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.

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().

The Great Wall of Blame
This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.

Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.

f84ce61d66 Removed empty cpp files
These aren't needed: CMake already knows how to follow #includes and
rebuild when headers change as long as the headers are included
*somewhere*.  The extra .cpp files here just require building a bunch of
.cpp files with just header content that we just end up throw away
during linking (since the same things will also be compiled in whatever
other compilation units include the same headers).

b4440094b0 De-abseil, part 2: mutex, locks, (most) time
- util::Mutex is now a std::shared_timed_mutex, which is capable of
  exclusive and shared locks.

- util::Lock is still present as a std::lock_guard<util::Mutex>.

- the locking annotations are preserved, but updated to the latest
  supported by clang rather than using abseil's older/deprecated ones.

- ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into
  locks anymore (WTF abseil).

- ReleasableLock is gone.  Instead there are now some llarp::util helper
  methods to obtain unique and/or shared locks:
    - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also
      unlockable object (std::unique_lock<T>, with T inferred from
      `mutex`).
    - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e.
      "reader") lock of the mutex.
    - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be
      used to atomically lock multiple mutexes at once (returning a
      tuple of the locks).
  This are templated on the mutex which makes them a bit more flexible
  than using a concrete type: they can be used for any type of lockable
  mutex, not only util::Mutex.  (Some of the code here uses them for
  getting locks around a std::mutex).  Until C++17, using the RAII types
  is painfully verbose:

  ```C++
  // pre-C++17 - needing to figure out the mutex type here is annoying:
  std::unique_lock<util::Mutex> lock(mutex);
  // pre-C++17 and even more verbose (but at least the type isn't needed):
  std::unique_lock<decltype(mutex)> lock(mutex);
  // our compromise:
  auto lock = util::unique_lock(mutex);
  // C++17:
  std::unique_lock lock(mutex);
  ```

  All of these functions will also warn (under gcc or clang) if you
  discard the return value.  You can also do fancy things like
  `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a
  lock take over an already-locked mutex).

- metrics code is gone, which also removes a big pile of code that was
  only used by metrics:
  - llarp::util::Scheduler
  - llarp:🧵:TimerQueue
  - llarp::util::Stopwatch
