Implement one mutex per cuse(3) server instance which also cover the
clients belonging to the given server instance.
This should significantly reduce the mutex congestion inside the
cuse(3) kernel module when multiple servers are in use.

about converting existing audio channel structures into arrays.
The main audio mixer is provided by the first PCM instance.
The non-first audio instances may only have a software mixer for PCM playback.

taskqgroup initialization was broken into two steps:
1. allocate the taskqgroup structure, at SI_SUB_TASKQ;
2. initialize taskqueues, start taskqueue threads, enqueue "binder"
tasks to bind threads to specific CPUs, at SI_SUB_SMP.
Step 2 tries to handle the case where tasks have already been attached
to a queue, by migrating them to their intended queue. In particular,
tasks can't be enqueued before step 2 has completed. This breaks NFS
mountroot on systems using an iflib-based driver when EARLY_AP_STARTUP
is not defined, since mountroot happens before SI_SUB_SMP in this case.
Simplify initialization: do all initialization except for CPU binding at
SI_SUB_TASKQ. This means that until CPU binding is completed, group
tasks may be executed on a CPU other than that to which they were bound,
but this should not be a problem for existing users of the taskqgroup
KPIs.

As a followup to the use of login.conf environment vars (other than PATH) in
cron, this patch adds PATH (and HOME) to the list of login.conf settings
respected.
The new logic is as follows:
1. SHELL is always _PATH_BSHELL unless explicitly overridden in the crontab
file itself; no other settings are respected. This is unchanged.
2. PATH is taken from the first of: crontab file, login.conf, _PATH_DEFPATH
3. HOME is taken from the first of: crontab file, login.conf, passwd entry,
unset
4. The current directory for invoking the command is taken from the crontab
file's value of HOME (existing behavior), or the passwd entry, but not
anywhere else (so it might not equal HOME if that was set in login.conf).

debug was declared extern, but debug_file was not; correct this and define
debug_file in main.c (as debug is) to fix the -fno-common build.

As described in the comment, gdb relies on some of the linker magic that
happens with -fcommon. I suspect the life expectancy of gdb-in-base is low
enough that this isn't worth spending much time addressing, especially given
the vintage. Hit it with the -fcommon hammer so that it continues to just
work.

Incompatibility between i386 and amd64 evdev ABIs was caused by presence of

Many rtsock tests verify the ordering of the kernel messages for the
particular event. In order to avoid flaky tests due to the other tests
running, switch all tests to use personal vnet-enabled jails.
This removes all clashes on the IP addresses and brings back the ability
to run these tests simultaneously.

The efi console init is avoided since conin setup was moved to probe.
In case the console is re-initialized, we need to pick up colors
from environment.
This option is intended to aid development, to allow building with user malloc.
The use case would be to build userboot & test with libc (or other) malloc and
use extra malloc debug features.

telnetd will #define extern and then include ext.h to allocate storage for
all of these extern'd vars; however, two of them are actually defined in
libtelnet instead. Instead of doing an #ifdef extern dance around those
function pointers, just add an EXTERN macro to make it easier to
differentiate by sight which ones will get allocated in globals.c and which
ones are defined elsewhere.
