k5unseal.c (kg_unseal): Clean up lint warnings

k5unseal.c (kg_unseal):  Clean up lint warnings

accept_sec_context.c (krb5_gss_accept_sec_context): Don't return an
	error token if we can't provide the server name to the KRB5 error
	structure (because cred isn't initialized).

gssapi_krb5.c, gssapi_krb5.h: Export the oid of static arrays as
	krb5_gss_oid_array since it's needed by gss_import_sec_context.

import_sec_context.c: Fix up the OID of the mechanism in the imported
	security context so that we use the static OID if at all possible.
	This is needed since gss_inquire_context() must return a static OID.
