single
more generic split(strview, strview) method.

no-op LogTrace(); print chars as ints
- LogTrace() (and LogTraceTag, etc.) are now no-ops for release builds.
(hoping there are no side effects in trace logging!)
- renamed llarp::_Log to llarp::_log because _Log is a reserved keyword
- change logging code to implicitly convert 1-byte types (char, unsigned
char, uint8_t) to ints so that we print them as numeric values rather
than raw chars because, more often than not, printing a single char is
trying to log an 8-bit value.

7caa87862e standardize include format and pragma once
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once

Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein.  Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`

The above does not include system/os headers.

ccc7b5c9e9 Merge Logic functions into EventLoop
loop->call(...) is similar to the old logic->Call(...), but is smart
about the current thread: if called from within the event loop it simply
runs the argument directly, otherwise it queues it.

Similarly most of the other event loop calls are also now thread-aware:
for example, `call_later(...)` can queue the job directly when called if
in the event loop rather than having to double-queue through the even
loop (once to call, then inside the call to initiate the time).

5b555ee5aa Replace libuv with uvw & related refactoring
- removes all the llarp_ev_* functions, replacing with methods/classes/functions in the llarp
  namespace.
- banish ev/ev.h to the void
- Passes various things by const lvalue ref, especially shared_ptr's that don't need to be copied
  (to avoid an atomic refcount increment/decrement).
- Add a llarp::UDPHandle abstract class for UDP handling
- Removes the UDP tick handler; code that needs tick can just do a separate handler on the event
  loop outside the UDP socket.
- Adds an "OwnedBuffer" which owns its own memory but is implicitly convertible to a llarp_buffer_t.
  This is mostly needed to take over ownership of buffers from uvw without copying them as,
  currently, uvw does its own allocation (pending some open upstream issues/PRs).
- Logic:
  - add `make_caller`/`call_forever`/`call_every` utility functions to abstract Call wrapping and
    dependent timed tasks.
  - Add inLogicThread() so that code can tell its inside the logic thread (typically for
    debugging assertions).
  - get rid of janky integer returns and dealing with cancellations on call_later: the other methods
    added here and the event loop code remove the need for them.
- Event loop:
  - redo everything with uvw instead of libuv
  - rename EventLoopWakeup::Wakeup to EventLoopWakeup::Trigger to better reflect what it does.
  - add EventLoopRepeater for repeated events, and replace the code that reschedules itself every
    time it is called with a repeater.
  - Split up `EventLoop::run()` into a non-virtual base method and abstract `run_loop()` methods;
    the base method does a couple extra setup/teardown things that don't need to be in the derived class.
  - udp_listen is replaced with ev->udp(...) which returns a new UDPHandle object rather that
    needing gross C-style-but-not-actually-C-compatible structs.
  - Remove unused register_poll_fd_(un)readable
  - Use shared_ptr for EventLoopWakeup rather than returning a raw pointer; uvw lets us not have to
    worry about having the event loop class maintain ownership of it.
  - Add factory EventLoop::create() function to create a default (uvw-based) event loop (previously
    this was one of the llarp_ev_blahblah unnamespaced functions).
  - ev_libuv: this is mostly rewritten; all of the glue code/structs, in particular, are gone as
    they are no longer needed with uvw.
- DNS:
  - Rename DnsHandler to DnsInterceptor to better describe what it does (this is the code that
    intercepts all DNS to the tun IP range for Android).
- endpoint:
  - remove unused "isolated network" code
  - remove distinct (but actually always the same) variables for router/endpoint logic objects
- llarp_buffer_t
  - make constructors type-safe against being called with points to non-size-1 values
- tun packet reading:
  - read all available packets off the device/file descriptor; previously we were reading one packet
    at a time then returning to the event loop to poll again.
  - ReadNextPacket() now returns a 0-size packet if the read would block (so that we can implement
    the previous point).
  - ReadNextPacket() now throws on I/O error
- Miscellaneous code cleanups/simplifications

Some Windows fixes (#1415)
* Should fix some windows service issues

* fix return condition inversion

* Add some Trace level logging

also make the logger actually respect the log level you set.

* event loop should not queue things to itself...

at present, logic thread queue continues until it is empty, so
queueing things onto itself is just wasteful.

* call_later(foreach thing) is better than foreach thing (call later)

also if you already queued those things but they have not happened yet,
there is no sense to queue them to happen again.

* do not queue read on write finish, only on read finish

* failure to start DNS server should be proper startup failure.

without the DNS server working lokinet is...kinda pointless, right?

* format

* don't queue stuff to logic thread if in logic thread
the thing that clears the queue...clears it.  So you're just delaying and adding overhead.

* windows unbound thread sleep instead of just busy-waiting

also clang-format decided I can't have a blank line for some reason...

