this commit includes all the changes on the OV_9510_INTEGRATION and
OV_MERGE branches. This includes, but is not limited to, the new openvision
admin system, and major changes to gssapi to add functionality, and bring
the implementation in line with rfc1964. before committing, the
code was built and tested for netbsd and solaris.
