Add support for job pools

Commands can now be assigned to an arbitrary job pool and a limit for
the number of concurrently running jobs in such pools can be provided in
a number of ways:
- via the build command line: qbs --job-limits linker:1
- via the settings: qbs config preferences.jobLimit.linker 1
- in a project file: JobLimit {
                         jobPool: "linker";
                         jobCount: 1
                     }
We provide two job pools ourselves with the cpp module: "compiler" and
"linker".

[ChangeLog] Added the concept of job pools for limiting concurrent
execution of commands by type
