Implement just in time debug feature for runonphone

When the test being run crashes, runonphone will now retrieve the
registers and call stack for the crashing thread from the phone and save
to a crash log (compatible with d_exc crash logs, so existing tools can
be used to analyse the log)

To disable just in time debug, use --nocrashlog on the command line
To save the crash logs to a different location, use --crashlogpath <path>
   otherwise, they are saved to the working directory.

To convert the crash logs into human readable form, use the crash
analyser carbide plugin from symbian foundation; or another symbian tool
that can process d_exc style logs.
