Update libarchive to 2.4.10. This includes a number of improvements
that I've been working on but put off committing until after the
RELENG_7 branch, including:

* New manpages: cpio.5 mtree.5
* New archive_entry_strmode()
* New archive_entry_link_resolver()
* New read support: mtree format
* Internal API change: read format auction only runs once
* Running the auction only once allowed simplifying a lot of bid logic.
* Cpio robustness: search for next header after a sync error
* Support device nodes on ISO9660 images
* Eliminate a lot of unnecessary copies for uncompressed archives
* Corrected handling of new GNU --sparse --posix formats
* Correctly handle a zero-byte write to a compressed archive
* Fixed memory leaks

Many of these improvements were motivated by the upcoming bsdcpio
front-end.

There have also been extensive improvements to the libarchive_test
test harness, which I'll commit separately.

* Part of the above: refactor archive_entry to separate
out copy_stat() and stat() functions
* More complete tests for archive_entry
* Finish archive_entry_clone()
* Isolate major()/minor()/makedev() in archive_entry; remove
these from everywhere else.
* Bug fix: properly handle decompression look-ahead at end-of-data
* Bug fixes to 'ar' support
* Fix memory leak in ZIP reader
* Portability: better timegm() emulation in iso9660 reader
* New write_disk flags to suppress auto dir creation and not
overwrite newer files (for future cpio front-end)
* Simplify trailing-'/' fixup when writing tar and pax
* Test enhancements: fix various compiler warnings, improve
portability, add lots of new tests.
* Documentation: document new functions, first draft of
libarchive_internals.3

Overhaul of 'ar' support:
* use "AR_GNU" as the format name instead of AR_SVR4 (it's what everyone is going to call it anyway)
* Simplify numeric parsing to unsigned (none of the numeric values should ever be negative); don't run off end of numeric fields.
* Finish parsing the common header fields before the next I/O request (which might dump the contents)
* Be smarter about format guessing and trimming filenames.
* Most of the magic values are only used in one place, so just inline them.
* Many more comments.
* Be smarter about handling damaged entries; return something reasonable.
* Call it a "filename table" instead of a "string table"
* Update tests.

Enable selection of 'ar', 'arbsd', and 'argnu' formats by name
(this allows bsdtar to create ar format archives).

The 'ar' writer still needs some work; it should reject
entries that aren't regular files and should probably also
strip leading paths from filenames.

Fix the build by temporarily disabling 'ar' support until
I can clean it up.

Fix the build.
N.B. 'ar' format support is broken right now, it's not
passing tests. If I can't find the problem soon, I'll
back out the last commit.

Conventionally, tar archives have always included a trailing '/'
for directories. bsdtar used to add this, but that recently got
lost somehow. So now I'm adding it back in libarchive.

for directories. bsdtar used to add this, but that recently got
lost somehow. So now I'm adding it back in libarchive.
The only odd part of doing this in libarchive: Adding a directory to
a tar archive and then reading it back again can yield a different name.

Add a test case to exercise some boundary conditions with
tar filenames and ensure that trailing slashes are added to
dir names only as necessary.

Thanks to: Oliver Lehmann for bringing this regression to my attention.

Enable 'ar' support; hook it up to the build and
enable it with _read_support_format_all().

Notice when mkdir() fails.
Don't change permissions on an existing dir unless _EXTRACT_PERM
is requested.

In particular, bsdtar -x should not edit mode of existing dirs
now; bsdtar -xp will.

When ARCHIVE_EXTRACT_UNLINK is requested:
* Only try to remove the existing item if we're not restoring a directory.
* If unlink fails, try rmdir next.
This should fix the broken --unlink option

libarchive 2.0
* libarchive_test program exercises many of the core features
* Refactored old "read_extract" into new "archive_write_disk", which
uses archive_write methods to put entries onto disk. In particular,
you can now use archive_write_disk to create objects on disk
without having an archive available.
* Pushed some security checks from bsdtar down into libarchive, where
they can be better optimized.
* Rearchitected the logic for creating objects on disk to reduce
the number of system calls. Several common cases now use a
minimum number of system calls.
* Virtualized some internal interfaces to provide a clearer separation
of read and write handling and make it simpler to override key
methods.
* New "empty" format reader.
* Corrected return types (this ABI breakage required the "2.0" version bump)
* Many bug fixes.

Write-blocking cleanup, largely thanks to Colin Percival (cperciva@).
* If write block size is zero, don't block at all.
This supports the unusual requirement of applications
that need "no-delay" writes.
* Expose _write_finish_entry() to give such applications more
control over write boundaries. (Normal applications do not
need this, as entries are completed automatically.)
* Correct the type of write callbacks; this is a minor API
change that does not affect the ABI.
* Correct the error handling in _write_next_header() around
completing the previous entry.
* Correct the documentation for block-size markers: Remove
docs for the long-defunct _read_set_block_size(); document
all of the write block size manipulators.

Unbreak libarchive on arm. Two parts of libarchive relied on a
traditional shortcut of defining on-disk layouts using structures of
character arrays. Unfortunately, as recently discussed on cvs-all@,
this usage is not actually sanctioned by the standards and
specifically fails on GCC/arm (unless your data structures happen to
be "naturally aligned").

The new code defines offsets/sizes for data fields and accesses
them using explicit pointer arithmetic, instead of casting to
a structure and accessing structure fields. In particular,
the new code is now clean with WARNS=6 on arm.
