Many fixes:

* Disabled shared-library building, as some API breakage is
  still likely.  (I didn't realize it was turned on by default.)  If
  you have an existing /usr/lib/libarchive.so.2, I recommend deleting it.
* Pax interchange format now correctly stores and reads UTF8
  for extended attributes.  In particular, pax format can portably
  handle arbitrarily long pathnames containing arbitrary characters.
* Library compiles cleanly at -O2, -O3, and WARNS=6 on all
  FreeBSD-CURRENT platforms.
* Minor portability improvements inspired by Juergen Lock
  and Greg Lewis.  (Less reliance on stdint.h, isolating of
  various portability-challenged constructs.)
* archive_entry transparently converts multi-byte <-> wide character
  strings, allowing clients and format handlers to deal with either
  one, as appropriate.
* Support for reading 'L' and 'K' entries in standard tar archives
  for star compatibility.
* Recognize (but don't yet handle) ACL entries from Solaris tar.
* Pushed format-specific data for format readers down into
  format-specific storage and out of library-global storage.  This
  should make it easier to maintain individual formats without mucking
  with the core library management.
* Documentation updates to track the above changes.
* Updates to tar.5 to correct a few mistakes and add some additional
  information about GNU tar and Solaris tar formats.

Notes:
* The basic 'tar' reader is getting more general; there's not much
  point in keeping the 'gnutar' reader separate.  Merging the two
  would lose a bunch of duplicate code.
* The libc ACL support is looking increasingly inadequate for my needs
  here.  I might need to assemble some fairly significant code for
  parsing and building ACLs. <sigh>
