[PATCH 00/25] Many updates to DAP implementation

[Tom Tromey]

I've been working steadily on the DAP implementation.  This series
combines a number of patches.

It starts with some general refactoring of Ada catchpoints, to make
them work more like C++ catchpoints.  In particular, now they can be
set before the inferior has started.  This is then used to implement
the DAP setExceptionBreakpoints request.

Other patches add DAP features.  In some cases a new Python API is
added so that it can be used by DAP.

I do have some more patches to come after this series goes in.

Regression tested on x86-64 Fedora 36.
