Subject: [PATCH 1/2] Switch to use standard GSSAPI by default
Make libgssglue configurable still but disabled by default.
There is no reason to use libgssglue anymore, and modern gssapi
supports all needed features for libtirpc and its dependencies.

Subject: [PATCH 2/2] gss: Fix private data giveaway
When the private data is given away the gss context also needs to go,
because the caller may destroy it, such as when the context is exported
into a lucid context to hand it to the kernel.
