C Debugging Support

[adriweb]

In the old wishlist, there was an item "Look at this gdb-z80 project (code from 2011...) ; try to see if it can be updated for eZ80, and used with a CEmu GDB stub. Mainlining such code is highly preferable.".

However, with @drdnar's linker (see ezCalcLink) and any related things that can come out of it, debugging support would already be much better, at least regarding C things (debug symbols, any additional info in the binary, etc.), so the need of an actual GDB stub might not be so important anymore (considering the amount of work required on GDB itself).

This issue is thus for the eventual ezCalcLink "integration": what exactly, how, etc.

Note: this may now also be related to lldb and other tools from LLVM.

Since linking will be taken care of in fasmg most likely, output symbols should already be better in theory.
