Fix some race conditions in redisplay/signal
redisplay.c, redisplay.h, signal.c: Move backtraces to internals manual. Fix some race conditions
leading to crashes due to incomplete protection of critical
sections. In signal.c, be more aggressive in catching incomplete
critical section protection -- we cannot even check for QUIT,
*EVER*, in a critical section.
