Very old versions of gcc defined _BIG_ENDIAN and _LITTLE_ENDIAN. So to
work around that, we undefined them here. However, that causes problems
for programs that do:

result of weirdly nested includes in the ports world that are hard to
unwind, drop this workaround to help more ports build out of the box.
If there's still an issue here (and my testing hasn't shown it), we'll
fix the issue in a brand-new way once I have a reproducer.

Modify tcp_connect() and tcp6_connect() to perform the check again, this

This obsolete system call is not supported by glibc. In ancient libc

FreeBSD-9 had introduced support for the full set of Unicode
characters to the parsing and processing of keymap character tables.
This support has been extended to cover the table for accented
characters that are reached via dead key combinations in FreeBSD-13.2.
New ioctls have been introduced to support both the pre-Unicode and
the Unicode formats and keyboard drivers have been extended to support
those ioctls.
This commit makes the ABI compatibility functions in the kernel
optional and dependent on COMPAT_FREEBSD13 in -CURRENT.
The kbdcontrol command in -CURRENT and 13-STABLE (before 13.2) has
been made ABI compatible with old kernels to allow a new world to be
run on an old kernel (that does not have full Unicode support for
keymaps).
This commit is not to merged back to 12-STABLE or 13-STABLE. It is
part of review D38465, which has been split into 3 separate commits
due to different MFC and life-time requirements of either commit.

The definition of pre-Unicode keymap ioctls will be made optional and
dependent on COMPAT_FREEBSD13 in a follow-up commit to 14-CURRENT.
While we generally provide ABI compatibility for older binaries on
a new kernel, but not functionally extended userland programs on an
old kernel, it has been specifically requested to preserve ABI
compatibility for the kbdcontrol program for both these cases.
Passing the kernel configuration option COMPAT_FREEBSD13 to the build
of kbdcontrol will make ioctls visible to the build that are normally
hidden, but required to implement compatibility with kernels that only
support 8 bit characters in dead key maps.
This commit is not to be merged to any previous FreeBSD version and
it shall be reverted as soon as this type of ABI compatibility is no
longer deemed necessary (probably before 14-STABLE is branched).
This commit is a part of review D38465 and split off to allow it to be
reverted using the commit ID.
Support for the full range of Unicode character codes has been added
to the main keymap back in 2009, with compatibility shims added in
2011 (to support an older kbdcontrol command on a new kernel during
an upgrade from FreeBSD-8 to FreeBSD-9).
Unicode support for accented characters that are reached via dead key
combinations has been added just recently, again with compatibility
shims to allow all combinations of old/new kernel and old/new
kbdcontrol command to load and display the keymaps including the dead
key table. (But full Unicode in the dead key table requires both a new
kernel and kbdcontrol command.)
This commit makes the compatibility shims depend on the respective
compatibility ioctls (OGIO_KEYMAP, OPIO_KEYMAP, OGIO_DEADKEYMAP, and
OPIO_DEADKEYMAP) being defined in sys/kbio.h. This is true for all of
them in 13-STABLE, none in 12-STABLE (as of now), and will become
optional due to a follow-up commit to sys/kbio.h in -CURRENT.
This commit is the only part of review D38465 that should be merged
back to 12-STABLE and 13-STABLE.

Suppose that the cluster size is larger than page size. If the buffer
at the old EOF (before extending) was partial and dirty, it cannot be
automatically neither written out nor validated by the buffer cache,
since extending buffer adds invalid pages at the end.
Correct the buffer state by calling vfs_bio_clrbuf() on it, to mark
newly added and zeroed pages as valid.
Note that UFS is immune to the problem because ffs_truncate() always
allocate the block and buffer for the last byte of the file.
