* procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.

	* Move target_signal_from_host, target_signal_to_host, and
	store_waitstatus from inftarg.c to target.c.  procfs needs them.
	* target.c: Include "wait.h" and <signal.h>.
	* target.h, infrun.c (proceed), proceed callers: Pass new code
	TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
	enums being treated as unsigned and is cleaner.
	* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
	TARGET_SIGNAL_0.
	* infcmd.c (signal_command), infrun.c (signals_info):
	Don't allow user to specify numeric equivalent of
	TARGET_SIGNAL_DEFAULT.

-LOCAL FUNCTION
-
-       procfs_wait -- emulate wait() as much as possible
-       Wait for child to do something.  Return pid of child, or -1 in case
-       of error; store status through argument pointer STATUS.
-
-
-SYNOPSIS
-
-       int procfs_wait (int pid, int *statloc)
-
-DESCRIPTION
-
-       Try to emulate wait() as much as possible.  Not sure why we can't
-       just use wait(), but it seems to have problems when applied to a
-       process being controlled with the /proc interface.
-
-NOTES
-
-       We have a race problem here with no obvious solution.  We need to let
-       the inferior run until it stops on an event of interest, which means
-       that we need to use the PIOCWSTOP ioctl.  However, we cannot use this
-       ioctl if the process is already stopped on something that is not an
-       event of interest, or the call will hang indefinitely.  Thus we first
-       use PIOCSTATUS to see if the process is not stopped.  If not, then we
-       use PIOCWSTOP.  But during the window between the two, if the process
-       stops for any reason that is not an event of interest (such as a job
-       control signal) then gdb will hang.  One possible workaround is to set
-       an alarm to wake up every minute of so and check to see if the process
-       is still running, and if so, then reissue the PIOCWSTOP.  But this is
-       a real kludge, so has not been implemented.  FIXME: investigate
-       alternatives.
-
-       FIXME:  Investigate why wait() seems to have problems with programs
-       being control by /proc routines.
