not the worker signal handler.
There's no reason to call it from the signal handler -
it returns the CPU for the entire process, not the calling thread.
And it may be asynch-signal-handler-unsafe.
- API: comment out checks for bad CPU times.
I don't think this is needed now, and in some cases it's wrong
(multi-threaded apps can accumulate CPU faster than real time)
- API, Unix: in boinc_calling_thread_cpu_time(), don't retry getrusage().
- Bossa: switch to better class structure (suggested by Nicolas Alvarez).
Haven't switched to mysqli yet, but will later.
Also various other Bossa fixes
