8b45db8ee2 date(1): Make -r behave like GNU's version when the option can not be
interpreted as a number, which checks the file's modification time and
use that as the date/time value.

This improves compatibility with GNU coreutils's version of time(1).

c633f8dc04 cp: Remove fts sorting.
In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.

The sorting reorders multiple arguments passed to cp, which may be
undesirable.

Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().

NetBSD removed the sorting in 2009.

On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).

chmod, chflags, chgrp, chmod and chown now affect symlinks in -R mode as
defined in symlink(7); previously symlinks were silently ignored.

I added the interactive check in r208881 to be safe, but in actual use
(scripts in set -m mode) passing along SIGINT seems best.

a59f817491 sh: Fix the trap builtin to be POSIX-compliant for 'trap exit SIG' and 'trap n n...'.
The parser considered 'trap exit INT' to reset the default for both EXIT and
INT. This beahvior is not POSIX compliant. This was avoided if a value was
specified for 'exit', but then disallows exiting with the signal received. A
possible workaround is using ' exit'.

However POSIX does allow this type of behavior if the parameters are all
integers. Fix the handling for this and clarify its support in the manpage
since it is specifically allowed by POSIX.

c2290ff6b8 Use 24h timestamps in the ps(1) STARTED column
The previous 12h AM/PM format was perplexing as it didn't follow the
locale of the user and was a minor annoyance to FreeBSD users coming
from Linux. Additionally, the man page was incorrect about the strftime
format.

There are three time formats that may be displayed in the STARTED
column depending on the age of the process. Below is an example.

For a process started at 14:30 on Monday 16 March 2015, the following
formats may be used:

14:30 for process < 24h old (24h Timestamp)
Mon14 for process > 24h, < 1 week old (Weekday Hour)
16Mar15 for process > 1 week old (Day Month Year)

- Add special test to detect the case of -1 * INTMAX_MIN
- Protect against elimination of the test division by the optimizer

Garrett Cooper noticed that the overflow checks were incomplete, and Bruce
Evans suggested the use of the "volatile" qualifier to counter the effect
of the undefined behaviour, when the prior multiplication caused overflow,
and he also suggested improvements to the comments.

7a37b5fc17 Add a ${CP} alias for copying files in the build.
Some users build FreeBSD as non-root in Perforce workspaces.  By default,
Perforce sets files read-only unless they're explicitly being edited.
As a result, the -f argument must be used to cp in order to override the
read-only flag when copying source files to object directories.  Bare use of
'cp' should be avoided in the future.

Update all current users of 'cp' in the src tree.

6ddcc23386 Add facility to stop all userspace processes. The supposed use of the
feature is to quisce the system before suspend.

Stop is implemented by reusing the thread_single(9) with the special
mode SINGLE_ALLPROC.  SINGLE_ALLPROC differs from the existing
single-threading modes by allowing (requiring) caller to operate on
other process.  Interruptible sleeps for !TDF_SBDRY threads are
suspended like SIGSTOP does it, instead of aborting the sleep, like
SINGLE_NO_EXIT, to avoid spurious EINTRs on resume.

Provide debugging sysctl debug.stop_all_proc, which causes total stop
and suspends syncer, while waiting for variable reset for resume.  It
is used for debugging; should be removed after the real use of the
interface is added.
