6556af1100 force_send_savestate is global again 
We cannot send a savestate to only one player, as sending a savestate is
a synchronization event invalidating all prior input.

e7ce01ad3b More renaming 
Now that remote_input_state isn't always remote, it should just be
called real_input_state (and is).

1245d1b5dd Better netplay input simulation 
In resimulation mode, we only copy the buttons. The reason for this
is nonobvious:

If we resimulated nothing, then the /duration/ with which any input
was pressed would be approximately correct, since the original
simulation came in as the input came in, but the /number of times/
the input was pressed would be wrong, as there would be an
advancing wavefront of real data overtaking the simulated data
(which is really just real data offset by some frames).

That's acceptable for arrows in most situations, since the amount
you move is tied to the duration, but unacceptable for buttons,
which will seem to jerkily be pressed numerous times with those
wavefronts.

42da0a0184 NAT traversal in Netplay 
For the time being, if NAT traversal is successful it simply announces
it as an OSD message. In the future it will be used to inform a
matchmaking server of the public port.

This patch also included minor fixes to the NAT traversal implementation
to make the select it demands actually doable.

6c15c0de3d Support for architecture-dependence serialization quirks in Netplay 
As well as the implementation magic, we now send a platform magic in our
connection header. If the core reports platform dependence and the
platform magic differs relevantly, the connection will be refused.

Since netplay_send_info (client handshake) and netplay_get_info (server
handshake) were practically identical, they've also been merged into a
single netplay_handshake.

immediately blocking to waiting for a connection while allowing the game
to run, like spectator mode.
