[PATCH 0/3] Add some linker namespaces conveniences

[Guinevere Larsen <guinevere@redhat.com>]

This series is a second step in improving the User Experience of
debugging inferiors with multiple namespaces. It adds 2 things to make
it more convenient for users to understand what the inferior is doing.

The first patch adds convenience variables, specifically _active_namespaces
and _current_namespaces. These can be used to track where in the execution
of an inferior the user is, and could be used in breakpoint conditions
to stop at a specific namespace.

The third patch adds a new command, "info namespaces", to help the user
check what solibs are loaded, and where. To make the patch more
readable, the second patch is a minor refactor of the command "info
sharedlibrary".

Guinevere Larsen (3):
  gdb: add convenience variables around linker namespace debugging
  gdb: factor out printing a table of solibs for info sharedlibrary
  GDB: Introduce "info namespaces" command
