nfscl: Disable use of callbacks for NFSv4.0
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 client. This is the same behavior as
occurred when the nfscbd(8) daemon was not running.
This change allowed a function called nfscl_getmyip()
to be removed from the kernel, which is nice since
maintaining this function was bothersome, due to its
use of routing, etc.

ufs: support unmapped bufs for indirect blocks in bmap
Use unmapped bufs for indirect block buffers in bmap, and use sf_bufs
for transient mapping them when we need to read the specific pointer.
[kib note: I changed the original patch to use sf_buf instead of
explicit DMAP utilization, making the change MI].

ptrace: clear TDP_USERWR after transparent attach only on attach
The flag indicates that the modifying ptrace op was issued, and clearing
it after transparent attach is needed to not leak the flag to later
operations, since it is cleared on the syscall enter.
But clearing it there unconditionally is too strong. The clearing
should be only done for attach situation.

bsdinstall: do pkgbase installations with the "script" command
"bsdinstall script" will now do a pkgbase installation by default. The
system components to install can be specified in the COMPONENTS
variable, and have the same names as those used in the interactive
installer. bsdinstall will still do a legacy distset installation if
DISTRIBUTIONS is defined in the installerconfig file.

bq_insert: delay the BUF_UNLOCK if not bd_flush()ing
Reduce bufqueue lock contention by delaying the BUF_UNLOCK to after
dropping the bufqueue lock. Still do the early BUF_UNLOCK if we
actually have to bd_flush.

Make "make update-packages" idempotent
If the user runs "make update-packages" without bumping BRANCH, then it
isn't possible to copy packages from the old location to the new one
(because the two locations are the same). So just skip that step.

Fix LOCAL_PEERCRED in 32-bit compat mode
Previously the cr_pid field would be incorrectly copied to userland, due
to a size mismatch between the structure as defined in 32-bit vs 64-bit
builds. Fix it by converting the structure before copying it to
userland.
