Support host-based GSS initiator names
When checking if we can get initial credentials in the GSS krb5 mech,
use krb5_kt_have_match() to support fallback iteration. When scanning
the ccache or getting initial credentials, rewrite cred->name->princ
to the canonical client name. When a name check is necessary (such as
when the caller specifies both a name and ccache), use a new internal
API k5_sname_compare() to support fallback iteration. Add fallback
iteration to krb5_cc_cache_match() to allow host-based names to be
canonicalized against the cache collection.
Create and store the matching principal for acceptor names in
acquire_accept_cred() so that it isn't affected by changes in
cred->name->princ during acquire_init_cred().
