[fpc-pascal] Logging full runtime-error/exception backtrace

[Everton Vieira]

I've tried sometimes to do directly with the -gl and the BackTraceStrFunc
and i never was able to get the info of the error, maybe my fault. With
this units that i've passed i was able to get the info of the error with
the line number and everything else within the app.
