101c7b294b Remove configure.ac.in and reorganize a few other things. This is
part of a program to remove the non-FreeBSD autoconf/automake build
system for libarchive from the FreeBSD source tree.

d13f81857d 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.

2b45598dea 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.

ed48aeada3 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.

e137eb325c 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.

non-ASCII characters.

In particular, this corrects an inconsistency reported

long symlinks would get preserved, short ones would

0fd9f664d7 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).

9d88c7f7b7 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.

e937b9141e 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.

3c03499e5b Start to address the race issue between restoring a file's contents
and restoring the metadata.  In particular, the metadata-restore
functions now all accept a file descriptor and a pathname.  If the
file descriptor is set and the platform supports the appropriate
syscall, restore the metadata through the file descriptor.  Otherwise,
restore it through the pathname.  This is complicated by varying
syscall support (FreeBSD has an fchmod(2) but no fchflags(2), for
example) and because non-file entries don't have an fd to use in
restoring attributes (for example, mknod(2) doesn't return a file
handle).
