New buildfarm client release

I have just released version 4.0 of the PostgreSQL Buildfarm client.

There are two new features:

* The SCM code is substantially rearranged into a separate OO
module, with subclasses supporting CVS and Git. New config options
support these changes, while old style config parameters for CVS
are still supported. Support for running the buildfarm from Git is
a requirement before we can move the core community repo, and this
meets that requirement (a little later than planned, but as
promised almost exactly one year ago).
* The requirement to specify a port for each branch to build with is
gone. If the config parameter 'base_port' is specified the code
will pick a unique port for the branch, a short number above that
setting. The means that the config file does not need to be
changed when a new stable postgres release is made. Again,
old-style configs continue to be supported.

The new client can be downloaded from:
