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

proper route poking (#1330)
* route poking:

* remove popen() call, replace with reading /proc/net/route for getting default route
* dynamically poke and unpoke routes on runtime

* swap intros and fix rpc endpoint for version to return what the ui expects

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.

Merge pull request #1110 from jagerman/no-abseil-optional
De-abseil, part 1: remove absl::optional

ac1486d0be Replace absl::optional with optional-lite
Step 1 of removing abseil from lokinet.

For the most part this is a drop-in replacement, but there are also a
few changes here to the JSONRPC layer that were needed to work around
current gcc 10 dev snapshot:

- JSONRPC returns a json now instead of an optional<json>.  It doesn't
  make any sense to have a json rpc call that just closes the connection
  with returning anything.  Invoked functions can return a null (default
  constructed) result now if they don't have anything to return (such a
  null value won't be added as "result").
