[PATCH 0/5] New Python hook for missing debug information

[Andrew Burgess <aburgess@redhat.com>]

This series adds a new Python hook to GDB, this hook allows a user to
register a handler object which will be called whenever GDB fails to
locate any debug information for an objfile it is loading.  These
handler objects can (potentially) perform host or project specific
actions to help GDB locate the missing debug information.

Commits #1 and #2 are refactoring.  These merge the separate debug
information lookup code from coffread.c and elfread.c.

Commit #3 is more refactoring, this simplifies the now merged code.

Commit #4 implements the framework for the new hook within GDB, but
doesn't implement the Python side of things yet.

Commit #5 is where I add the Python side of things, it's only at this
point that a user can actually hook into GDB.
