r353150 added mnt_rootvnode and this seems to have broken NFS mounts when the
VFS_STATFS() called just after VFS_MOUNT() returns an error.
Then the code calls VFS_UNMOUNT(), which calls vflush(), which returns EBUSY.
Then the thread get stuck sleeping on "mntref" in vfs_mount_destroy().
This patch fixes this problem.

Otherwise nothing synchronizes with a concurrent conversion of the
socket to a listening socket.
Only the PF_LOCAL protocols implement pru_sense, and it is safe to hold
the socket lock there, so do so for now.

In a single-threaded program pthread_getspecific() always returns NULL,

Previously they included sys/dev/cx/machdep.h, but the cx driver was
retired in r359178. These drivers haven't had real development for
a decade or more so there's no real benefit in sharing this file; just
copy it to the ce and cp subdirs.
The devices supported by these drivers are obsolete ISA cards, and the
sync serial protocols they supported are essentially obsolete too.

We recently switched to including a blank line between ObsoleteFiles.inc
entries. I missed this when adding GCC 4.2.1 (because the change was
prepared months ago in a WIP tree); add a space for GCC 4.2.1 now, as
well as for the other entry after the switch.
There is no reason for diep to ever be NULL, since in that case we would
simply be leaking memory.

We support 10.3 as the minimum version to install from, which was
released in the mid-2010s. There's a lot of ancient ObsoleteFiles.inc
history that serves no purpose today; start by removing entries from
1999 and earlier.
Previously objcopy (elfcopy) --add-sections inserted new sections before
.shstrtab, but omitted them if there was no .shstrtab.
Now, after processing existing sections add new sections if they were
not yet added.

pci_iov_if.h was added to pci.h, but none of the kms-drm branches have
that. Rather than play whack a mole with the branches, move its inclusion to
linux_pci.c which is the only part of the code that needs it now.
Longer term, other solutions will be needed, but this gives us time to get those
deployed on all the supported versions.

This reduces the lines bouncing around between the driver rx ithread and

The inpcb needs to be locked when we update output packet options.
Otherwise it is possible for the IPV6_2292PKTOPTIONS handler to free
packet option structures while another thread is reading or updating
them.
Note that the option handler is still kind of broken. For instance it
frees all options before performing privilege checks for individual
options. However, this can be fixed separately.

Since we do build libsa with zlib, we can use zlib version instead.
