DAP_INFO_CAPABILITIES should be available

[UweBonnes]

Hello,

I am trying to get the Blackmagic Debugger running with CMSIS_Dap adapters. I found your edbg a good start. As the DAP_PORT_JTAG may bot be implemented, is is needed outside of dap.c to know of "J" is in the return of ID_DAP_INFO/DAP_INFO_CAPABILITIES.

What would you propose to export these values?

Yes, I think the fix for zero-length strings issue will do that automatically. I plan to add the ability to request any information and do the debugger info formatting from edbg.c. This will expose all those things.

This is addressed in the most recent commit. There is now a dap_info() call that will return necessary information and capabilities definitions are also moved into the header file.
