Refactor name caching to use a common piece of code for uname_cache and
...
gname_cache. Cache negative lookups to dramatically improve performance
building archives containing nonexistent uid/gid.

Make symlink protection a bit more useful:
...
* Remove terminal symlinks so they can be replaced.
* If -U, remove intermediate symlinks as well
* Otherwise, refuse the extraction

For portability, don't rely on libc's strmode(3). <sigh>

A security issue: An archive containing a symlink to another
...
directory, then a file with that symlink as a prefix can drop a file
outside of the current directory, which can be a security hole.
Plug this hole by refusing to extract files if a prefix of the
pathname is a symlink. The -P option disables this check.

As suggested by Julian Elischer, use a self-sizing hash
...
table for the hardlink cache. This dramatically improves
performance when archiving millions of hardlinked files.
While I'm here, clean up some style bugs (per Bruce Evans)
and clarify some comments.

A simple cache of uid->uname lookups and gid->gname lookups eliminates
...
almost 1/2 of the CPU time required to create an uncompressed archive
and makes a noticable reduction in wallclock time.
