Unconditionally freeing a page is not good, especially if it is the page
that was wired by the caller. The checks are picked up from
kern_sendfile.

Merge from UFS r231313:
This change first attempts the uiomove() to the newly allocated
(and dirty) buffer and only zeros it if the uiomove() fails. The
effect is to eliminate the gratuitous zeroing of the buffer in
the usual case where the uiomove() successfully fills it.

credentials to the kernel rpc. Modify the NFSv4 client to add
support for the gssname and allgssname mount options to use this
capability. Requires the gssd daemon to be running with the "-h" option.

- Fix sysctl wrapper for sysfs attributes to properly handle new string
values similar to sysctl_handle_string() (only copyin the user's
supplied length and nul-terminate the string).
- Don't check for a trailing newline when evaluating the desired operating
mode of a mlx4 device.

FastISel can only append to basic blocks.
Compute the insertion point from the end of the basic block instead of
skipping labels from the front.
This caused failures in landing pads when live-in copies where inserted
before instruction selection.
I missed this change in r252720; without it, certain compilation flags
can cause exception labels to not be generated, but still referenced,
leading to link errors.

As of 2013, DST starts at 02:00 on the Friday before the last

October 1, unless it occurs on the second day of the Jewish Rosh
Hashana holiday, in which case DST ends a day later (i.e. at 02:00
the first Monday after October 2). [Rosh Hashana holidays are
factored in until 2100.]
For now, sandboxing is done only if -n option was specified and neither -z nor
-V options were given. Because it is very common to run tcpdump(8) with the -n
option for speed, I decided to commit sandboxing now. To also support
sandboxing when -n option wasn't specified, we need Casper daemon and its
services that are not available in FreeBSD yet.
- Limit file descriptors of a file specified by -r option or files specified
via -V option to CAP_READ only.
- If neither -r nor -V options were specified, we operate on /dev/bpf.
Limit its descriptor to CAP_READ and CAP_IOCTL plus limit allowed ioctls to
BIOCGSTATS only.
- Limit file descriptor of a file specified by -w option to CAP_SEEK and
CAP_WRITE.
- If either -C or -G options were specified, we open directory containing
destination file and we limit directory descriptor to CAP_CREATE, CAP_FCNTL,
CAP_FTRUNCATE, CAP_LOOKUP, CAP_SEEK and CAP_WRITE. Newly opened/created
files are limited to CAP_SEEK and CAP_WRITE only.
- Enter capability mode if -n option was specified and neither -z nor -V
options were specified.
