[PATCH V2 0/4] Add support for "legacy" linespecs

[Keith Seitz <keiths at redhat dot com>]

When I committed the locations API patchset, I ignored the need for
"legacy" support. Specifically, MI, python, and guile all require the
ability to convert an old-style linespec (which can be a linespec, address,
or probe location) into an event_location.

Python and guile code assumes everything is a linespec location, so neither
probe nor address locations are available to them.

MI uses string_to_event_location, but that allows CLI-style explicit
locations. MI already supports MI-style explicit locations.

This patchset is an attempt to address this by adding a new locations API
function, string_to_event_location_basic, which implements a generic
string-to-struct event_location routine which converts these (so-called)
"legacy" linespecs.

Keith Seitz (4):
      Refactor string_to_event_location for legacy linespec support.
      python/19506 -- gdb.Breakpoint address location regression
      Use string_to_event_location_basic in guile.
      Enable/update legacy linespecs in MI.