* fix unbound async worker on windows

Config file improvements (#1397)
* Config file API/comment improvements

API improvements:
=================

Make the config API use position-independent tag parameters (Required,
Default{123}, MultiValue) rather than a sequence of bools with
overloads.  For example, instead of:

    conf.defineOption<int>("a", "b", false, true, 123, [] { ... });

you now write:

    conf.defineOption<int>("a", "b", MultiValue, Default{123}, [] { ... });

The tags are:
- Required
- MultiValue
- Default{value}
plus new abilities (see below):
- Hidden
- RelayOnly
- ClientOnly
- Comment{"line1", "line2", "line3"}

Made option definition more powerful:
=====================================

- `Hidden` allows you to define an option that won't show up in the
  generated config file if it isn't set.

- `RelayOnly`/`ClientOnly` sets up an option that is only accepted and
  only shows up for relay or client configs.  (If neither is specified
  the option shows up in both modes).

- `Comment{...}` lets the option comments be specified as part of the
  defineOption.

Comment improvements
====================

- Rewrote comments for various options to expand on details.
- Inlined all the comments with the option definitions.
- Several options that were missing comments got comments added.
- Made various options for deprecated and or internal options hidden by
  default so that they don't show up in a default config file.
- show the section comment (but not option comments) *after* the
  [section] tag instead of before it as it makes more sense that way
  (particularly for the [bind] section which has a new long comment to
  describe how it works).

Disable profiling by default
============================

We had this weird state where we use and store profiling by default but
never *load* it when starting up.  This commit makes us just not use
profiling at all unless explicitly enabled.

Other misc changes:
===================

- change default worker threads to 0 (= num cpus) instead of 1, and fix
  it to allow 0.
- Actually apply worker-threads option
- fixed default data-dir value erroneously having quotes around it
- reordered ifname/ifaddr/mapaddr (was previously mapaddr/ifaddr/ifname)
  as mapaddr is a sort of specialization of ifaddr and so makes more
  sense to come after it (particularly because it now references ifaddr
  in its help message).
- removed peer-stats option (since we always require it for relays and
  never use it for clients)
- removed router profiles filename option (this doesn't need to be
  configurable)
- removed defunct `service-node-seed` option
- Change default logging output file to "" (which means stdout), and
  also made "-" work for stdout.

* Router hive compilation fixes

* Comments for SNApp SRV settings in ini file

* Add extra blank line after section comments

* Better deprecated option handling

Allow {client,relay}-only options in {relay,client} configs to be
specified as implicitly deprecated options: they warn, and don't set
anything.

Add an explicit `Deprecated` tag and move deprecated option handling
into definition.cpp.

* Move backwards compat options into section definitions

Keep the "addBackwardsCompatibleConfigOptions" only for options in
sections that no longer exist.

* Fix INI parsing issues & C++17-ify

- don't allow inline comments because it seems they aren't allowed in
ini formats in general, and is going to cause problems if there is a
comment character in a value (e.g. an exit auth string).  Additionally
it was breaking on a line such as:

    # some comment; see?

because it was treating only `; see?` as the comment and then producing
an error message about the rest of the line being invalid.

- make section parsing stricter: the `[` and `]` have to be at the
beginning at end of the line now (after stripping whitespace).

- Move whitespace stripping to the top since everything in here does it.

- chop off string_view suffix/prefix rather than maintaining position
values

- fix potential infinite loop/segfault when given a line such as `]foo[`

* Make config parsing failure fatal

Load() LogError's and returns false on failure, so we weren't aborting
on config file errors.

* Formatting: allow `{}` for empty functions/structs

Instead of using two lines when empty:

    {
    }

* Make default dns bind 127.0.0.1 on non-Linux

* Don't show empty section; fix tests

We can conceivably have sections that only make sense for clients or
relays, and so want to completely omit that section if we have no
options for the type of config being generated.

Also fixes missing empty lines between tests.

* fully rwemove tag_lookup_job

* replace lns cache with DecayingHashTable

* check for lns name validity against the following rules:

* not localhost.loki, loki.loki, or snode.loki

* if it contains no dash then max 32 characters long, not including the .loki tld (and also assuming a leading subdomain has been stripped)

* These are from general DNS requirements, and also enforced in
registrations:

* Must be all [A-Za-z0-9-]. (A-Z will be lower-cased by the RPC call).

* cannot start or end with a -

* max 63 characters long if it does contain a dash

* cannot contain -- in the third and fourth characters unless it starts with xn--

* handle timeout in name lookup job by calling the right handler with std::nullopt

SRV Record handling for introsets (#1331)
* update loki-mq submodule for tuple support

* srv record reply implementation

still need to encode srv records into intro sets / router contacts
as well as decode from them and match against queried service.proto

* inverted condition fix in config code

* SRV record struct (de-)serialization for intro sets

* parsing and using srv records from config (for/in introsets)

* adopt str utils from core and use for srv parsing

* changes to repeat requests

no longer drop repeat requests on the floor, but do not make
an *actual* request for them if one is in progress.

do not call reply hook for each reply for a request, as
each userland request is actually made into several lokinet
requests and this would result in duplicate replies.

* fetch SRVs from introsets for .loki

* make format

* dns and srv fixes, srv appears to be working
