Rearranged headers to reduce duplication and remove local header references from fko.h. Removed references to headers that did not need to be explicitly set. Moved the MAX_PROTO_STR_LEN and MAX_PORT_STR_LEN definitions to the fko_limits.h file. Fixed bug where invalid nat_access or command messages were returning FKO_ERROR_INVALID_SPA_ACCESS_MSG error code instead of the one appropriate to the message type. Fixed bad nat_access_msg test in Perl module test suite (caught by new validation code).
