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).

plug memory leak in outbound message queue.
sometimes we use rxid in our pathid so we need to clear those queues too.
if we don't it'll leak from never clearing those queues.

prevent crash by removing duplicate logic (#1515)
when a path expires or fails or something causes its lifecycle to end we have cleanup
logic that handles clean up for it. this removes a code path that was crashing that
is duplicated elsewhere and is thus probably safe to bin. yolo.

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.

LNS (#1342)
* initial relay side lns

* fix typo

* add reserved names and refactor test for dns

* lns name decryption

* all wired up (allegedly)

* refact to use service::EncryptedName for LNS responses to include nonce with ciphertext

* 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

ebd2142114 Don't use std::optional::value() because f u macos
This replaces all use of std::optional's `opt.value()` with `*opt`
because macOS is great and the ghost of Steve Jobs says that actually
supporting std::optional's value() method is not for chumps before macOS
10.14.  So don't use it because Apple is great.

Pretty much all of our use of it actually is done better with operator*
anyway (since operator* doesn't do a check that the optional has a
value).

Also replaced *most* of the `has_value()` calls with direct bool
context, except for one in the config section which looked really
confusing at a glance without a has_value().
