The pam_krb5 module stored a reference to a krb5_ccache structure as
PAM module state (created in pam_sm_authenticate and referenced later
in pam_sm_setcred and pam_sm_acct_mgmt).  However, the krb5_ccache
structure shares some data members with the krb5_context structure
that was used in its creation.  Since a new krb5_context is created
and destroyed at each PAM entry point, this inevitably caused the
krb5_ccache structure to reference free'd memory.

Now instead of storing a pointer to the krb5_ccache structure,
we store the name of the cache (e.g. `MEMORY:0x123CACHE') in
pam_sm_authenticate, and resolve the name in the other entry points.

This bug was uncovered by phkmalloc's free'd memory scrubbing.
