f124826e0d Merge Michihiro NAKAJIMA's significant work on the ISO9660 reader
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

84b1d75646 If we're linking against liblzma, allow the decompressor to use up to
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.

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.

466017cf76 Fiz /usr/bin/unzip: A bug deep in libarchive's read-ahead logic
(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.

fb1db28b6d Partially revert r191171, which went too far in trying
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.

04e8ac36ab Document the liblzma support.
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.
