ATF tests have a default WARNS of 0, unlike other usermode programs. This
change is technically a noop, but it documents that the msun tests don't
work with any warnings enabled, at least not on all architectures.

Some SIMs may not abort them implicitly, that either fail the LUN disable
request or just make us wait for those CCBs forever. With this change
I can successfully disable LUNs on mpt(4). For isp(4), which aborts them
implicitly, this change should be irrelevant.

TFTP/MFSRoot booting via PXE. For the TFTP_LOADER case, go ahead and
fire off the old bootp() request to ensure that whatever is missing is
populated.

The parsed internal representation of words consists of a byte string with a
list of nodes (commands in command substitution). Each unescaped CTLBACKQ or
CTLBACKQ | CTLQUOTE byte corresponds to an entry in the list.
If param in ${param#%##%%word} is not set, the word is not expanded (in a
deviation of POSIX shared with other ash variants and ksh93). Erroneously,
the pointer in the list of commands (argbackq) was not advanced. This caused
the wrong command to be executed later if the outer word contained another
command substitution.
Example:
echo "${unsetvar#$(echo a)}$(echo b)"
wrote "a" but should write "b".

looked like it might handle reverse attributes, but it actually handles
conversion of attributes in the direction indicated by the new name.
Reverse attributes are just broken.
Rename scteken_attr() to scteken_te_to_sc_attr(). scteken_attr() looked
like it might give teken attributes, but it actually gives sc attributes.
Change scteken_te_to_sc_attr() to return int instead of unsigned int.
u_char would be enough, and it promotes to int, and syscons uses int
or u_short for its attributes everywhere else (u_short holds a shifted
form and it promotes to int too).
This change just does cleanups missed in r56043 17 years ago. The
default attributes were still stored in structs for the purpose of
changing them and passing around pointers to the defaults, but r56043
added another layer that made the defaults invariant and only used for
initialization and reset. Just use the defaults directly. This was
already done for the kernel defaults. The defaults for reverse
attributes aren't actually used, but are ignored in layers that no
longer support them.
- Not set BufferLength caused receive of empty ATIOs.
- CDB length guessing was broken at least for RC16.
- mpt_req_untimeout() was called with wrong req parameter.
- Sense data reporting was broken in several ways.
With this change my LSI7204EP-LC can pass at least basic tests as target.
The code is still far from perfect, but finally I found second hw/driver
after isp(4) that really can work in CAM target mode.

on sparc64 but still calls it. On other non-x86 arches, it should
compile but might not work.

When dlclose(3) unloads an object with filtees, it recursively calls
dlclose(3) on each filtee in free_needed_filtees(). Introduce
dlclose_locked() helper, called from free_needed_filtees() instead of
dlclose(), and pass the bind lockstate down to avoid recursing.

Add support for using mutexes during KDB and shutdown. This is also
required for doing mode-switching during panic for drm-next.
Add new mutex functions mutex_init_witness() and mutex_destroy()
allowing LinuxKPI mutexes to be tracked by witness.
Declare mutex_is_locked() and mutex_is_owned() like inline functions
to get cleaner warnings. These functions are used inside WARN_ON()
statements which might look a bit odd if these functions get fully
expanded.
Give mutexes better debug names through the mutex_name() macro when
WITNESS_ALL is defined. The mutex_name() macro can prefix parts of the
filename and line number before the mutex name.
