Add new man pages for livesys and voldump. Fix the man page for sys to say
what it actually does, rather than implying that it works like livesys, and
to recommend livesys instead. Fix a path error in the NetInfo
documentation. Update the README for the current status, including
listing all installed commands that don't have man pages. (There may still
be some subcommands that don't have man pages but aren't listed.)

This completes the first editing pass of the man pages. Very little
content editing has been done, but the server and client versions of
various man pages have been combined into a single man page for the
file (affects CellServDB, ThisCell, NetInfo, and NetRestrict), the
descriptions of the various AFS cache files have been combined into one
afs_cache man page, and the descriptions of the two butc log files have
been combined into one butc_logs man page.
For man pages for databases with two files, symlinks are now created on
installation for the secondary file name.
All of the man pages should now be ready for public review, additional
editing and cleanup, and content editing.
