In particular, do not assume that vn_start_write() returns the same mp
as it was passed in, or never returns error.
Also be more accurate to return NULL vp and mp when error occured, to
catch wrong control flow easier.
Stop checking for NULL mp before calling vn_finished_write(), NULL mp
is handled transparently by the function.

Commit 774a36851e fixed the NFS server so that it could handle
ERELOOKUP returns from VOP calls by redoing the operation/RPC.
However, for NFSv4.0, redoing an Open would increment
the open_owner's seqid multiple times, breaking the protocol.
This patch sets a new flag called ND_ERELOOKUP on the RPC when
a redo is in progress. Then the code that increments the seqid
avoids the seqid increment/check when the flag is set, since
it indicates this has already been done for the Open.
r367672 modified UFS such that certain VOPs, such as
VOP_CREATE() will intermittently return ERELOOKUP.
When this happens, the entire system call, or NFS
operation in the case of the NFS server, must be redone.
This patch adds that support to the NFS server by rolling
back the state of the NFS request arguments and NFS
reply arguments mbuf lists to the condition they were
in before the operation and then redoing the operation.

scrmap is only used in the one compilation unit in all cases, make it static
rather than extern'ing it. There's little benefit, but it's easy to do.
It's unclear how this hasn't failed many builds before now, since it should
have cropped up sometime around deeper hierarchies getting a default WARNS.

[PowerPC] Do not emit HW loop when TLS var accessed in PHI of loop
exit
If any PHI nodes in loop exit blocks have incoming values from the
loop that are accesses of TLS variables with local dynamic or general
dynamic TLS model, the address will be computed inside the loop.
Since this includes a call to __tls_get_addr, this will in turn cause
the CTR loops verifier to complain. Disable CTR loops in such cases.

Previously having ficl/liblua in LIB32LIST with their respective option
turned OFF would be relatively harmless, as we wouldn't act on it unless we
were building the non-32 variant. As of ac5f382a9d, however, these are
now used for dependencies in some cases and must reflect what's actually
going to be built.
The change to kern_jail_set that was supposed to "also properly clean
up when attachment fails" didn't fix a memory leak but actually caused
a double free. Back that part out, and leave the part that manages
allprison_lock state.
Support for fractional seconds has become much more widespread since
this text was originally written.

Exiting processes that have been removed from allproc but are still
executing are not yet marked PRS_ZOMBIE, so they were not listed (for
example, if a thread panics during exit1()). To detect these
processes, clear p_list.le_prev to NULL explicitly after removing a
process from the allproc list and check for this sentinel rather than
PRS_ZOMBIE when walking the pidhash.
While here, simplify the pidhash walk to use a single outer loop.
