Correct an assertion in the code to traverse the list of locks to find an
earlier acquired lock with the same witness as the lock currently being
acquired. If we had released several earlier acquired locks after
acquiring enough locks to require another lock_list_entry bucket in the
lock list, then subsequent lock_list_entry buckets could contain only one
lock instance in which case i would be zero.

ia64 ABI breaker:
Don't force 16-byte alignment at run-time. Do it at compile-time.
This saves us the pointer fiddling by the setjmp functions and
reduces complexity. While here, increase the jmp_buf by 16 bytes
to an even 512 bytes. Coincidentally, due to the way alignment
was handled prior to this change, the jmp_buf has not changed in
size, but only in how the space is used. Prior to this change
the 16 bytes were reserved for enforcing alignment; now they are
reserved by us for future extensions.
Therefore, this ABI breaker is relatively save: the failure is
always an alignment trap.

Given that we have 3 places to document UUID related information,
namely uuidgen(1), uuidgen(2) and uuid(3), the following division
has been choosen:
uuidgen(1) A description of the command line utility,

uuidgen(2) A mostly technical description of UUIDs.
uuid(3) A description of the functions and other
programmer oriented UUID information.
According to the division: add more technical contents.

Write the boot block to the first 16 sectors of all partitions, instead of
always to the first 16 sectors of the disk. The firmware reads the boot
code from a partition, defaulting to 'a' if none is specified, which only
corresponds to the first 16 sectors of the disk if 'a' is first. Solaris
often makes the swap partition first, instead of the root partition, and
users expect to be able to do the same with freebsd as well. This also
allows one to temporarily boot from another partition if the boot block
on the root partition gets scrambled somehow.

General cleanup:
o Remove all code guarded by !defined(__ia64__). This file is
specifically written for ia64,
o Handle the case when read_block() or write_block() fails. We
don't want sysinstall(8) to signal a thumbs-up on error,
o Set the starting (cyl,hd,sect) triple to 0xFFFFFF when either
bios_hd or bios_sect is zero or the LBA us not representable
with the triple. In that case automaticly initialize the
ending triple with 0xFFFFFF as well,
o Reindent Write_Int32() as it was different than the rest of
the file,
o Remove some unused variables that appeared to be used but
were effectively useless.
o Plug a memory leak: The second timne we read the MBR, we write
out a modified block, but didn't free the memory after writing.
o Replace d1->sector_size with 512 when we read/write the MBR.
We ignore the sector size in cases we shouldn't but adhered to
it in cases it would be wrong if the sector_size wasn't 512.
This file should eventually be rewritten to write out a GPT. For
now, a MBR will do...

Change the device path representation in libofw to use the full firmware
