JavaCVS client library

Hi all,

Issue #33692 is resolved - the cvs client library is built as an autoload
module and it is a part of the projects build. Any module can now have a
dependency on the library.

All issues that are submitted for the library have now "library" subcomponent.
These issues will most likely be resolved in NB 4.0, the library will be
actively used by the cvs profile under vcsgeneric module.

The rest of the module (javacvs/src) will likely not be maintained much and it
will not work in the projects builds due to incompatible changes there (mainly
UI and architectural changes).

The changelog sub-module will hopefully be rewritten to plug into the cvs
profile (issue #34499).

Regards,
Martin
