4e782d8fc0 Refuse to extract an entry from an archive on top of the archive being read.
(This is the converse of the "don't add an archive to itself".)

5c2c79eafd * Plug a buffer overrun in ACL parsing. (archive_entry.c)
* Re-use a single buffer for shar output formatting rather
   than hammering the heap. (archive_write_set_format_shar.c)
 * Fix a handful of minor memory leaks and clean up some of the
   memory-management code.

444807bb41 More work on ACLs: fix error in archive_entry's ACL parsing code,
try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files

775d07093e Overhauled ACL support. This makes us compatible
with 'star' ACL handling, though there's still a
bit more work needed in this area.

Added 'write_open_fd' and 'read_open_fd' to simplify, e.g.,
tar's u and r modes.  Eliminated old 'write_open_file_position'
as a bad idea.  (It required closing/reopening files to
do updates, which led to unpleasant implications.)

Various other minor fixes, API tweaks, etc.

90072dfae0 Many fixes.
Portability: Thanks to Juergen Lock, libarchive now compiles cleanly
on Linux.  Along the way, I cleaned up a lot of error return codes and
reorganized some code to simplify conditional compilation of certain
sections.

Bug fixes:
  * pax format now actually stores filenames that are 101-154
    characters long.
  * pax format now allows newline characters in extended attributes
    (this fixes a long-standing bug in ACL handling)
  * mtime/atime are now restored for directories
  * directory list is now sorted prior to fix-up to permit
    correct restore of non-writable dir heirarchies

af9413b539 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.
