c8ffa65148 Flush input when reading from pipe to avoid "broken pipe" warnings.
For example, when using 'gunzip | tar' to decompress.
Also, fix some style issues (write null character as '\0').

Thanks to: Jaakko Heinonen

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.
