uname/gname lookup cache from bsdtar)
* Format device number instead of size for device nodes
* Format date.
There's still a few improvements that I could copy from
bsdtar, especially the locale-aware safe_fprintf() code
and the locale-aware setup for day_first date formatting.
(And, of course, I need to think through a clean way to
push this stuff down into libarchive.)

This iterates over output strings using mbtowc() to identify

wide character is printable, the original bytes are passed
through. Otherwise, we expand characters into C-style
\-escape sequences.

Bring in updated jail support from bz_jail branch.
This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..
SCTP support was updated and supports IPv6 in jails as well.
Cpuset support permits jails to be bound to specific processor
sets after creation.
Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.
DDB 'show jails' command was added to aid debugging.
Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.
Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.
Bump __FreeBSD_version for the afore mentioned and in kernel changes.
Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their
help, ideas and review on cpuset and SCTP support.
- Robert Watson (rwatson) for lots and lots of help, discussions,
suggestions and review of most of the patch at various stages.
- John Baldwin (jhb) for his help.
- Simon L. Nielsen (simon) as early adopter testing changes

other channels.

This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system
creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache.
Huge performance improvements mostly for random read of mostly
static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up
operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored
on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.

- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one
can select from one of three failure modes:
- panic - panic on write error
- wait - wait for disk to reappear
- continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed
by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.

subtle why it comes out the way it does. Once you realize that it
depends on the archiving order, it's also important to realize that
filesystem differences aren't going to break this case. (Some of the
other tests have had to be extensively rewritten to make them
independent of the order in which a particular filesystem returns file
entries.)
(This commit also serves to note the PR number that I accidentally
omitted from the previous commit.)

good job writing this test; it exercises a lot of subtle cases. The
trickiest one is that a hardlink to something that didn't get
extracted should not itself be extracted. In some sense, this is not
the desired behavior (we'd rather restore the file), but it's the best
you can do in a single-pass restore of a tar archive.
The test here should be extended to exercise cpio and newc formats as
well, since their hardlink models are different, which will lead to
different handling of some of these edge cases.

This replaces the getopt()/getopt_long() wrapper, the old-style
argument rewriter and the associated configuration glue with a more
straightforward custom command parser. In particular, this ensures
that bsdtar will have consistent option parsing on every platform,
regardless of whether the platform supports getopt_long().

-A Display the apparent size instead of the disk usage. This can be
helpful when operating on compressed volumes or sparse files.
-B blocksize
Calculate block counts in blocksize byte blocks. This is differ-
ent from the -k, -m options or setting BLOCKSIZE and gives an
estimate of how much space the examined file hierachy would
require on a filesystem with the given blocksize. Unless in -A
mode, blocksize is rounded up to the next multiple of 512.
The former is similar to GNU's du(1) --apparent-size. The latter is
different from what GNU's du(1) -B does, which is equivalent to setting
BLOCKSIZE in our implementation and is rather pointless as it doesn't add
any real value (i.e. you can achieve the same with a simple awk-script).
No change in the normal output or processing.

Use ioctl() to get the window size in vmstat(8), and force a new
header to be prepended to the output every time the current window
size changes. Change the number of lines before each header to the
current lines of the terminal when the terminal is resized, so that
the full terminal length can be used for output lines.

script mode like the MRI(Microtec Research Inc.) "librarian" program.
Originally this option is provided by Binutils ar(1) to ease the
transition for developers who are used to writing "librarian" scripts.
We added this option to BSD ar(1) because:
1. Further improve the compatibility with Binutils ar(1).
2. There are still a few software using this -M option. (at least one
in our ports collection)

HAVE_STRUCT_STAT_ST_FLAGS, Linux support depends on the
existence of the appropriate ioctl() options. In particular,
this should fix some nagging compile errors on Linux platforms
that don't have e2fsprogs-devel installed.
In particular:
* tar -x -P follows symlinks to existing dirs, but not without -P
* symlinks to files are always replaced
* broken symlinks are always replaced
After the MPSAFE TTY import we support an additional rlimit, called
RLIMIT_NPTS. This limit allows you to cap the amount of pseudo-terminals
allocated by one user.
We forgot to add support for this limit to limits(1), which means it
crashed. Add the proper bits to make it work like it should.
Unfortunately not all shells actually implement the RLIMIT, so
unfortunately I suspect it to be broken with certain shells.
