llarp_buffer_t: rename badly named operator==
It didn't do equality, it did "does the remaining space start with the
argument" (and so the replacement in the previous commit was broken).

This renames it to avoid the confusion and restores to what it was doing
on dev.

Apply some lipstick to llarp_buffer_t
This class is cursed, but also broken under gcc-12.  Apply some lipstick
to get it moving again (but we really need to refactor this because it
is a mess).

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

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.

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).

Move destructor back to .cpp file
Having it there (even defaulted, like this) means endpoint.hpp doesn't
have to include endpoint_state.hpp (which it otherwise would need,
because of the std::unique_ptr<EndpointState> default deleter
requirements).

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.

70553c7627 Remove hopeless flush
The TriggerPump just below this is *already* going to trigger a flush,
so the extra flush call here can't do anything useful (and in
particular, it won't clear up the queue *immediately*, which is what
this code looks like it was aimed at doing).

9844d358e6 Fix packet delay creep
- Make the main PumpLL also pump hidden services, rather than using
  separate wakers in each TunEndpoint.  It seems there is some
  interactions that just one or the other is not enough.

- Eliminate TunEndpoint send queue -- it isn't needed as we can just
  send directly.

031ea7aa37 Get rid of external event loop direct wakeups
If something needs to wake up the event loop it should be using an

wakeup, expecting that PumpLL gets called on every wakeup, which isn't
true anymore.

Unleak exit mode DNS via unbound DNS trampoline on (macOS)
When we enable/disable exit mode on this restarts the unbound DNS
responder with the DNS trampoline (or restores upstream, when disabling)
to properly route DNS requests through the tunnel (because libunbound's
direct requests don't get tunneled because unbound is inside the network
extension).
