[PATCH 0/5] Implement Ada Pragma Import and Pragma Export

[Tom Tromey <tromey@adacore.com>]

This adds better support to GDB for Ada's import and export feature.
There are some minor cleanups to start with, then the bulk of the
feature in the last patch, which I think should be reasonably
self-explanatory.

Regression tested on x86-64 Fedora 36.  It's also been running in the
AdaCore internal test suite for a while.
