Implement waitid(2) which is now part of POSIX and used by mozilla.
This includes a change of siginfo_r which is technically an ABI break but
this should have no real-world impact since the members involved are
never touched by the kernel.

Implement the WCONTINUED flag to the wait(2) family of syscalls and the
associated WIFCONTINUED macro as per 1003.1-2001. Adapted from FreeBSD.
A minor amount of trickiness is involved here. The value for WCONTINUED
is chosen in such a way that _WSTATUS(_WCONTINUED) == _WSTOPPED and the
WIFSTOPPED macro has been modified such that WIFSTOPPED(_WCONTINUED) !=
_WSTOPPED. This means we don't need to add an extra check to the
WIFSIGNALED and WIFSTOPPED macros. deraadt@ OK.
