Retail saved tracker stats to the local pilot file after read, however
the newer pilot file code doesn't work the same way. This adds the
ability to properly update the pilot file with multiplayer stats from
the tracker during login.
NOTE: This will always overwrite multi stats in the pilot file with
the stats from the tracker!
A bit overkill for some of this but just covering the bases.
* fix issues with in-game join
* fix multi messaging and multi pause screen
* make sure maintenance stuff (pings, voice, file xfer, etc.) isn't
affected by pausing or time compression
* add new popup type to handle mission/table validation
* fix error handling when popup gets canceled
* use bool and get rid of Int3()
* use proper Game_mode check to test for standalone
These issues caused the stats packet to keep growing during
every conversion between network and game structs causing
memory issues and data corruption. These bugs were hidden by
the fact that stats packets were discarded by the server due
to another bug.
The standalone did not initialize SDL and so did not receive the quit
signal when it was sent SIGTERM or SIGINT. This fixes that by making the
standalone server just use the normal os initialization code.
Also includes some other code cleanup and some more logging to make it
more apparent in the log what is currently happening at standalone
startup.
