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.

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

MFC after: 2 weeks
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.
Revision 3484:
Use uintmax_t with %ju
Revision 3487:
Fix issue 163.
Correctly allocate enough memory for a input buffer saved.

In particular, this check avoids a warning when
extracting directory entries from certain GNU tar
archives that store directory contents.

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
(incorrect handling of zero-length reads before the copy buffer is
allocated) is masked by the iso9660 taster. Tar and cpio both enable
that taster so were protected from the bug; unzip is susceptible.
This both fixes the bug and updates the test harness to exercise
this case.

on iso9660 images were returned. While I'm poking around, update
some comments around this area to try to clarify what's going on and
what still remains to be improved.
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.
Fix reading big-endian binary cpio archives, and add a test.
While I'm here, add a note about Solaris ACL extension for cpio,
which should be relatively straightforward to support.
Thanks to: Edward Napierala, who sent me a big-endian cpio archive
from a Solaris system he's been playing with.
Pointy hat: me
Make test_fuzz a bit more sensitive by actually reading the body
of each entry instead of skipping it.
While I'm here, move the "UnsupportedCompress" macro into the
only file that still uses it.
* Fix parsing of POSIX.1e ACLs from Solaris tar archives
* Test the above
* Preserve the order of POSIX.1e ACL entries
* Update tests whose results depended on the order of ACL entries
* Identify NFSv4 ACLs in Solaris tar archives and warn that
they're not yet supported. (In particular, don't try to parse
them as POSIX.1e ACLs.)
Thanks to: Edward Napierala sent me some Solaris 10 tar archives to test
access to the file data (if the file exists on
disk). This was broken for the first regular
file; fix it and add a test so it won't break again.
In particular, this fixes the following idiom for creating
a tar archive in which every file is owned by root:
tar cf - --format=mtree . \
| sed -e 's/uname=[a-z]*/uname=root/' -e 's/uid=[0-9]*/uid=0/' \
| tar cf - @-
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.
corrections to the Windows support to reconcile differences
between Visual Studio and Cygwin. Includes parts of
revisions 757, 774, 787, 815, 817, 819, 820, 844, and 886.
Of particular note, r886 overhauled the UTF-8/Unicode conversions to
work correctly regardless of whether the local system uses 16-bit
or 32-bit wchar_t. (I assume that systems with 16-bit wchar_t
use UTF-16 and those with 32-bit wchar_t use UCS-4.) This revision
also added a preference for wcrtomb() (which is thread-safe) on
platforms that support it.
conditioning tests on HAVE_ZLIB, etc, just ask libarchive for the
service and handle the failure coming back from libarchive. This
gives us better test coverage of common client usage where clients
simply try to use libarchive services and handle the errors coming
back instead of trying to second-guess which libarchive services are
compiled in.
Support Joliet extensions. This currently ignores Rockridge extensions
if both exist on the same disk unless the '!joliet' option is provided.
e.g.: tar -xvf example.iso --options '!joliet'

as the compression name when no other read filter bid. Add some
assertions to various tests to verify that read filters are properly
setting the textual name as well as the compression code.
Restoring POSIX.1e Extended Attributes on FreeBSD, part 1
This implements the basic ability to restore extended attributes
on FreeBSD, including a test suite.
from libarchive.googlecode.com: Add a new "archive_read_disk" API
that provides the important service of reading metadata from the
disk. In particular, this will make it possible to remove all
knowledge of extended attributes, ACLs, etc, from clients such
as bsdtar and bsdcpio.
Closely related, this API also provides pluggable uid->uname
and gid->gname lookup and caching services similar to
the uname->uid and gname->gid services provided by archive_write_disk.
Remember this is also required for correct ACL management.
Documentation is still pending...
into the debugger on test setup failures (otherwise, the console window
just goes away and you can't see what went wrong). On all platforms,
clean up a stray buffer before exiting.
This is the last phase of the "big decompression refactor" that
puts a lazy reblocking layer between each pair of read filters.
I've also changed the terminology for this area---the two kinds
of objects are now called "read filters" and "read filter bidders"---and
moved ownership of these objects to the archive_read core.
This greatly simplifies implementing new read filters, which
can now use peek/consume I/O semantics both for bidding (arbitrary
look-ahead!) and for reading streams (look-ahead simplifies handling
concatenated streams, for instance).
The first merge here is the overhaul proper; the remainder are small
fixes to correct errors in the initial implementation.
locale-based failures on systems where the "C" locale is so permissive
that it cannot possibly fail. In particular, this fixes a test
problem on Cygwin.
