Refactor timeout scaling factor initialization In order to stabilize tests on (heavily loaded) CI infrastructure, reasses scaling factor every three minutes. Also include (simple) I/O benchmark to compensate for (overloaded) I/O subsystem of CI slaves. For details, see `Builder::TestReport::Result >> timeoutScale`

Support for deployable-package building.

Over time, move stuff which helps to generate makefiles, packages, nullsoft installers
etc. to here.
Also, scripts to run testsuites and convert to hudson/jenkins readable formats are found
in subdirectories here.
