Remove optional relay whitelist disabling
Whitelisting is now always-on for relays.  Disabling the option is never
used and is unsupported/unmaintained (it was, in theory, to allow
lokinet as a separate usage in a non-service-node relay mode, i.e. on a
completely separate network).

Confusingly, the option was enabled by the `[lokid]:enabled` config
parameter.

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

refactor dns subsystem
we want to be able to have multiple locally bound dns sockets in lokinet so
i restructured most of the dns subsystem in order to make this easier.

specifically, we have a new structure to dns subsystem:

* dns::QueryJob_Base

base type for holding a dns query and response with virtual methods
in charge of sending a reply to whoever requested.

* dns::PacketSource_Base

base type for reading and writing dns messages to and from wherever they came from

* dns::Resolver_Base

base type for filtering and handling of dns messages asynchronously.

* dns::Server

contextualized per endpoint dns object, responsible for all dns related isms.

this change hides all impelementation details of all of the dns components.
adds some more helper functions for parsing dns and dealing with OwnedBuffer.

overall dns becomes less of a pain with this new structure. probably.

oxen-logging update to handle level/type parsing exceptions 2 years ago

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).

configurable route poker
this allows you to use exit nodes without forcing routes over the interface, useful for using lokinet with an exit and selectively routing over the lokinet interface using an external socks proxy or binding to device explicitly.

* make route poker configurable, defaults to enabled but allows disabling it on runtime if desired
* add config option [network]:auto-routing to enable/disable route poker

match io loop event order on windows/apple to match linux.
on win32/apple reading packets from the interface does not count as an io operation.
manually trigger pump on win32/apple to pretend that it is an io event.
add platform quark function MaybeWakeUpperLayers on vpn::Interface to manaully wake up the other components on platforms that need that (ones on which packet io is not done via io events).
on non linux platforms, use uv_prepare_t instead of uv_check_t as the former triggers before blocking for io, instead of after. this better matches linux's order of operations in libuv.

QUIC lokinet integration refactor
Refactors how quic packets get handled: the actual tunnels now live in
tunnel.hpp's TunnelManager which holds and manages all the quic<->tcp
tunnelling.  service::Endpoint now holds a TunnelManager rather than a
quic::Server.  We only need one quic server, but we need a separate quic
client instance per outgoing quic tunnel, and TunnelManager handles all
that glue now.

Adds QUIC packet handling to get to the right tunnel code.  This
required multiplexing incoming quic packets, as follows:

Adds a very small quic tunnel packet header of 4 bytes:

    [1, SPORT, ECN] for client->server packets, where SPORT is our
    source "port" (really: just a uint16_t unique quic instance
    identifier)

or

    [2, DPORT, ECN] for server->client packets where the DPORT is the SPORT
    from above.

(This also reworks ECN bits to get properly carried over lokinet.)

We don't need a destination/source port for the server-side because
there is only ever one quic server (and we know we're going to it when
the first byte of the header is 1).

Removes the config option for quic exposing ports; a full lokinet will
simply accept anything incoming on quic and tunnel it to the requested
port on the the local endpoint IP (this handler will come in a following
commit).

Replace ConvoTags with full addresses: we need to carry the port, as
well, which the ConvoTag can't give us, so change those to more general
SockAddrs from which we can extract both the ConvoTag *and* the port.

Add a pending connection queue along with new quic-side handlers to call
when a stream becomes available (TunnelManager uses this to wire up
pending incoming conns with quic streams as streams open up).

Completely get rid of tunnel_server/tunnel_client.cpp code; it is now
moved to tunnel.hpp.

Add listen()/forget() methods in TunnelManager for setting up quic
listening sockets (for liblokinet usage).

Add open()/close() methods in TunnelManager for spinning up new quic
clients for outgoing quic connections.

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.

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
