dr7ana 3451a30d0e ALPN verification
- laying the groundwork for functional client->service node connections. this requires ALPNs verification as a secondary method of identification to the remote key

dr7ana fd21eb3a00 Big fix!
- pending conns container stops them from being counted towards active conns in the interim
- un-abstracted pendingmessages vs pendingdatamessages vs pendingcontrolmessages (gross)
- fixed bootstrap fetching and storage!

Thomas Winget 27aea62994 Remove find/lookup router
We're removing the notion of find/lookup a singular RC, so this gets rid
of all functions which did that and replaces their usages with something
sensible.

Thomas Winget 9e9c1ea732 chahca nonce size is 24 bytes
Lots of code was using 32-byte nonces for xchacha20 symmetric
encryption, but this just means 8 extra bytes per packet wasted as
chacha is only using the first 24 bytes of that nonce anyway.

Changing this resulted in a lot of dead/dying code breaking, so this
commit also removes a lot of that (and comments a couple places with
TODO instead)

Also nounce -> nonce where it came up.

Thomas Winget abb2f63ec6 path control message response status changes
change path control message inner message response to take just a
string, which will be a bt-encoded response with an early key for
status.  If there is a timeout we pass a bt dict that only has that as
the status, else the response we de-onioned should have either an OK
status or some other error.

change messages to use new status key

correctly call Path::EnterState on path build response

Thomas Winget b0fb194e2c path control messages and onioning fleshed out
- control messages can be sent along a path
- the path owner onion-encrypts the "inner" message for each hop in the
  path
- relays on the path will onion the payload in both directions, such
  that the terminal relay will get the plaintext "inner" message and the
  client will get the plaintext "response" to that.
- control messages have (mostly, see below) been changed to be invokable
  either over a path or directly to a relay, as appropriate.

TODO:
  - exit messages need looked at, so they have not yet been changed for
    this
  - path transfer messages (traffic from client to client over 2 paths
    with a shared "pivot") are not yet implemented

Thomas Winget c25ced50a3 path build message handling mostly finished

dr7ana fa4471f566 {Remote,Local}RC's
- RemoteRC supplants most of the functionality throughout the code of RouterContact
- Next step will be to sort out CI issues, then see if we can get rid of either LocalRC (and therefore RouterContact entirely)

Jason Rhinelander f4f5ab0109 "Refactor" aka delete Crypto/CryptoManager
- Get rid of CryptoManager.
- Get rid of Crypto.
- Move all the Crypto instance methods to llarp::crypto functions.
  (None of them needed to be methods at all, so this is simple).
- Move sodium/ntru initialization into static initialization.
- Add llarp::csrng, which is an available llarp::CSRNG instance which is
  a bit easier than needing to construct a `CSRNG rng{};` in various
  places.
- Various related small simplifications/cleanups.

dr7ana 511c20cdb6 Message handling methods
- `::handle_message` is transposed; Rather than the message calling the method and taking a reference to the router, the router should have a handle_message method and take a reference to the message
- `::EndcodeBuffer` takes a string reference, to which the result of `::bt_encode()` is assigned

Replace duration/timestamp formats with functions
We're defining formats for std::chrono types, which feels wrong (because
fmt itself also has these), so just replace them with functions:

short_time_from_now(...) gives a short "in 14m12s" or "5.123s ago" time
span relative to now, given a time point.  Precision gets reduced for
larger deviations from now (e.g. "4h12m ago").

ToString(Duration_t) gives a string such as "-3h22m02.123s" for a
duration.

changeset for windows port
* wintun vpn platform for windows
* bundle config snippets into nsis installer for exit node, keyfile persisting, reduced hops mode.
* use wintun for vpn platform
* isolate all windows platform specific code into their own compilation units and libraries
* split up internal libraries into more specific components
* rename liblokinet.a target to liblokinet-amalgum.a to elimiate ambiguity with liblokinet.so
* DNS platform for win32
* rename llarp/ev/ev_libuv.{c,h}pp to llarp/ev/libuv.{c,h}pp as the old name was idiotic
* split up net platform into win32 and posix specific compilation units
* rename lokinet_init.c to easter_eggs.cpp as that is what they are for and it does not need to be a c compilation target
* add cmake option STRIP_SYMBOLS for seperating out debug symbols for windows builds
* intercept dns traffic on all interfaces on windows using windivert and feed it into lokinet

Replace logging with oxen-logger
Replaces custom logging system with spdlog-based oxen logging.  This
commit mainly replaces the backend logging with the spdlog-based system,
but doesn't (yet) convert all the existing LogWarn, etc. to use the new
format-based logging.

New logging statements will look like:

    llarp::log::warning(cat, "blah: {}", val);

where `cat` should be set up in each .cpp or cluster of .cpp files, as
described in the oxen-logging README.

As part of spdlog we get fmt, which gives us nice format strings, where
are applied generously in this commit.

Making types printable now requires two steps:
- add a ToString() method
- add this specialization:

      template <>
      constexpr inline bool llarp::IsToStringFormattable<llarp::Whatever> = true;

This will then allow the type to be printed as a "{}" value in a
fmt::format string.  This is applied to all our printable types here,
and all of the `operator<<` are removed.

This commit also:
- replaces various uses of `operator<<` to ToString()
- replaces various uses of std::stringstream with either fmt::format or
  plain std::string
- Rename some to_string and toString() methods to ToString() for
  consistency (and to work with fmt)
- Replace `stringify(...)` and `make_exception` usage with fmt::format
  (and remove stringify/make_exception from util/str.hpp).

Jason Rhinelander 0fe7153f6e Fix client latency bug; De-shared_ptr IHopHandler queues
- Replace m_FlushWakeup with a call to the router's god mode pump
  method.  m_FlushWakeup apparently isn't enough to get things out, and
  we can end up with incoming packets that don't get properly handled
  right away without it.

- The shared_ptr around the ihophandler queues isn't needed and is just
  adding a layer of obfuscation; instead just exchange the list directly
  into the lambda.

- Use std::exchange rather than swap

- A couple other small code cleanups.

Jason Rhinelander 031ea7aa37 Get rid of external event loop direct wakeups
If something needs to wake up the event loop it should be using an
async, as we are now with PumpLL(); but we had various code triggering a
wakeup, expecting that PumpLL gets called on every wakeup, which isn't
true anymore.
