fails, since no MMIO resource was allocated. If a10_intr_pic_attach()
fails after the MMIO resource has been allocated, release it before

Replace the unconditional fflush(stdout) in grep_printline and
procmatches with a periodic timer that flushes at most once every
100ms. This preserves interactive responsiveness (grep | tee,
grep | tail -f) while avoiding 1M+ write(2) syscalls when
processing large inputs.
The flush interval is tracked via clock_gettime(CLOCK_MONOTONIC)
and a static timespec. --line-buffered continues to flush
immediately via setlinebuf(3), as before.
Benchmark on 1M lines (37MB output to file):
unconditional fflush: 1.90s (sys 1.22s)
periodic 100ms timer: 0.49s (sys 0.007s)

Specifically, do not let vtryrecycle() to recycle a used vnode. It is
possible for a vnode to be vref-ed or vuse-ed lockless after it is held
by vhold_recycle_free(). Then, since vtryrecycle() does not recheck the
hold count, we might end up freeing vused vnode.
Since vget_finish() increments v_usecount after obtaining the vnode
lock, we would observe the hold reference anyway when the parallel
vget() is blocked waiting on the vnode lock.

[ToolChains][FreeBSD] Set default Linker to LLD for FreeBSD (#190596)
When the linker is specified as ld, toolchain applies special handling
by invoking (triple)-ld instead of resolving ld via standard PATH
lookup. This causes GNU ld installed via the system package manager to
take the precedence (since (triple)-ld appears earlier in the search
path), effectively overriding ld.lld.
As a result, we set the default Linker on FreeBSD to ld.lld to indicate
we want to use lld by default.

The extra search for an FEXEC fufh shall be removed, since readdir
is only supposed to be called on a directory opened with FREAD. The
sole exception is NFS, which will call VOP_READDIR with directories that
aren't open at all. fuse already has special code to handle that.
Also remove the fuse_filehandle_get_dir() function, since it's not
used anywhere else.

However, loopback routes may already be added by the kernel.
Therefore, re-adding them triggers an `EEXIST` error on every boot.

When interface was connected to a link partner with a cable
type limitting maximum supported speed, e.g. SFP+ cable
in 25G port, driver incorrectly saved a supported speed
as the user configured speed. This prevented interface
from using all supported speeds after switching cable to SFP28.
Link was established at 10G as supported by previously used
SFP+ cable. Don't set user requested speed unless actually
configured by an user, to allow automatic selection of highest
available speed. Only when user sets custom config
using advertise_speed sysctl save it and try
to apply after cable is changed.
Also don't save initial supported speeds if FW supports
reporting default PHY config.

When we snl_init_writer() we allocate memory in the struct snl_state in the struct pfctl_handle.
This memory was never released again, leading to a memory leak. We still
had a reference to the memory and would release it on pfctl_close()
(so valgrind did not detect it as a leak), but long-lived users (e.g.
bsnmpd) would eventually run out of memory.
Explicitly reset the snl_state when we're done to prevent this.

Given the fact that we no longer build the fips provider and the fips
provider build process (including sources) is very prescribed to
specific build steps and source versions, there's no reason why we need
