With --ignore-file-name-case we need to compare files regardless of
case. We need to propigate both names down to diffit so we can look up
the correct file when the names differ based on case, otherwise we try
to look up the file using the case from the a tree which might not be
discoverable if its case is different in the b tree.

UEFI provides a protocol for accessing randomness. This is a good way
to gather early entropy, especially when there's no driver for the RNG
on the platform (as is the case on the Marvell Armada8k (MACCHIATObin)
for now).
If the entropy_efi_seed option is enabled in loader.conf (default: YES)
obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a
"module" of name "efi_rng_seed" and type "boot_entropy_platform"; if
present, ingest it into the kernel RNG.

elfdump -E on an empty file would complain "Invalid argument" because
it tried to mmap zero bytes. With the -E flag, elfdump should
simply exit non-zero. For tiny files, the code would reference off
the end of the mapped region.
Ensure the file is large enough to contain an ELF header before mapping it.

Create a dedicated free state, in case the taskqueue worker is still pending,
to avoid re-activation of a freed send tag.

Use the send tag refcounting mechanism to refcount the RX- and TX- TLS
send tags. Then it is no longer needed to wait for refcounts to reach
zero when destroying RX- and TX- TLS send tags as a result of pending
data or WQE commands.
This also ensures that when TX-TLS and rate limiting is used at the same
time, the underlying SQ is not prematurely destroyed.

This contain mmap_read_lock, mmap_read_unlock and mmap_write_lock_killable
which are abstraction around down_read, up_read and down_write_killable.
Note that in Linux 5.8 mmap_sem was renamed to mmap_lock.
We might want to do the same at some point but some drivers still uses
the old mmap locking API.

Deleting hack.c cause the kernel to always be out of date:
$ make kernel
make: /usr/src/sys/amd64/compile/GENERIC/.depend.hack.pico, 1:
ignoring stale .depend for hack.c
:> hack.c
cc -shared -O2 -pipe ... -nostdlib hack.c -o hack.pico

cc -c -O2 -pipe ... -std=iso9899:1999 -Werror vers.c

Keeping hack.c in the compile directory causes no harm,
so there's no reason to delete it.
Also rename the file to "force-dyamic-hack.c" so it is
clear what the hack is aboug.

We disabled hw_scan for drivers not advertising SINGLE_SCAN_ON_ALL_BANDS.
Do not depend on this hw flag to set IEEE80211_FEXT_SCAN_OFFLOAD for
net80211 as otherwise scanning will never work.
Long-term we probably want to re-think how we do/integrate hw_scan
better in net80211.

There is a problem with some drivers, such as rtw88, asking for more
headroom than we currently can handle throughout the stack (we have
other legacy wireless driver in the tree with similar problems).
This may trigger an assertion in the TCP syncache where we are checking
for a reply to fit in MHLEN.
While for the moment we still copy data from mbufs to skbs,
we can simply disable the extra headroom request in ic_headroom and
deal with it ourselves (which we already did anyway).
Leave a link to the thread on freebsd-transport detailing more of the
problem so we can find it again and solve it here or there.

udp_set_kernel_tunneling() rejects new callbacks if one is already set.
Allow callbacks to be cleared. The use case for this is OpenVPN DCO,
where the socket is opened by userspace and then adopted by the kernel
to run the tunnel. If the DCO interface is removed but userspace does
not close the socket (something the kernel cannot prevent) the installed
callbacks could be called with an invalidated context.
Allow new functions to be set, but only if they're NULL (i.e. allow the
callback functions to be cleared).
