[PATCH 0/7] Replace continuations with an extendable "class"

[Pedro Alves <palves@redhat.com>]

Mainly, this series replaces the continuations mechanism with a
"class" that manages a thread's execution-command-specific state.
This fixes bugs, and cleans up core run control and interpreter code
in the process, as well as clearing the path for further
fixes/cleanups.

Pedro Alves (7):
  Merge async and sync code paths some more
  Replace "struct continuation" mechanism by something more extensible
  Convert infcalls to thread_fsm mechanism
  Convert the until/advance commands to thread_fsm mechanism
  Garbage collect dummy_frame_ctx_saver
  Garbage collect thread continuations
  Delete enum inferior_event_handler::INF_TIMER
