Apple OS interface cleanup & refactoring
- Add a C callback interface (context_wrapper.h) between lokinet and the
  objective-C code so that:
  - we can use objective-C (rather than objective-C++), which seems more
    likely to be supported by Apple into the future;
  - we minimize the amount of code that needs to be aware of the Apple
    APIs.
  - this replaces apple logger objective c++ implementation with a plain
    c++ implementation that takes a very simple C callback (provided
    from the obj-c code) to actually make the call to NSLog.

- Add various documentation to the code of what is going on.

- Send all DNS traffic to the primary IP on the tun interface.  The
  match prefixes simply don't work as advertised, and have weird shit
  (like even if you get it working for some domains, "instagram.com"
  still doesn't because of god-knows-what Apple internal politics).

- Drop the dns proxy code as we don't need it anymore.

- Don't use 9.9.9.9 for default DNS.  (We might consider the unfiltered
  9.9.9.10 as an alternative default, but if we do it should be a global
  lokinet change rather than a Mac-specific change).

- Parse a lokinet.ini in the data directory, if it exists.  (Since we
  are sandboxed, it is an app-specific "home" directory so is probably
  buried god knows where, but at least the GUI ought to be able to get
  it to let users add things to it).

- This commit also adds a swift version of the PacketTunnelProvider
  glue, which ought to work in theory, but the *tooling* for cmake is so
  underdeveloped that I couldn't find any way to actually get the damn
  thing working.  So I'm committing it here anyway (and will revert it
  away in the next commit) in case we someday want to switch to it.
