MFC r317845-r317846
r317845:
Provide a freebsd32 implementation of sigqueue()
The previous misuse of sys_sigqueue() was sending random register or
stack garbage to 64-bit targets. The freebsd32 implementation preserves
the sival_int member of value when signaling a 64-bit process.
Document the mixed ABI implementation of union sigval and the
incompability of sival_ptr with pointer integrity schemes.
