no-op LogTrace(); print chars as ints 
- LogTrace() (and LogTraceTag, etc.) are now no-ops for release builds.
(hoping there are no side effects in trace logging!)
- renamed llarp::_Log to llarp::_log because _Log is a reserved keyword
- change logging code to implicitly convert 1-byte types (char, unsigned
char, uint8_t) to ints so that we print them as numeric values rather
than raw chars because, more often than not, printing a single char is
trying to log an 8-bit value.

Move external/ cmake bits into external/CMakeLists.txt 
- Move uvw target to external instead of llarp/CMakeLists.txt

- Add sqlite_orm headers via interface library rather than shoving it
  into the global include search path.

- Find sqlite3 as part of the sqlite_orm target deps rather than linking
  it separately.  (Also don't link it into lokinet-util, which doesn't
  appear to actually need it).

Jason Rhinelander f47e0cf7a2 Fix UB -- use after move 4 years ago
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.

make android work again 
ip packet on read error was returning an uninitialized ip packet with non zero size so it was thinking it was a valid packet.

this fixed it in an emulator at least...

Jason Rhinelander 895acc45ff EventLoop: add public wakeup() method, and call it from call() 
call(), when invoked from the logic thread, wasn't triggering a wakeup
which stalled some traffic (such as client-to-snode packets).

Fix it by triggering a wakeup on `call()`, and expose it because this is
a useful thing to be able to do.

Jason Rhinelander f8d5e106a0 Uncurse SockAddr's sockaddr* operator 
The `const sockaddr*` conversion was returning a pointer to the
sockaddr_in6, but with its family set to AF_INET, so the receiving code
would have treated interpreting the result as a sockaddr_in pointer --
but it isn't, and trying to get the IPv4 from the mis-reinterpreted
sockaddr_in6 fails; this then prevented uvw UDP binding (which uses the
sockaddr* operator) from working.

This changes it to always leave the family value at the proper value and
using the ipv6_is_mapped_ipv4 check to determine when we have (and
should return) a pointer to the sockaddr_in rather than the
sockaddr_in6.

Also fixes toString() to compare the full prefix instead of just bytes
10 and 11.

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

 4 years ago
Jeff Becker e6ac7e721d
use a std::map instead of a std::unordered_map for holding message buffers by their sequentially increasing message id. 
when retransmissions happen, they will be executed in a deterministic order by their delivery id.
this reduces the jitter from delayed message delivery on link layer as with an unordered map the order of iteration is "random",
so when we iterate all messages for retransmission we do it lowest id first (the messages queued first).
