configure: check for some more krb5 functions

We will want to create a krb5_principal object that is used
as a sigil for comparison against, and need to do so in a portable
fashion.  krb5_parse_name and krb5_unparse_name have been around
for a long time, but the counterpart krb5_free_unparsed_name is
not always available, so provide compatibility for it.

krb5_free_keytab_entry_contents is only a symbol in MIT krb5;
we will need a compat macro on Heimdal systems where it is not present.
