[TRAFODION-2433] Capture and log call trace upon internal assert failure.
This is an attempt to capture and log the function call trace incase of internal assertion call failures.
Initial change takes care capturing and logging for executor and some scenarios in compiler. There are additional scenarios in compiler(like in unregistered call back case) this capture can be extended, but currently not included. Additional scenarios can be extended in future.
For call trace functionality to work, linux system calls such as backtrace and backtrace_symbols is used. These calls require gcc compiler option "-rdynamic" be enabled. This compiler option does not generate debug symbols. More info on this is clearly articulated here for reference;

Sample output of assert failure call trace in logs as below.
