comparing regular files. Add a SIGSEGV handler to make its
behavior less surprising when a read error occurs. The handler
does not attempt to distinguish errors from file truncation, but
anyone actively modifying a file while trying to compare it
shouldn't even expect something sane to happen.

changed since this code was written:
- The ng_ether_input_p hook only accepts two arguments now: the pointer
to the ether header structure is gone.
- It's no longer necessary to cons up a fake ether header before passing
incoming packets to BPF_MTAP().
ng_fec_input() has been modified to account for these two changes.
Running tcpdump on fec0 should work now.

- the mutex aac_io_lock protects the main codepaths which handle queues and
hardware registers. Only one acquire/release is done in the top-half and
the taskqueue. This mutex also applies to the userland command path and
CAM data path.
- Move the taskqueue to the new Giant-free version.
- Register the disk device with DISKFLAG_NOGIANT so the top-half processing
runs without Giant.
- Move the dynamic command allocator to the worker thread to avoid locking
issues with bus_dmamem_alloc().
This gives about 20% improvement in most of my benchmarks.
turns runs its tasks free of Giant too. It is intended that as drivers
become locked down, they will move out of the old, Giant-bound taskqueue
and into this new one. The old taskqueue has been renamed to
taskqueue_swi_giant, and the new one keeps the name taskqueue_swi.

from the filesystem size field to the filesystem maximum blocksize
field. The problem is that older versions of growfs updated only the
new size field and not the old size field. This resulted in the old
(smaller) size field being copied up to the new size field which
caused the filesystem to appear to fsck to be badly trashed.
This also adds a sanity check to ensure that the superblock is not
being updated when the filesystem is mounted read-only. Obviously
such an update should never happen.

post-deinstall script, the variable intended to hold the name of that
script would be used uninitialized. In some cases, fexists() would
succeed, causing pkg_delete to try to chmod +x it, then execute it,
resulting in bizarre error messages such as:
.//: Permission denied
This bug would normally only occur when multiple packages were
specified on the command line; otherwise post_script would be located
in a previously unused part of the stack, and implicitly (but quite
accidentally) initialized to all-zeros.
