Constify string for authorization protocol names

gcc was warning from storing string constants in a char *name field:
auth.c:64:1: warning: initialization discards qualifiers from pointer target type
auth.c:72:1: warning: initialization discards qualifiers from pointer target type
auth.c:81:1: warning: initialization discards qualifiers from pointer target type

Making the field const requires changing AuthorizationFromID to take
a const char ** pointer for the name argument which it sets to point
to the matching name entry.

Changing that argument requires changing its sole caller in the security
extension to pass the address of a const char * variable to it, which it
can do, since the only thing it does with the returned name is to pass
it back to the RemoveAuthorization function that already expects a const
char *name.
