2887a293f5 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)

If the scan fails, the code will fall through and fail as it does with Jenkins
today

r278636:

Parameterize out the amount of sleep done in each test

Set the value in each test to a different amount to avoid potential
side-effects with other instances of the test (or lingering processes) still
being present on the system

r278633:

Refactor the tests

1. `id -u` -> 0 is now only checked once; the entire test script is now skipped
   if this assertion is violated
2. De-dent whitespace, based on 1.
3. Only setup the symlink for $sleep once at the top of the script, and tear it
   down once at the bottom of the script

4fcc96bc4a Fix overflow check for multiplication:
- 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.

page and added compatibility code for old kernels. There is also audit and
Capsicum support.

A new UTIME_* constant might allow setting birthtimes in future.

afad9375d8 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.

412e06f616 sh: Make sure output suitable as shell input is also printable.
Commands like 'export -p', 'set' and 'trap', and tracing enabled via 'set
-x' generate output suitable as shell input by adding quotes as necessary.

If there are control characters other than newline or invalid UTF-8
sequences, use $'...' and \OOO to display them safely.

The resulting output is not parsable by a strict POSIX.1-2008 shell but sh
from FreeBSD 9.0 and newer and many other shells can parse it.

d41bf48327 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.
