with an extra space, it can be viewed as expected.

Apparently libgcc_s has always included libcompiler_rt's Makefile.inc
without first including bsd.compiler.mk, even though Makefile.inc used
COMPILER_TYPE already. It looks like we were just lucky that the
expression was not malformed.

This commit reverts 8db56defa7,
rolling back the vendor import of xz 5.6.0 and restoring the
package to version 5.4.5.
The revert was not directly due to the attack (CVE-2024-3094):
our import process have removed the test cases and build scripts
that would have enabled the attack. However, reverting would
help to reduce potential confusion and false positives from
security scanners that assess risk based solely on version
numbers.
Another commit will follow to restore binary compatibility with
the liblzma 5.6.0 library by making the previously private
symbol (lzma_mt_block_size) public.

Before a protocol specific control block started to embed inpcb in self

at it.
Retain kf_sock_inpcb field in the struct kinfo_file in <sys/user.h>. The
exp-run detected a minimal use of the field in ports:
* sysutils/lsof - patched upstream
* net-mgmt/netdata - patch accepted upstream
* emulators/qemu-user-static - upstream master branch seems not using
the field anymore
We can keep the field around for some time, but eventually it may be
reused for something else.

This adds support for two new diff algorithms, Myers diff and Patience
diff.
These algorithms perform a different form of search compared to the
classic Stone algorithm and support escapes when worst case scenarios
are encountered.
Add the -A flag to allow selection of the algorithm, but default to
using the new Myers diff implementation.
The libdiff implementation currently only supports a subset of input and
output options supported by diff. When these options are used, but the
algorithm is not selected, automatically fallback to the classic Stone
algorithm until support for these modes can be added.

TCP_USE_DDP is a kernel-only macro, so we must exclude it in
libsysdecode to avoid breaking the build.
Fixes: 3d0a736796 ("tcp: Add a new kernel-only TCP_USE_DDP [...]")
The (optional) third argument of fcntl is sometimes a pointer so change
the type to intptr_t. Update the libc-internal defintion (actually used
by libthr) to take a fixed intptr_t argument rather than pretending it's
a variadic function. (That worked because all supported architectures
pass variadic arguments as though the function was declared with those
types. In CheriBSD that changes because variadic arguments are passed
via a bounded array.)

Undo the 80-bit "stub" implementation of the 128-bit long double
tgammal(3) function. The latest (as of Feb 2024) version of the
src/contrib/arm-optimised-routines library includes a standalone,
full 128-bit replacement. This needs a small bit of wrapping to
fit it in, but is otherwise a drop-in replacement.
Testing this is hard, as most maths packages blow up as soon as
their 80-bit floating-point capability is exceeded. With 128-bit
tgammal(), this is easy to do, and this is the range that needs to
be checked the most carefully. Using my copy of Maple, I was able
to check that the output was within a few ULP of the correct answer,
right up to the point of 128-bit over- and underflow. Additionally,
the results are no worse, and indeed better than the 80-bit version.
Steve Kargl sent me his libm testing code, which I used to verify
that the excpetions for certain key values were correct. Tested in
this case were +-Inf, +-NaN, +-1 and +-0.
