MFV r248590,248594:
Update libarchive to 3.1.2

Some of new features:
- support for lrzip and grzip compression
- support for writing tar v7 format
- b64encode and uuencode filters
- support for __MACOSX directory in Zip archives
- support for lzop compresion (external utility)

Update libarchive to 3.0.4

Update libarchive to 3.0.3

Some of new features:
- New readers: RAR, LHA/LZH, CAB reader, 7-Zip
- New writers: ISO9660, XAR
- Improvements to many formats, especially including ISO9660 and Zip
- Stackable write filters to write, e.g., tar.gz.uu in a single pass
- Exploit seekable input; new "seekable" Zip reader can exploit the Zip
Central Directory when it's available; the old "streamable" Zip reader
is still fully supported for cases where seeking is not possible.

FreeBSD is now using bsdtar 2.8.3.

Fixed dependencies (make checkdpadd).

Merge a bunch of refactoring from Joerg Sonnenberger to
isolate common code used by tar and cpio (and useful to other
libarchive clients). The functions here are prefixed with
"lafe" (libarchive front-end) to indicate their use.

Refactor the siginfo/sigusr1 handling. The read/write reporting
is sufficiently different that it was simpler to just put separate
reporting functions into read.c and write.c rather than try to have
a single all-purpose reporting function.
Switch to a custom function for converting int64_t to a string; in
the portable version, this saves a lot of configuration headaches
trying to decipher the platform printf().

Reformat the Makefile slightly.

Diff reduction compared to portable bsdtar 2.8: Move the
program name into a global, which eliminates an extra
argument from a lot of places.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Make sure to use up-to-date libarchive header files from source tree when
compiling tar and not the ones from /usr/include/.

Make -lcrypto usage dependent on whether or not we're building with OpenSSL.

Merge remaining changes from libarchive.googlecode.com:
* Add xz and lzma compression options
* Rename --format-options to simply --options
* Add --same-owner for GNU tar compat
* Add -lmd and -lcrypto to fix link
* Documentation

Update version to 2.6.901a to indicate this is synced up with r745 of
libarchive.googlecode.com (except for the lzma/xz support).

Merge r687-689,691,693-701,720 from libarchive.googlecode.com:
Translate getdate.y into C for portability. Make the get_date()
function easier to test as well:
* Have it accept a time_t "now" to use as a reference so that test
code can verify relative time specifications against known starting
points.
* Set up default date after parsing the string so that we
can use the specified timezone (if any) instead of the local
default. Otherwise, local DST makes it almost impossible to
reliably test time specifications such as "sunday UTC"

bsdtar is synced up with 2.5.903a

New command-line parser for bsdtar.

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().

Don't clean before running tests.

FreeBSD-CURRENT bsdtar is synched up with libarchive-portable 2.5.5.

MFp4: bsdtar 2.5.4b

In addition to a number of bug fixes and minor changes:
* --numeric-owner (ignore user/group names on create and extract)
* -S (sparsify files on extraction)
* -s (regex filename substitutions)
* Use new libarchive 'linkify' to get correct hardlink handling for
both old and new cpio formats
* Rework 'copy' test to be insensitive to readdir() filename ordering

Most of the credit for this work goes to Joerg Sonnenberger, who
has been duplicating features from NetBSD's 'pax' program.

Add SIGINFO (and for portability to SIGINFO-lacking systems, SIGUSR1)
handling to bsdtar. When writing archives (including copying via the
@archive directive) a line is output to stderr indicating what is being
done (adding or copying), the path, and how far through the file we are;
extracting currently does not report progress within each file, but
this is likely to happen eventually.

* Most header inclusions are now protected (portability)

Extended attribute support on write for Linux; FreeBSD hooks are
forthcoming. This commit also has a number of style(9) fixes and
minor corrections so the code works better with the build system being
used for non-FreeBSD builds.

Many thanks to: Jaakko Heinonen, who proposed a mechanism for extended
attribute support and implemented both the machine-independent portion
and the Linux-specific portion.

Remove configure.ac.in and the 'distfile' target from
the FreeBSD makefile. This is a step towards cleaning
out the non-FreeBSD bits from the FreeBSD source tree.

Clarify some error messages.

bsdtar now uses the "tree" package instead of "fts" for walking
directory heirarchies.

Support path-rewriting options (including --strip-components) for both
extraction and creation. While I'm here, fix a bug reported by Garrett
Wollman: when stripping the leading '/' from the path "/", don't produce
an entry with an empty name; produce "." instead.

Re-unbreak the distfile target.

Also, reduce the WARNS level to 5 since different build environments
end up using different Yacc skeletons. The BSD one does not
predeclare yyparse, the FSF one does, so it's not really possible to
consistently enforce both -Wmissing-prototypes and -Wredundant-decls.

"make depend" with .y files is trickier than it looks. <sigh>

Add --newer-ctime, --newer-mtime, --newer-ctime-than, and --newer-mtime-than

authors of the public-domain getdate.y date-parsing code.

Portability: the included fts.c should now
compile on many non-FreeBSD systems, including
Linux, Solaris, Darwin, etc.

Use a relative symlinking so that "tar" also works in /stand.

Correct error handling on failed writes
to the archive.

gtar uses -F for another purpose, so bsdtar no longer treats it as a
synonym for --format. Update the man page to reflect this. While
I'm here, change the man page to document "tar" rather than "bsdtar,"
update some comments about -l compatibility and fix a few grammar nits.

Add --totals option. Unlike gtar, this reports the bytes actually
written to the archive, not the ones written to the compressor.
For uncompressed archives, these numbers are the same, of course.

Add "make distfile" capabilities to bsdtar, including informational
COPYING file and some conditional compilation cleanups.

Add a --version option to bsdtar that prints the versions of
both bsdtar and libarchive. Of course, this requires that bsdtar
have a version number. Let's call this 1.00, shall we? ;-)

Make bsdtar the default system tar. This makes /usr/bin/tar a symlink
pointing to /usr/bin/bsdtar by default. To make it point to /usr/bin/gtar,
you can define WITH_GTAR.

Oops. Forced commit to document that the previous commit
also included a Makefile change: use a symlink
/usr/bin/tar -> /usr/bin/bsdtar rather than a hardlink so that
people can more easily tell which tar they're currently using.

Pointy hat: sticky bit 't' or 'T' is shown over IXOTH bit, not IXGRP. <sigh>

Allow brave souls to install bsdtar as the
default "tar" command by defining WITH_BSDTAR.

Note: "gtar" and "bsdtar" commands both exist regardless.

Generally clean up Makefile, remove dmalloc references from source
