Change of catalog name for Curl

Dear users,

the catalog names for the Curl packages have been adjusted to
conform to the OpenCSW standard. That is:

* CSWcurlrt
   - Old catalog name: curlrt
   - New catalog name: curl_rt

* CSWcurldevel
   - Old catalog name: curldevel
   - New catalog name: curl_devel

Please note that this only affects new installation with pkg-get and
pkgutil as the package name used for dependencies is not affected.

Kind regards
