d3b6573b00 Simplify some of the wide-character handling, inspired
in part by OpenBSD's not-quite-standard-compliant
standard libraries.  (No loss of functionality,
just minor recoding to not rely on certain "standard"
facilities that weren't actually needed.)

542f05ce07 Even if a system does not support restoring extended attributes,
it's only a failure if there were actually attributes to be restored.
In particular, this fixes the problem where tar -xp always returned
a failure code on FreeBSD (which doesn't yet have all of the extended
attribute support).

Thanks to: Diego "Flameeyes" Petteno

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.

bbadd8d88d The idea of supporting 'tp' was a fun one, but it is
really not worth the effort to develop and maintain
support for a format that hasn't been used for 30 years. ;-/

752ede3058 If the attempt to open the archive fails (either the client open
routine fails or the first read fails), invoke the client close
routine immediately so the client can clean up.  Also, don't store the
client pointers in this case, so that the client close routine can't
accidentally get called more than once.

A minor style fix to archive_read_open_fd.c while I'm here.

bbf3318c61 Add support for "tp" format. tp was the standard system
archiver for Fourth Edition through Sixth Edition Unix; it was
replaced by tar in Seventh Edition.  (First Edition through
Third Edition used "tap.")

Unfortunately, tp was not so very standard; there were a
few different variants.  The code here attempts to support
what I believe were the most common variants.

tp support is not yet enabled by archive_read_support_format_all(),
as I'm not yet entirely comfortable with the detection
heuristics.  People interested in experimenting can
add archive_read_support_format_tp() just after any calls
to archive_read_support_format_all() in bsdtar to see how
well this works.

TODO: tp format is roughly similar in structure to dump/restore
   archive formats used by many systems.  It should be possible
   to generalize this code to handle many dump/restore variants.
   Format detection heuristics are going to be rough, though.

Thanks to: Warren Toomey, whose very basic tp extraction programs
   and documentation made this possible.

55be5837f8 Portability: Remove AC_CHECK_MALLOC from configure.ac.in.
libarchive doesn't make malloc(0) requests, so the autoconf
checks aren't needed and the autoconf workarounds for
broken malloc(0) just create problems.

db38abe649 1) Use GNU libtool to build shared libraries on non-FreeBSD
systems (or on FreeBSD systems when using ports).

2) Overhaul the versioning logic.  In particular,
   SHLIB_MAJOR number is now computed as "major+minor",
   which ensures library versions are the same for
   the FreeBSD build system and the portable
   libtool/autoconf/automake build system.

52a88d3b57 In pax interchange format, use UTF8 for writing
link names, usernames, or group names that contain
non-ASCII characters.

In particular, this corrects an inconsistency reported
by Ed Maste when archiving symlinks with odd characters:
long symlinks would get preserved, short ones would
be changed.

3be7274eed In archive_read_open(), do not set the internal archive state to
"HEADER" unless the open is successful.  Instead, leave the state as
"NEW."  In particular, if archive_read_open() fails, a subsequent call
to archive_read_next_header() will now cause an explicit assertion
failure instead of a silent segmentation fault.

This may need a little more work to fully realize the intention: If
archive_read_open() fails, you should be able to call it again on the
same archive handle to open a different archive (or the same archive
using a different mechanism).

1dd0aa0c18 Style issue: Don't include <wchar.h> where it is not actually needed.
(wchar_t is defined in stddef.h, and only two files need more than that.)

Portability:  Since the wchar requirements are really quite modest,
it's easy to define basic replacements for wcslen, wcscmp, wcscpy,
etc, for use on systems that lack <wchar.h>.  In particular, this allows
libarchive to be used on older OpenBSD systems.

01122e2ae0 Generate default fake "device" and "inode" numbers for entries
extracted from tar archives.  Otherwise, converting tar archives to
cpio format (with "bsdtar -cf out.cpio @in.tar") convert every entry
into a hard link to a single file.  This simple logic breaks hard
links, but that's better than the alternative.
