Fix multi-field < ordering
Lots and lots of places in the code had broken < operators because they
are returning something like:

    foo < other.foo or bar < other.bar;

but this breaks both the strict weak ordering requirements that are
required for the "Compare" requirement for things like
std::map/set/priority_queue.

For example:

    a = {.foo=1, .bar=3}
    b = {.foo=3, .bar=1}

does not have an ordering over a and b (both `a < b` and `b < a` are
satisfied at the same time).

This needs to be instead something like:

    foo < other.foo or (foo == other.foo and bar < other.bar)

but that's a bit clunkier, and it is easier to use std::tie for tuple's
built-in < comparison which does the right thing:

    std::tie(foo, bar) < std::tie(other.foo, other.bar)

(Initially I noticed this in SockAddr/sockaddr_in6, but upon further
investigation this extends to the major of multi-field `operator<`'s.)

This fixes it by using std::tie (or something similar) everywhere we are
doing multi-field inequalities.

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

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.

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

97088719e0 Avoid reserved __identifiers
Identifier names with `__` in them are reserved for the implementation.
One leading underscore followed by a lower-case letter is fine though
(leading underscore followed by *upper*-case is, however, also
reserved).

f9bbc30c3d IsIPv4Bogon: constexpr array instead of a function-local static vector
The fixed-size array + not needing to do an atomic operation in the
function should allow better compiler optimization.

(And with C++17 the type and size are inferred).

bdc9c7bfa8 Move IPRange out of net.hpp; free up TruncateV6 etc.
- Move IPRange into its own net/ip_range.hpp

- Move the static net::IPPacket::TruncateV6, etc. functions to free
net::TruncateV6, etc. functions (now from net/ip.hpp instead of
net/ip_packet.hpp).

- Make net::TruncateV6 and net::ExpandV4 constexpr.

- Add IPRange::FromIPv4 factory function (to replace the iprange_ipv4
free function)

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.
