58efb33976 If we can't stat a file, return the correct ARCHIVE_FAILED (this entry can't 
be processed any further) and a suitable error string.
In particular, this improves the error-reporting when cpio -o is
given a nonexistent filename.

daaf575910 Build lib/ with WARNS=6 by default. 
Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

8088bef24c UU decoder. Now that libarchive can recursively taste input streams, 
you can do things like this:  tar xvf archive.tar.gz.uu

0a1d787383 A raft of test changes and improvements from the Googlecode repository. 
In particular, this includes tests for the new features I've merged
over the last few days.

f124826e0d Merge Michihiro NAKAJIMA's significant work on the ISO9660 reader 
from googlecode:
 * Support for zisofs compressed entries
 * Support for relocated deep directories
 * Direct calculation of link counts for accurate nlink values
   even on images that lack Rockridge extensions
 * Faster handling of the internal file lists.
 * Better detection of ISO variants

87a571f88a Essentially eliminate problems with false hardlinks in POSIX cpio 
archives by generating synthetic ino values and mapping values
from disk into the new values.

b1657eb07c Zip write support for libarchive. 
The initial implementation was developed by Anselm Strauss as part of
Google Summer of Code 2008, then completed by Joerg Sonnenberger.

84b1d75646 If we're linking against liblzma, allow the decompressor to use up to 
1<<30 bytes of memory, which is required for some streams.

Also, try to make the taster more discriminating about raw lzma streams.
The detection here is still really weak, though; please use xz instead
of lzma.

7f16f13149 Be a little more skeptical of dev/ino matches when reading cpio files. 
This eliminates some false-positives in the hardlink detection logic.

023a748ef3 Style and portability fixes for pax writer. Mostly very routine, except for:

bb8a41af51 Various fixes when creating objects on disk: 
* Write xattrs last instead of first (required on platforms that use
   system xattrs for security attributes)
 * Better handling of chdir() failures
 * Don't bother trying to shorten files via seek()/write()
 * Fix build on systems that lack link()/symlink()/mknod()
 * Prefer futimens()/utimensat() when they're present
