0260ab4f4e Split the append_archive function (used for processing @<archive> directives)
into separate append_archive and append_archive_filename functions; the first
takes a "struct archive *" as input, while the second takes a filename, opens
the archive, and calls the first.

There should be no changes in behaviour as a result of this commit; it simply
reorganizes code to make more sense.  At some point in the future it may be
possible to share code between append_archive and read_archive, but not yet.

486641fcc5 Fix logic bug; we want to do_chdir if arg doesn't start with / _and_ it
doesn't start with @/ either.

This unbreaks "tar -c -C /no/such/directory @/path/to/archive".

5e85b65e97 Don't consider an lstat(2) failure to be an error (in the sense of
affecting the return value from bsdtar), since (a) it usually occurs
due to a perfectly innocent (and unavoidable) race condition where a
user deletes a file in the window between bsdtar reading a directory
and attempting to read the file; and (b) aside from printing a warning
message, bsdtar behaves exactly as if the file had been deleted prior
to bsdtar reading its parent directory.

4d41b13b4e Reduce the risk of inducing heart attacks, by printing the right path when
complaining about lstat(2) failing.  It's a bit scary to find the message
  tar: /: Cannot stat: No such file or directory
printed while doing a backup.

1267d00111 Clarify the test comments in test-basic.sh. Have config.sh do a
better job searching for the bsdtar binary to test and the gtar binary
to use for inter-operability testing.  It should now find the built
(but not installed) binary if there is one, then search for an
installed binary in a number of standard locations.

45d4d7ac8c bsdtar 2.0.23:
* New test scripts exercise some basic functionality
   * Most header inclusions are now protected (portability)
   * read.c now relies on security checks in libarchive instead
     of trying to do its own (optimization)
   * -p now enabled by default for root, add --no-same-permissions
     to disable it
   * Comments, minor style fixes.

254cbd1764 Argh. Support for reading ACLs off of disk was inadvertently disabled
as part of an old configuration shuffle.  As a result, although
ACL restore has been working, ACLs haven't been written into archives
for some time.  <sigh>

effb1b7fcb Correctly handle writes beyond the end of the archive entry
(as determined by the initial size given to the header).
Libarchive recently changed to correctly return the amount
of data actually consumed in this case, which revealed this
bug in bsdtar.

minor corrections so the code works better with the build system being
used for non-FreeBSD builds.

Many thanks to: Jaakko Heinonen, who proposed a mechanism for extended
attribute support and implemented both the machine-independent portion
and the Linux-specific portion.

d12dff713a If opendir(".") fails after descending into a subdirectory via
chdir(), be sure to undo the effects of the chdir before continuing.

Without this, after hitting a directory with mode 0111 (for example),
tar will get lost, and won't add any yet unvisted files to your
archive.  (Or possibly add the wrong files, I suppose...)
