fix route poking via rpc:
* immediately poke routes when we are told to use an exit so that packets get pushed which makes an exit path happen

Rename isRouter -> isSNode
The isRouter wording was quite confusing, especially in a call such as:

    router->Configure(config, opts.isRouter, nodedb)

Thomas Winget 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.

Jason Rhinelander 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).

Jason Rhinelander 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

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

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.

Refactor NotifyRouterEvent() to forward args, event code cleanup
This template-ifies Router::NotifyRouterEvent() up so that it accepts
the arguments to instantiate the specified event type, forwarding them
to std::make_unique. This would allow (in the future) the function to
no-op the call and avoid memory allocation. It also slightly reduces
the amount of code required to fire an event.

This commit also simplifies some of the RouterEvent code to reduce
redundancy.

Thomas Winget 8d03e6dd3c more router hive stuff, read below the fold
Router now has a hive pointer if LOKINET_HIVE is set.
llarp::Context has a method InjectHive to give Router the pointer.
Router has a method NotifyRouterEvent which does:
  - when LOKINET_HIVE is set, passes the event to RouterHive
  - else when LOKINET_DEBUG is set, prints the event at a low log level
  - else NOP

Thomas Winget 38fd0552d3 Adds Link-Relay Status Messages
Success case:
  - the path endpoint creates and sends a LR_StatusMessage upon
    successful path creation

Failure case:
  - an intermediate hop creates and sends a LR_StatusMessage upon
    failure to forward the path to the next hop for any reason

Both cases:
  - transit hops receive LR_StatusMessages and add a frame
    to them reflecting their "status" with respect to that path
  - the path creator receives LR_StatusMessages and decrypts/parses
    the LR_StatusRecord frames from the path hops.  If all is good,
    the Path does as it would when receiving a PathConfirmMessage.
    If not, the Path marks the new path as failed.

LR_StatusMessage is now used/sent in place of PathConfirmMessage

Thomas Winget baf8019fe5 Refactor Router code into more classes
This commit refactors functionality from the Router class into separate,
dedicated classes.
There are a few behavior changes that came as a result of discussion on
what the correct behavior should be.
In addition, many things Router was previously doing can now be provided
callback functions to alert the calling point when the asynchronous
action completes, successfully or otherwise.
