( and where appropriate the destruction) of the pcb mutex to the init/finit
functions of the pcb zones.
This allows locking of the pcb entries and race condition free comparison
of the generation count.
Rearrange locking a bit to avoid extra locking operation to update the generation
count in in_pcballoc(). (in_pcballoc now returns the pcb locked)
I am planning to convert pcb list handling from a type safe to a reference count
model soon. ( As this allows really freeing the PCBs)

important for embedded systems. This change was done in a ABI compatible
way. The pointer is still there, it just points to an empty string instead
of the description.

pmap_clear_ptes() is already convoluted. This will worsen with the
implementation of superpages. Eliminate it and add pmap_clear_write().

- Copy ethernet firmware down in small chunks so as to avoid bugs
in early versions of the bootstrap firmware.
- Attempt to "adopt" the running firmware if we cannot load a suitable
firmware image via firmware(9).
- Separate firmware validation into its own routine, and check the
major/minor driver/firmware ABI version.
instead of doing the first load with the BUS_DMA_NOWAIT flag. On 4.x with
PAE and > 4gb of RAM this proved disastrous if there weren't enough bounce
pages as amr_mapcmd() would return failure but the callback would later
fire once enough bounce pages were available and would then overwrite
another command's S/G list.

smb_co_init() to return with the lock held.

for OpenSSL to load engines run-time, e.g. for using the opensc
engine port.
The OpenSSL Configure script enables DSO support on FreeBSD by
default, we just don't use the Configure script during OpenSSL builds
in the base system.
This is committed to -CURRENT now (before OpenSSL 0.9.8b import), so
it can be tested at bit in -CURRENT before being MFC'ed to 6-STABLE.
