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.
unspecified size are "unlimited" (required by Zip reader, which
sometimes does not know the uncompressed size of an entry until it
gets to the end). Also, hardlinks with unspecified (or zero) size do
not overwrite the data on disk nor do they set metadata. This is
compatible with GNU tar and NetBSD pax behavior.
Even though I believe this is a good change, it does
have the potential to break certain clients, so it's
good to document the reasoning behind the change.
number of bytes written, even when used to write files to
disk. Extend the test suite to verify the correct return
values for archive_write_data() and archive_write_data_block().

* The documentation
* The return values of this function when used
to write files into an archive.

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.

* "compression_program" support uses an external program
* Portability: no longer uses "struct stat" as a primary
data interchange structure internally
* 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

Thanks to: Many others who sent me various patches and problem reports.
* 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.
