Thomas Winget 4c630e0437 Large collection of changes to make android work
- Previous android java and jni code updated to work, but with much love
  still needed to make it work nicely, e.g. handling when the VPN is
  turned off.

- DNS handling refactored to allow android to intercept and handle DNS
  requests as we can't set the system DNS to use a high port
  (and apparently Chrome ignores system DNS settings anyway)

- add packet router structure to allow separate handling of specific
  intercepted traffic, e.g. UDP traffic to port 53 gets handled by our
  DNS handler rather than being naively forwarded as exit traffic.

- For now, android lokinet is exit-only and hard-coded to use exit.loki
  as its exit.  The exit will be configurable before release, but
  allowing to not use exit-only mode is more of a challenge.

- some old gitignore remnants which were matching to things we don't
  want them to (and are no longer relevant) removed

- some minor changes to CI configuration

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.

attempt fix for libunbound on win32
* run unbound stuff in another thread because LOL windows
* because unbound runs in another thread callbacks for libunbound need to be wrapped in a deferred call so they are done in the logic thread
* bump sqlite3 dep because it's gone, repin hash.

Thomas Winget b875d40491 restructure how upstream dns replies are handled
llarp::dns::Message does not fully support DNS packets,
so converting the upstream response to one will not work
for all query types.  Also it is kinda silly to begin with,
as the upstream reply is already a network packet, ready to go.
