crs 014578b875 Fixed a serious flaw in wrapper for posix condition variable wait ...

function.  Because synergy doesn't use posix cancellation, it
cannot wake up a thread waiting on a condition variable.  So
the wrapper would wake up periodically to test if the thread was
cancelled (according to synergy's cancellation state) then go
back to waiting.  Well the condition could be signalled while
we're testing and be lost and we'd never return from the wait.
So now we wake up after a maximum timeout and return to the
caller.  The caller must check for this spurious wakeup but all
callers should do this anyway so we're okay there.
