Linux route poker fixes
- don't add routes when not in exit mode
- don't call Up() from rpc code (the RouterPoker itself decides when to
  call Up())

Don't do route poking when disabled
IsEnabled() is a bit broader than just IsServiceNode, so use it instead.

Simplifications
- a `static` is less verbose and otherwise identical to an empty
  namespace for a single declaration like this.
- operator== on two optionals already does exactly what the `is_equal`
  lambda here is doing.
- formatting

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.

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

4ef25ef679 Add systemd-resolved dynamic DNS updating
Wires up systemd support to configure DNS on startup and when
enabling/disabling exit mode.

On startup (and when turning off an exit) we tell systemd-resolved to
direct .loki and .snode lookups to lokinet (leaving other DNS traffic
alone).

On exit enabling, we reconfigure it to resolve "." (i.e. the root DNS
domain) so that all lookups come into it.

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.

Route Poker changes (#1416)
If not using an exit, messing with the routing table is not good.
As such, the ability to keep track of routes we *might* want is good,
but the ability to set/unset those routes is necessary, to correspond
to enabling/disabling exit functionality.
