Upstream fixes for issues found with afl (Issue #417).
- Fix length checking.
Check both the captured length and the on-the-wire length (the latter
*should* be greater than or equal to the former, but that's not
guaranteed).
Add some additional length checks, so neither caplen nor length
underflow.
If we stop dissecting because the packet is too short, return 1, not 0,
as we've "dissected" what we can; 0 means "this is LLC+SNAP with an OUI
of 0 and an unknown Ethertype".

- Clean up length checks.
Check only the amount of length that matters at any given point; yes,
this means we do multiple checks, but so it goes.
We don't need to check for LLC+SNAP - llc_print() does that for us. We
do, however, need to check to make sure we can safely skip the Fore
header.

Strip is often used to modify existing files, rather than creating new
files. If the existing file has hard links or is a symbolic link, act as
if editing the file in place and preserve the links.

contrib/amd/hlfsd/homedir.c:497:8: error: address of array 'buf' will
always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
if (!buf || buf[0] == '\0')
~^~~
In the affected function, 'buf' is declared as an array of char, so it
can never be null. Remove the unecessary check.

Merge some cherry-picked fixes originating in OpenBSD
Check whether the version field is available before looking at it.
While we're at it, use ND_TCHECK(), rather than a hand-rolled check, to
check whether we have the full fixed-length portion of the IPv4 header.
commit c67afe913011138a2504ec4d3d423b48e73b12f3
Do more length checking. From OpenBSD.

Allows Clang to use LLVM's fixes-x18 option
This patch allows clang to have llvm reserve the x18
platform register on AArch64. FreeBSD will use this in the kernel for
per-cpu data but has no need to reserve this register in userland so
will need this flag to reserve it.
This uses llvm r226664 to allow this register to be reserved.
Patch by Andrew Turner.

AArch64: add backend option to reserve x18 (platform register)
AAPCS64 says that it's up to the platform to specify whether x18 is
reserved, and a first step on that way is to add a flag controlling
it.
