[PATCH 0/9] Implement the DAP "loadedSources" request

[Tom Tromey <tromey@adacore.com>]

This series implements the DAP "loadedSources" request.  However, it
does so by exposing MI commands to Python, with MI output being
converted to Python objects via a new ui_out implementation.

Regression tested on x86-64 Fedora 36.
