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.

Vendor revision 3648 (merge of 3647):
Additional fix to issue 168 because the change of r3642 was not sufficient.
- Make sure "CL" entry appear after its "RE" entry which the "CL" entry
should be connected with.
- Give consideration to the case that the top level "RE" entry has
already been exposed outside before its tree.

Upstream revision 3645 (merge of 3642):
Change the mechanism handling a rr_moved directory,
which is Rockridge extension that can exceed the limitation of
a maximum directory depth of ISO 9660.
- Stop reading all entries at a time.
- Connect "CL" entry to "RE" entry dynamically, which "CL" and "RE"
have information to rebuild a full directory tree.
- Tweak some related tests since we use Headsort for re-ordering
entries and it cannot make a steady order when the keies of
the entries are the same.

violated ECMA-119 (ISO9660): allow reserved4 to be 0x20 in PVD.
This allows tar to read FreeBSD distribution ISO images created
with makefs prior to NetBSD bin/45217 bugfix (up to 9.0-BETA1).
In addition, merge following important bugfixes from
libarchive's release/2.8 branch:
Revision 2812:
Merge 2811 from trunk: Don't try to verify that compression-level=0
produces larger results than the default compression, since this isn't
true for all versions of liblzma.
Revision 2817:
Merge 2814 from trunk: Fix Issue 121 (mtree parser error)
http://code.google.com/p/libarchive/issues/detail?id=121
Revision 2820:
Fix issue 119.
Change the file location check that a file location does not exceed
volume block. New one is that a file content does not exceed volume
block(end of an ISO image). It is better than previous check even
if the issue did not happen.
While reading an ISO image generated by an older version of mkisofs
utility, a file location indicates the end the ISO image if its file
size is zero and it is the last file of all files of the ISO image,
so it is possible that the location value is the same as the number
of the total block of the ISO image.

Revision 2955:
Issue 134: Fix libarchive 2.8 crashing in archive_write_finish() when
the open has failed and we're trying to write Zip format.
http://code.google.com/p/libarchive/issues/detail?id=134
Revision 2958:
Followup on Issue 134:
1) Port test_open_failure to libarchive 2.8 branch to test
the problem reported in Issue 134.
This test also shows that archive_read_open() sometimes
fails to report open errors correctly.
2) Fix the bug in archive_read.c
3) Comment out the tests that close functions are invoked
promptly when open fails; that's fully fixed in libarchive 3.0,
but I don't think it's worth fixing here.

Adjust dependencies for programs using libarchive
Add xz and linkage against liblzma to rescue system
Approved by: kientzle, delphij (mentor)

Instead of trying to reference-count them and free them as soon
as they are no longer needed, we now just keep them around and free
them all when we release the archive object. This fixes a number
of minor memory leaks, especially when reading damaged archives.
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.
I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

* Support for relocated deep directories
* Direct calculation of link counts for accurate nlink values

* Faster handling of the internal file lists.
* Better detection of ISO variants
1<<30 bytes of memory, which is required for some streams.
Also, try to make the taster more discriminating about raw lzma streams.
The detection here is still really weak, though; please use xz instead
of lzma.
* Write xattrs last instead of first (required on platforms that use
system xattrs for security attributes)
* Better handling of chdir() failures
* Don't bother trying to shorten files via seek()/write()
* Fix build on systems that lack link()/symlink()/mknod()
* Prefer futimens()/utimensat() when they're present
* Enforce option interface can only be used before the archive is opened
* Correctly handle large skips on platforms with 32-bit off_t
* Use int64_t instead of off_t
1) Avoid an infinite loop in the header resync for certain malformed
archives.
2) Don't try to match hardlinks if the nlinks count is < 2. This
reduces the likelihood of a false hardlink match due to ino truncation.

to eliminate some duplicated code. In particular,
archive_read_open_filename() has different close
handling than archive_read_open_fd(), so delegating
the former to the latter in the degenerate case
(a NULL filename is treated as stdin) broke reading
from pipelines. In particular, this fixes occasional
port failures that were seen when using "gunzip | tar"
pipelines under /bin/csh.
Thanks to Alexey Shuvaev for reporting this failure and
patiently helping me to track down the cause.
Unfortunately, liblzma itself is GPLed, so unlikely to become part of
the FreeBSD base system.
However, the core lzma compression/decompression code is public
domain, so it should be feasible for someone to create a compatible
library without the GPL strings.
read_support_format_raw() allows people to exploit libarchive's
automatic decompression support by simply stubbing out the
archive format handler.
The raw handler is not enabled by support_format_all(), of course.
It bids 1 on any non-empty input and always returns a single
entry named "data" with no properties set.

In particular, this fixes the following idiom for creating
a tar archive in which every file is owned by root:

Not an issue for FreeBSD, since the base system has the necessary libraries.
Since all decompressors are always available now, we can unconditionally
enable them in archive_read_support_compression_all().
Since FreeBSD doesn't have liblzma in the base system, the
read side will always fall back to the unxz/unlzma commands for now.
(Which will in turn fail if those commands are not currently
installed.) The write side does not yet have a fallback, so
that will just fail.
fixes to read_support_compression_program. In particular, failure of
the external program is detected a lot earlier, which gives much more
reasonable error handling.
