Migration of buildbot heavy slaves

[mloskot]

Buildbot has been upgraded (#491) and now it's ready to move slaves, particularly heavy slaves, off buildbot.osgeo.org to buildtest.osgeo.

[mloskot]

* Created buildbot group and user on buildtest machine:

$ groupadd buildbot
$ useradd -d /osgeo/buildbot -g buildbot -s /bin/bash buildbot

It seems it's safe to ignore the syntax error message thrown during installation.

I nearly finished the migration. I'll continue on Sunday to complete.

In the meantime, please do not start buildbot, neither masters nor slaves, on xblade14-2 machine.

[mloskot]

Installed GEOS 3.2.0 and PROJ.4 4.7.0 on buildtest machine.

[mloskot]

The migration has been finished and GDAL has moved to buildtest.osgeo.org.

By the way, I've reorganised management scripts and configuration, so it's more flexible to maintain distributed instances. The buildbot module in SVN consits of both configuration sets, for xblade14-2 and xblade11-2, separated.

Second change is that previously, slaves and masters were organised by project, but now they are combined together by type of instance

masters/gdal
masters/geos
...

and

slaves/gdal
slaves/geos
...

This way it's easier to setup and maintain groups slaves distributed to different xblade machines, without messing masters sitting on one machine only.

I also merged the number of buildbot management scripts in to one buildbot_osgeo_ctl.sh script that controls all aspects of running buildbot instances.

I will update the Wiki  article to reflect all the changes I made.

In case of problems, let me know.
