Peter Wemm b05543098c Import CVS-1.6.3-951211.. Basically, this is the cvs-1.6.2 release
plus a couple of minor changes..  

Some highlights of the new stuff that was not in the old version:
 - remote access support.. full checkout/commit/log/etc..
 - much improved dead file support..
 - speed improvements
 - better $CVSROOT handling
 - $Name$ support
 - support for a "cvsadmin" group to cut down rampant use of "cvs admin -o"
 - safer setuid/setgid support
 - many bugs fixed.. :-)
 - probably some new ones.. :-(
 - more that I cannot remember offhand..
