Unify all the wifi *_ioctl routines

- Move ieee80211_start_all() to SIOCSIFFLAGS.

- Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no
affect as there is no input/output path in the vap parent. The vap code
will handle the reinit of the mac address changes.

Rework how kgdb manages kernel and vmcore files to be a bit more gdb-ish
so that kgdb can be used more like a normal gdb:
- Load the kernel via the standard 'exec' target and allow it to be changed
via the 'file' command.
- Instead of explicitly loading the kernel file as the mail symbol file
during startup, just pass it to gdb_main() as the executable file.
- Change the kld support (via shared libraries) to cache the address of
the linker_files and linker_kernel_file variables in addition to the
offsets of various members in 'struct linker_file'.
- When a new symbol file is loaded, recompute the addresses and offsets
used by the kld support code.
- When a new symbol file is loaded, recalculate the ofs_fix variable to
account for the different ways a trapframe can be passed to trap
frame handlers in i386. This is done by adding a MD
kgdb_trgt_new_objfile() hook that is empty on all but i386.
- Don't use the directory name of the kernel specified on the command
line to find kernel modules in the kld support code. Instead,
extract the filename of the current executable via exec_bfd. Now
the 'kernel' variable is private to main.c again.
- Make the 'add-kld' command explicitly fail if no executable is loaded.
- Make the support for vmcores a real core-dump target that opens the
kernel and vmcore on open and closes the kvm connection when closed, etc.
- The 'core' command can now be used to select a vmcore to use, either
a crash dump file or /dev/mem for live debugging.
- The 'detach' command can be used to detach from a vmcore w/o attaching
to a new one.
- kgdb no longer explicitly opens a core dump during startup and no longer
has to use an atexit() hook to close the kvm connection on shutdown.
- Symbols for kld's are automatically loaded anytime a core is opened.
Also, the unread portion of dmesg is dumped just as it was done on kgdb
startup previously.
- Don't require either a remote target or core dump if a kernel is specified.
You can now just run 'kgdb kernel' similar to running gdb on an executable
and later connect to a remote target or core dump.
- Use a more relaxed way to verify remote targets specified via -r.
Instead of explicitly allowing a few non-file target specifications,
just assume that if stat() on the arg and on "/dev/" + arg both fail
that is some non-file target and pass it to gdb.
- Don't use a custom interpreter. The existing kgdb_init() hook and the
target_new_objfile() hook give us sufficient hooks during startup to
setup kgdb-specific behavior now.
- Always add the 'proc', 'tid', and 'add-kld' commands on startup and not
just if we have a core dump. Currently the 'proc' and 'tid' commands do
not work for remote targets (I will fix at least 'tid' in the next round
of changes though). However, the 'add-kld' command works fine for
loading symbols for a kernel module on a remote target.
- Always setup the 'kld' shared library target operations instead of just
if we have a core dump. Although symbols for kernel modules are not
automatically loaded when connecting to a remote target, you can do
'info sharedlibrary' after connecting to the remote target and kgdb will
find all the modules. You can then use the 'sharedlibrary' command to
load symbols from the module files.
- Change kthr_init() to free the existing list of kthr objects before
generating a new one. This allows it to be invoked multiple times
w/o leaking memory.
Add support for the BCM5906[M] adapters. These adapters only support
10/100 operation and place the mailbox registers at a different offset.
They also do not have an EEPROM, so the MAC address must be read from
NVRAM instead.

- Add a global variable 'fbsdcoreops_suppress_target' that can be set to
force the FreeBSD multithreaded core target to not register any target
for handling core dumps. This is analogous to the
'coreops_suppress_target' variable that GDB provides for suppressing the
default core dump target. KGDB will use this new variable so it can
provide its own core dump target that uses libkvm to work with vmcore
files.
- Adjust the long name and documentation of the FreeBSD multithreaded core
dump target so it better matches what GDB's core dump target uses.

Use kgdb_parse() instead of libkvm(3) to read the first instruction from

When writing trailers in sendfile(2), don't call kern_writev()
while holding the socket buffer lock. These leads to an
immediate panic due to recursing the socket buffer lock. This
bug was introduced in uipc_syscalls.c:1.240, but masked by
another bug until that was fixed in uipc_syscalls.c:1.269.
Note that the current fix isn't perfect, but better than
panicking: normally we guarantee that simultaneous invocations
of a system call to write on a stream socket won't be
interlaced, which is ensured by use of the socket buffer sleep
lock. This is guaranteed for the sendfile headers, but not
trailers. In practice, this is likely not a problem, but
should be fixed.

With rev 1.24 of sys/powerpc/powermac/macio.c, we now get a
total of 6 interrupt resources for scc(4) on macio(4). This
is 3 per channel, of which the 1st of each channel is the
interrupt associated with the SCC. The other 2 are for DMA
operation.
Change scc_bfe_attach() to accept an argument that's the
number of interrupts per channel (ipc) and change each bus
front-end (bfe) to pass that argument through a wrapper
for the device_attach method.
For now, we only allocate the 1st interrupt of each channel
to perserve behaviour.
Take into account the size of the interrupt cell. It's determined
by the parent for interrupt resources. This corrects parsing of
the interrupts property.
With parsing of the property fixed, add all interrupts to the
resource list. Bump the max. number of interrupts from 5 to 6
as scc(4) attached to macio(4) has 6 interrupts (3 per channel).
