libgomp: Update to version 4.3.5.
bring initial BSD support from upstream.
This was not meant to be MFC'd at first but the original OMP support
for FreeBSD was in very poor shape. The effect of this change should
be minimal as all ports are already using the version of libgomp that
comes with the gcc ports. The local libgomp is planned to be disabled
for platforms that are not using older gcc by default so this version
of libgomp will not be shipped in tier-1 platform releases.

Add a hint that "device ctl" kind of depends on "device iscsi".
It actually doesn't - "device ctl" automatically pulls in ICL, which
would normally be a part of iscsi.ko. However, doing it that way makes
iscsi.ko unloadable, and building ctl.ko without iscsi.ko (using
MODULES_OVERRIDE) results in ctl.ko that is unloadable, due to missing
symbols that would be resolved to iscsi.ko. And since the symbols
are named "icl_whatever", it's not obvious that it's iscsi.ko that's
required.

MAXBSIZE defines both the largest UFS block size and the
largest size for a buffer in the buffer cache. This patch
defines a new constant MAXBCACHEBUF, which is the largest
size for a buffer in the buffer cache. Having a separate
constant allows MAXBCACHEBUF to be set larger than MAXBSIZE
on a per-architecture basis, so that NFS can do larger read/writes
for these architectures. It modifies sys/param.h so that BKVASIZE
can also be set on a per-architecture basis.
A couple of cases where NFS used MAXBSIZE instead of NFS_MAXBSIZE
is fixed as well.

MFC r282482: cp: Remove fts sorting.
In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.
The sorting reorders multiple arguments passed to cp, which may be
undesirable.
Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().
NetBSD removed the sorting in 2009.
On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).

pbufs is a limited resource, and their allocator is not SMP-scalable.

allocate bio just here. If buffer needs kernel mapping, then pbuf is
still allocated, but used only as a source of KVA and storage for a list
