The algorithm used by nfscl_getopen() could have resulted in
multiple instances of the same lock_owner when a process both
inherited an open file descriptor plus opened the same file itself.
Since some NFSv4 servers cannot handle multiple instances of
the same lock_owner string, this patch changes the algorithm
used by nfscl_getopen() in the new NFSv4 client to keep that
from happening. The new algorithm is simpler, since there is
no longer any need to ascend the process's parentage tree because
all NFSv4 Closes for a file are done at VOP_INACTIVE()/VOP_RECLAIM(),
making the Opens indistinct w.r.t. use with Lock Ops.
This problem was discovered at the recent NFSv4 interoperability
Bakeathon.
Add an option to have a fail point term only execute when run by a
specified pid. This is helpful for automated testing involving a global
knob that would otherwise be executed by many other threads.

Modify the new NFSv4 client so that it appends a file handle

instances of the same lock_owner4 string, at least not in a
compatible way. This patch avoids having multiple instances,
except for one unusual case, which will be fixed by a future commit.

- The recent change to increase the zfsboot size to 64k made a few BIOSes
unhappy (probably they don't handle crossing the 64k boundary, etc.).
Fix this by changing zfsldr to use a loop reading from the disk one
sector at a time. To avoid trashing the saved copy of the MBR which is
used for disk I/O, read zfsboot2 at address 0x9000. This has the
advantage that BTX no longer needs to be relocated as it is read into
the correct location. However, the loop to relocate zfsboot2.bin can
now cross a 64k boundary, so change it to use relative segments instead.
(This will need further work if zfsboot2.bin ever exceeds 64k.)
While here, stop storing a relocated copy of zfsldr at 0x700. This was
only used by the xread hack which has recently been removed (and even
that use was dubious). Also, include the BIOS error code as hex when
reporting read errors to aid in debugging.
- Remove the fake BPB from zfsldr. zfsldr doesn't support booting from
floppies, so it will not be used as the start of an emulated floppy
image on a bootable CD which is what the fake BPB was used for.
- Only check that EDD packet mode is available once at the start of
zfsldr rather than for each disk sector now that we read data in one
sector at a time. As a result, collapse the remaining bits of read
up into nread and rename nread to read.
