7df966457d Add an option to building PS, so that the upages are explicitly paged in only 
for users who are root, or in group wheel.  This is useful on large timesharing
systems where a PS command can cause the system to grind to a halt.  The
ability to get the information isn't diminished for those who really need the
additional detail (administrators.)  Normal users won't see any difference unless
the processes are swapped out.  The "really get it mode" is invoked by the
use of an additional flag in the command string "-f".  New/old behavior is
selectable with a compile option.

Add an option to the way UFS works dependent on the SUID bit of directories
This changes makes things a whole lot simpler on systems running as
fileservers for PCs and MACS. to enable the new code you must
1/ enable option SUIDDIR on the kernel.
2/ mount the filesystem with option suiddir.
hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.

a7f8a3e8cf Fixed some type and value mismatches. setsignal() returned a bogusly 
cast value that was always ignored.  Rev.1.9 of trap.c made this
more bogus by returning a semantically different value after calling
siginterrupt().  Avoid these problems by not returning a value.

ae5a7dcd2a 1) Fix longstanding bug: 
trap 'echo xxx' 1 2 3 15
	read x
is not interrupted by ^C (due to restartable read syscall) and must be
interrupted per POSIX
Worse case:
	read -t 5 x
hangs forever after ^C pressed (supposed to timeout after 5 secs)
Fixed by adding siginterrupt(signo, 1) after catch handler installed

2) Do not reinstall sighandler immediately after it is called,
BSD do it for us

a8fc4c3cfd Add the '-t timeout' option to the 'read' builtin. This allows the 
'read' command to return an error if the user fails to supply any
input withink a given time period.  The behaviour of this option is
similar to that of the like-named option in ksh93.

d97633dae5 Pad the input buffer whenever sync is used, not just if the noerror flag 
is also set.
Change osync to not to tack on an empty block if the input buffer is null,
    or an even multiple of the blocksize.
Also change osync to pad the output with nulls/spaces depending whether
   this is a block-oriented conversion or not (same as sync).
