various: general adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Chase malloc() change by removing lg_chunk malloc_conf settings. In jemalloc 5, there are no longer chunks, and as configured on FreeBSD (the "retain" option defaults to false), the mmap() requests are precisely sized for the specific needs, which means the virtual memory overhead should be lower for small applications.

Add a new exit-timeout option to watchdogd. Watchdogd currently disables the watchdog when it exits, such as during rc.shutdown processing. That leaves the system vulnerable to getting hung or deadlocked during the shutdown part of a reboot. For embedded systems it's especially important that the hardware watchdog always be active. It can also be useful for servers that are administered remotely. The new -x <seconds> option tells watchdogd to program the watchdog with the given timeout just before exiting. The -x value can be longer or shorter than the -t normal time value, to allow for various exceptional conditions at shutdown such as allowing extra time for buffer flushing. The exit value is also used internally in the "failsafe" handling (which used to just disable the watchdog), on the theory that if you're using this option, "safe" means having the watchdog always running, not disabled. The default is still to disable the watchdog on exit if -x is not specified. Differential Revision: https://reviews.freebsd.org/D2556 (timed out)

Default to use 10 seconds as nap interval instead of 1. Previously, we have a nap interval of 1 second while we have a timeout of 128 seconds by default, which could be an overkill, and for some hardware the patting action may be expensive. Note that the choice of nap interval is still arbitrary. We preferred a safe value where even when the system is very heavily loaded, the watchdog should not shoot the system down if it's not really hung. According to the manual page of Linux's watchdog daemon, the nap interval time of theirs is 10 seconds, which seems to be a reasonable value -- according to Intel documentation AP-725 (Document Number: 292273-001), ICH5's maximum timeout is about 37.5 seconds, which the ichwd(4) driver would set when we requested 128 seconds (although it should probably feed back this as an error and do not set the timeout). Since that's the shortest maximum value, 10 seconds seems to be a right choice for us too. Discussed with: alfred MFC after: 1 month

Support the following in watchdogged: - Support to utilize the new additions to watchdog(4). - Support to warn if a watchdog script runs for too long. - Support for "dry run" where we do not actually arm the watchdog, but only report on our timing.

Reduce watchdogd's memory footprint when running daemonized. This uses the recently-added jemalloc(3) feature of setting the lg_chunk tuning option to zero to request that memory be allocated in the smallest chunks possible. Without this option, the default is to initally map 8MB, and then the mlockall() call wires that entire allocation even though the program only uses a few Kbytes of it at runtime.
