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.

3730:
Fix issue 174 (Windows path names, not relevant for FreeBSD)
3734:
Merge r1989: archive_clear_error should set errno to 0.
3735:
Merge r3247 from trunk: Clear errors before returning
from archive_read_support_format_all()
3799:
Check the position before dereferencing the pointer.
This avoids dereferencing one byte past the end of a string
3824:
Merge r3823 from trunk for issue 199 (hang in iso9660 reading)

The following additional vendor revisions are applied:
Revision 3740:
Use archive_clear_error() to clear the error markers.

MFC after: 2 weeks
Fixes extraction of Zip entries that use length-at-end without specifying
either the compressed or uncompressed length. In particular, fixes bsdtar
extraction of such files.

ISO images with tar.
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.

Partial merge of 2431 from trunk: Retry writes on EINTR.
This should fix the SIGINT handler in bsdtar.
Note: The rest of r2431 can't be merged, since it interacts
with a big write-side rearchitecture.

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.
Revision 3484:
Use uintmax_t with %ju
Revision 3487:
Fix issue 163.
Correctly allocate enough memory for a input buffer saved.

because there's inter-entry garbage, just scan forward
to find the next one. This allows us to handle a lot
of Zip archives that have been modified in-place.
Thanks to: Gleb Kurtsou for sending me a sample archive
bottom of the manpages and order them consistently.
GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

Adjust dependencies for programs using libarchive

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.
from googlecode:
* Support for zisofs compressed entries
* Support for relocated deep directories
* Direct calculation of link counts for accurate nlink values
even on images that lack Rockridge extensions
* 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.
