bb7c5fa31c Don't write data into an empty "file." 
In particular, this check avoids a warning when
extracting directory entries from certain GNU tar
archives that store directory contents.

f408e1d38d If the Zip reader doesn't see a PK signature block 
because there's inter-entry garbage, just scan forward
to find the next one.  This allows us to handle a lot
of Zip archives that have been modified in-place.

Thanks to: Gleb Kurtsou for sending me a sample archive

0afc94c17a mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the 
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

This does not change any WARNS level and survives a make universe.

54d2369731 Use a simpler memory-management strategy for the file objects. 
Instead of trying to reference-count them and free them as soon
as they are no longer needed, we now just keep them around and free
them all when we release the archive object.  This fixes a number
of minor memory leaks, especially when reading damaged archives.

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.

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

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.
