PostgreSQL Buildfarm client release 4.6

I have just released version 4.6 of the PostgreSQL Buildfarm client. It
can be downloaded from:
<https://github.com/downloads/PGBuildFarm/client-code/build-farm-4_6.tgz> Note
that this is NOT on PgFoundry, as it seems to have a rather uncertain
future.

Changes:

* Ability to specify 'ALL' as branches to build in config file,
cueing run_branches.pl to get the actual list of branches of
interest from the server and build all of them. This means
branches can be automatically dropped when they are past end of
life, and new picked up when they are created, without operator
intervention.
* Ability to throttle builds for some or all branches, either by
specifying that they will run only at certain times of the day, or
by specifying a minimum time that must elapse between builds
* Extension modules facility, allowing for performing tasks such as
building and testing non-core units like drivers, or runnign
extra non-standard tests, without having to touch the standard
buildfarm code. This is still experimental.
* bug fix for certain failure names in SCM module
* bug fixes for isolation checks
* bug fix for stack trace locations
* bug fix for objdump name when using --host config

Enjoy.

cheers
