* 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
This function had a bug in stable (fixed in dev) when `last` returns
npos, but the function also appears to basically be duplicating what the
next split version can do, so this just removes it and uses the single
more generic split(strview, strview) method.
* make it so that we don't set up unbound resolver when we have no resolvers provided by config
* clean up dns codepath and make it use llarp::SockAddr instead of llarp::IpAddress
- Make SockAddr endian arguments explicit
- Consolidate port-less contructors and port constructors into one with
a default port of 0.
- Add {h,n}uint128_t ctors for construction from IPv6 addrs
* rework net code for ip ranges to be cleaner
* clean up endpoint auth code
* refactor config to validate network configs before setting up endpoints
* remove buildone from path/pathbuilder.cpp so we don't spam connection attempts
- 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)
