Message:

Merge changes to benchmarking tool (PR #151)

This merges refactoring and other changes to the perf/hbench tool.

The changes include:

• Factor out all the duplicate code in individual benchmarks into a common harness
• Properly compute average throughput
  • Added an awful function to compute square root until proper implementation is available (for the precision we need it is quite sufficient) [sqrt is needed to compute standard deviation]
• Added option to dump data to CSV for further processing
• Added option to specify minimal duration of a loop and number of runs to execute.
• Added simple benchmark for fibril mutexes
• Merged benchmarks from bnchmark application and removed it
  • These benchmarks are FS-related and IMHO are quite badly designed (they really stress only the block cache and not the FS on top of it; but still they might be useful as IPC benchmark of large data volumes)
• Renamed perf to hbench to stress that it is a benchmarking application rather than a generic performance measurement tool (compared to perf in GNU/Linux)
• Extended documentation a little bit
• Added function for measuring wall-clock time (internally pass-through to uptime but available for other applications as the right API for this in HelenOS)
