lib: tevent: make TEVENT_SIG_INCREMENT atomic.
On arm platforms incrementing a variable is not
an atomic operation, so may be interrupted by
signal processing (if a signal interrupts another
signal handler).
Use compiler built-ins to make this atomic.
__sync_fetch_and_add() works on gcc, llvm,
IBM xlC on AIX, and Intel icc (10.1 and
above).
atomic_add_32() works on Oracle Solaris.
Based on an inital patch from kamei@osstech.co.jp.
