kern: replace several EBADF with EINVAL
EBADF semantic is that the passed fd is invalid, not that it is of wrong
type. Using EBADF in these places in kern_event.c and sys_procdesc.c
give bad examples to copy from.
Note that places in kern_event.c that checks KQ_CLOSING and return EBADF
are kept, since KQ_CLOSING is the transient state before the fd is
finally closed and become eligible for EBADF.

[net80211] Quieten the logging from ieee80211_vht_get_vhtflags()
The commit in Fixes: introduced logging the output bits from
ieee80211_vht_get_vhtflags(). This ends up causing quite a lot
of logging when net80211 is doing things like processing
received beacons.
So just remove the logging; if it's needed again then a developer
can add it back to that location, or just use dtrace to capture
the return value.

share/mk: Fix a heuristic in bsd.cpu.mk
When cross-building from MacOS we have MACHINE=arm64 MACHINE_ARCH=arm,
so bsd.cpu.mk infers that sizeof(long) == 4, but of course it isn't.
This breaks the bootstrap build of openssl, which tests
MACHINE_ABI:Mlong64 to decide whether to build ecp_nistp224.c. It
doesn't, and crypto/openssl/freebsd/include/openssl/configuration.h
undefines OPENSSL_NO_EC_NISTP_64_GCC_128, so we end up with a link
error.

nfsd: Fix the NFSv4 Readdir operation for an empty ZFS dir
Commit 9a3edc8 modified the behaviour of ZFS's
VOP_READDIR() such that it will reply EINVAL for
an offset past EOF on the directory.
This exposed a latent bug in the NFSv4 Readdir
code, which would attempt a Readdir with an
offset beyond EOF for a directory that consists
of only "." and "..". This happened because NFSv4
does not reply "." or ".." to the client and, after
skipping over them, attempted another VOP_READDIR().
This patch fixes the problem by checking the eofflag
for the case where all entries have been skipped over.

stand: Remove Spleen 32x64 fonts from INDEX
The Spleen 32x64 fonts cause some systems such as the AMD Framework 16
to boot extremely slowly. Adding screen.font="16x32" to
/boot/loader.conf is a partial workaround, but text displayed before the
boot menu still takes ~30 seconds to render on that laptop. With this
change, the same text renders immediately.
By leaving the font files in place but removing them from the INDEX,
users who want to use them can still load them manually. Once pending
work is committed to allow normal booting with these fonts, they can be
added back to the INDEX.

dem_kfree() is called from all over the place and should actually
