bhyve/virtio-scsi: Don't invoke iov_to_buf() in an assert() expression
If anyone would build bhyve with -DNDEBUG, any code in the expression
in assert() won't be executed. Instead put the return value in a
temporary variable to assert that it has the expected value.

lockf: Avoid spinning when operating on an fd
When operating on a file descriptor, acquire_lock() would ignore the
flags argument and always operate in non-blocking mode, resulting in
unnecessary busy-looping.

tail(1): Fix -r (reverse) to work on pseudo filesystems
Pseudo filesystems (e.g., procfs) advertise a zero file size.
Fix reverse() to handle such a case similarly as forward() so
that '-r' works on pseudo filesystems.

nfs_clsubs.c: Fix ncl_getcookie() when "pos" is negative
In ncl_getcookie(), a very large value for "off" for
a directory can result in "pos" being set to a bogus
value (including a negative one), due to truncation.
When "pos" is negative, is can skip past the
while (pos >= NFSNUMCOOKIES) loop and return a
bogus pointer instead of NULL.
This patch changes the type to u_int and also adds
a sanity check for a very large "off" to ensure that
a NULL pointer is returned for this case.
This bug has been in the code for decades and I am
not aware of any report of it causing a problem for
users.

devmatch: read linker.hints from all module paths
Previously, devmatch would stop at the first linker.hints file
found in kern.module_path. This meant modules installed in
/boot/modules/ were invisible to devmatch if /boot/kernel/
contained a linker.hints file (which it always does).
Merge hints from all directories in kern.module_path.
This allows third-party or out-of-tree kernel modules in
/boot/modules/ to be auto-loaded by devmatch just like
built-in modules.

man: Kill off MANSUBDIRs
Three architecture dependent manuals are installed to MANSUBDIRs,
creating at least two empty manual page directories on everyone's
boxxen. Move those manuals to their canonical area, enhancing clarity,
grepability, removing useless inodes, and increasing consistency with
the rest of the architecture dependent manuals which are unconditionally
installed, and noted at the top of the rendered manual.
