GDB MetaModelica type inspection

[adeas31]

Short

MetaModelica data types are stored as C void pointers. They need to be cast/interpreted to make the raw data visible.
Basically call printAny from OMCompiler.

Target

• Manually run OpenModelica Compiler with GDB, stop at a breakpoint and inspect the program variables.
• For e.g. an array of records display what type the data has and what values, all the way down to the basic types (number, string, boolean)

Tasks

• Convert C void pointer to MetaModelica data types.
• Add unit test to: start gdb, run omc on some minimal example, stop at breakpoint, inspect variables.
