[PATCHv2 0/3] gdb: allow 'until' to work in outermost frame

[Andrew Burgess <aburgess@redhat.com>]

Series has expanded since V1!

The previous iteration used program_space::entry_point_address_query
to figure out which frame was the enty frame.  But this frame is the
entry frame within the main executable, not the actual entry frame for
the whole inferior, i.e the entry frame for the run-time linker in a
dynamically linked executable.  That's why the test in the previous
version needed to be compiled with the '-static' flag.

I figured that this was just another bug in GDB, and started looking
at how to fix this so that program_space::entry_point_address_query
would return the actual entry address for the whole inferior.

But I figure that for things like displaced stepping using the entry
address of the executable probably makes the more sense, so then I
started looking at ways we could make use of both possible entry
address values.  And that's what this series does.

Patch #1 renames some functions ready for the later patches.

Patch #2 adds a mechanism to access both entry address values.

Patch #3 fixes 'until' using infrastructure from the previous patch.

Thanks,
Andrew
