exercises and verifies the libarchive APIs:
* Improved error reporting; hexdumps are now provided for
many file/memory content differences.
* Overall status more clearly counts "tests" and "assertions"
* Reference files can now be stored on disk instead of having
to be compiled into the test program itself. A couple of
tests have been converted to this more natural structure.
* Several memory leaks corrected so that leaks within libarchive
itself can be more easily detected and diagnosed.
* New test: GNU tar compatibility
* New test: Zip compatibility
* New test: Zero-byte writes to a compressed archive entry
* New test: archive_entry_strmode() format verification
* New test: mtree reader
* New test: write/read of large (2G - 1TB) entries to tar archives
(thanks to recent performance work, this test only requires a few seconds)
* New test: detailed format verification of cpio odc and newc writers
* Many minor additions/improvements to existing tests as well.
GNU tar 1.17's implementation of --posix --sparse,
at the cost of losing compatibility with GNU tar 1.16.
Fortunately, the 1.17 implementation actually makes sense,
so the libarchive code is now a bit more straightforward
than before.
Background: GNU tar 1.16 defined a new way to store
sparse files in --posix archives. Unfortunately,
the implementation incorrectly inserted several
blocks of null padding after each such entry.
As a result, non-GNU tar implementations saw the
archive as truncated after any sparse entry.
This was fixed in GNU tar 1.17 at the cost of
losing compatibility with GNU tar 1.16 for this
new format (which is not the default, so hopefully
rarely used). Libarchive recently gained support
for reading the GNU tar 1.16 formats; this commit
updates it to read the GNU tar 1.17 variant instead.

In particular:
* Include a second entry in all of the test archives (to catch errors
with intermediate padding)
* Test the GNU tar 1.17 version of "posix sparse format 1.0"
instead of the GNU tar 1.16 version (the latter is no longer
supported by GNU tar).
Right now, libarchive fails this test because I originally
implemented the GNU tar 1.16 version of "posix sparse format 1.0".
I'll fix libarchive shortly.

it now verifies that the returned blocks have the correct data
at the correct file offsets, ignoring any null padding that
may exist.
Approved by: re (blanket, libarchive test suite)
ARCHIVE_VERSION_STAMP to selectively disable tests that don't
apply to that version; new "skipping()" function reports skipped
tests; modify final summary to report component test failures and
skips.
Note: I don't currently intend to MFC the test suite itself;
anyone interested should just checkout and use this version
of the test suite, which should work for any library version.
