[non-stop] 05/10 Refactor a bit infrun.c

[Pedro Alves]

What's context switched, and what's just used while handling an
event is seriously spread all over currently.  This patch
is a stepping in cleaning that up a bit, by splitting
execution_control_state in three:

/* Context-switchable data.  */
struct thread_stepping_state
{
  /* Should we step over breakpoint next time keep_going
     is called?  */
  int stepping_over_breakpoint;
  struct symtab_and_line sal;
  int current_line;
  struct symtab *current_symtab;
  int step_after_step_resume_breakpoint;
  int stepping_through_solib_after_catch;
  bpstat stepping_through_solib_catchpoints;
};

/* Data to be passed around while handling an event.  This data is
   discarded between events.  */
struct execution_control_state
{
  ptid_t ptid;
  struct target_waitstatus ws;
  int random_signal;
  CORE_ADDR stop_func_start;
  CORE_ADDR stop_func_end;
  char *stop_func_name;
  int new_thread_event;
  int wait_some_more;
};

/* global inferior control state P/

/* The PTID we'll do a target_wait on.*/
ptid_t waiton_ptid;

/* Current inferior wait state.  */
enum infwait_states infwait_state;
