63165a380d Fix the copyright notice; it was always intended to be
a vanilla 2-clause BSD license, but somehow some confusing
extra verbage get copied from somewhere.

Also, update the copyright dates to 2007 for all of the files.

Prompted by: several questions about what those extra words really mean

85af60729f Don't mention 'pax' in the context of POSIX-1988, since
pax wasn't introduced until the 1993 (?) revision.

(I need to double-check when pax was introduced and
clarify some of the history here.  In particular,
I should explain that the 'pax' standard now owns the
'ustar' format spec.)

2228e32755 POSIX.1e-style Extended Attribute support
This commit implements storing/reading POSIX.1e-style extended
attribute information in "pax" format archives.  An outline of the
storage format is in the tar.5 manpage.  The archive_read_extract()
function has code to restore those archives to disk for Linux; FreeBSD
implementation is forthcoming.

Many thanks to Jaakko Heinonen for finding flaws in earlier
proposals and doing the bulk of the coding in this work.

b2d9ea9fd3 Having implemented read support for it, I now know how to document the
GNU sparse file extension.

ecad688385 I've recently been looking at the Seventh Edition source
code available at tuhs.org, and found out that my chronology
is a bit off.  In particular, Seventh Edition already used
the "linkflag" and "linkname" fields.  Also, it appears that
there was no tar in Sixth Edition, contrary to what an earlier
tar.1 manpage claimed.

A few mdoc fixes also crept in here.

44a3d34206 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>

2710e4d1ef Initial import of libarchive.
What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.
