Add proc_waitid
proc_wait assumes that the caller always wants WEXITED, but waitid()
does not. The new proc_waitid RPC requires the caller to specify at
least one of WEXITED, WSTOPPED, or WCONTINUED.
* hurd/process.defs (proc_waitid): New RPC.
* hurd/process_reply.defs (proc_waitid): New RPC.
* hurd/process_request.defs (proc_waitid): New RPC.
* proc/proc.h (struct proc): Add p_continued field.
* proc/wait.c (WCONTINUED, WEXITED): Define if not already defined.
(S_proc_wait): Rename implementation to S_proc_waitid, and modify to
stop assuming WEXITED. Add support for WCONTINUED.
(S_proc_wait): Reimplement by just calling S_proc_waitid with an
additional WEXITED.
(proc_mark_stop): Clear p_continued.
(proc_mark_cont): Set p_continued, clear p_waited, wake any waiting
parent.
