poll() but there was a race condition where the thread trying
to unblock poll() could send the signal before the polling
thread had entered poll(). Now using a pipe and polling on
that and the client's sockets, and just writing a byte into
the pipe to unblock poll. This persists until the next call
to poll() so we might force poll() to return once unnecessarily
but that's not a problem. This change makes the BSD code
similar to the winsock code, which uses a winsock event instead
of a pipe.
and the platform specific implementations to lib/platform.
Added an lib/arch method to query the platform's native wide
character encoding and changed CUnicode to use it. All
platform dependent code is now in lib/arch, lib/platform,
and the programs under cmd. Also added more documentation.
lib/arch. This should make porting easier. Will probably
continue to refactor a little more, moving platform dependent
event handling stuff into lib/platform.
