In the search for contiguous pages, as each page segment is examined,
check to see if the free list set for the next page segment differs
from the set for the current segment, and avoid a pointless search if
they do not differ.

The limit may later be updated by the "set limit" directive in pf.conf.
UMA does not permit a limit to be set on a zone after any items have
been allocated from a zone.
Other UMA zones used by pf do not appear to be susceptible to this
problem: they either set a limit at zone creation time or never set one
at all.

In order to clean up the layout of the manual page, let's keep
parameters in the end of the DESCRIPTION section. This patch does not
change any content, it's meant to only move the content around before

If the pfctl_add_eth_rule() ioctl fails return the errno, not the error
returned by ioctl(). That will give us slightly more insight into what
went wrong, because ioctl() would always return -1.

In vmbus_pcib_prepopulate_bars(), after writing all 1's to the
avialable device bars, those without being configured by device driver
are also set to its initialized values. However, this could cause
weird problem which results to device failure. The issue has been
reported to happen on LSI 9211-8i HBA card for DDA access on Hyper-V.
Writing back the orignal BAR values seem to work around this problem.

fstyp looks for a 0x55 0xAA signature at offset 510, but this is not
required by specifications and is not proivded by the Raspberry Pi Nano
bootloader.
We should really remove the signature check and implement a more
comprehensive BPB validation instead, but it will require more
investigation and testing. For now just add a special case for the
Raspberry Pi Nano bootloader, to avoid introducing regressions or new
false positives.

32-bit architectures other than i386 have 64-bit time_t which results
in a struct timespec with 12 bytes for tv_sec and tv_nsec, and 4 bytes
of padding. Zero the padding holes in struct stat32 and struct
freebsd11_stat32.
i386 has 32-bit time_t; struct timespec is 8 bytes and has no padding.
Found by inspection, prompted by a report by Reno Robert of Trend Micro
Zero Day Initiative. The originally reported issue (ZDI-CAN-14538) is
already fixed in all supported FreeBSD versions (it was addressed
incidentally as part of the 64-bit inode project).

- There is no need to mention in the synopsis that -f can be a list of
comma-separated type:format pairs. Let's keep it simple instead.
- Mention that -f can be supplied multiple times.

As documented, the -C flag can only be used on its own. Any other
