Add helper function for synchronous execution of HCI commands at probe
stage and use this function to check firmware state of Intel Wireless
8260/8265 bluetooth devices found in many post 2016 year laptops.

Attempt to initialize FreeBSD bluetooth stack while such a device is in
bootloader mode locks the adapter hardly so it requires power on/off
cycle to restore.

This change blocks ng_ubt attachment unless operational firmware is
loaded thus preventing the lock up.

Suppose that a binary was executed from tmpfs mount, and the text
vnode was reclaimed while the binary was still running.  It is
possible during even the normal operations since tmpfs vnode'
vm_object has swap type, and no references on the vnode is held.  Also
assume that the text vnode was revived for some reason.  Then, on the
process exit or exec, unmapping of the text mapping tries to remove
the text reference from the vnode, but since it went from
recycle/instantiation cycle, there is no reference kept, and assertion
in VOP_UNSET_TEXT_CHECKED() triggers.

Fix this by keeping a use reference on the tmpfs vnode for each exec
reference.  This prevents the vnode reclamation while executable map
entry is active.

Do it by adding per-mount flag MNTK_TEXT_REFS that directs
vop_stdset_text() to add use ref on first vnode text use, and
per-vnode VI_TEXT_REF flag, to record the need on unref in
vop_stdunset_text() on last vnode text use going away.  Set
MNTK_TEXT_REFS for tmpfs mounts.

The struct is already populated on each mount (and remount). Fields are either
constant or not used by filesystem in the first place.

Some infrequently used functions use it to avoid having to allocate a new buffer
and are left alone.

The current code results in an avoidable copying single-threaded and significant
cache line bouncing multithreaded

While here deduplicate initial filling of the struct.

Revision 316342, which introduced the anticongestion feature, failed to
consider that the periodic scripts are executed by a recursive invocation of
periodic.  The recursive invocation wrongly cleaned up a temporary file that
should've been cleaned up only by the original invocation.  The result is
that if the first script that requests an anticongestion sleep runs after
the security scripts, the sleep won't happen.

Fix this bug by delaying cleanup until the end of the original invocation.

Move fast entropy source registration to the earlier
SI_SUB_RANDOM:SI_ORDER_FOURTH and move random_harvestq_prime after that.
Relocate the registration routines out of the much later randomdev module
and into random_harvestq.

This is necessary for the fast random sources to actually register before we
perform random_harvestq_prime() early in the kernel boot.

The mistake came about like this: the first attempt to commit was blocked by
a pre-commit hook due to missing SVN tags.  svn revert doesn't delete new
files, I guess.  While reapplying the fixed diff, the non-empty target file

- move allproc lock into the func, it is of no use prior to it
- the code would lock p1 and p2 while holding allproc to partially
construct it after it gets added to the list. instead we can do the
work prior to adding anything.

Code doing this is commented with a claim that these IDs are occupied by
daemons, but that's demonstrably false. To an extent the range is used by init
and kernel processes (and on sufficiently big machines it indeed is fully
populated).

On a sample box 40-way box the highest id in the range is 63. On a different one
it is 23. Just use the range.

Revision 350859 removed level of indirection that was needed for setting the
caller's `cp' pointer. dnsdecode() uses return value to indicate error or
success. It returns pointer to a buffer holding a decompressed DNS name or
NULL. The caller uses that value only to find out the result, not for accessing
the buffer.

We use the return value to propagate the new value of `cp' pointer to
the caller instead of using an output argument.
