structure members. Replace `suspend_count' counter by a
`suspended' flag.
* win32-low.c (thread_rec): Update condition of when to get the
context from the inferior. Rely on ContextFlags being set if it
has already been retrieved. Only suspend the inferior thread if
we haven't already. Warn if that fails.
(continue_one_thread): s/suspend_count/suspended/. Only call
ResumeThread once. Warn if that fails.
debug_registers_used, CONTEXT_EXTENDED_REGISTERS,
CONTEXT_FLOATING_POINT, CONTEXT_DEBUG_REGISTERS,
CONTEXT_DEBUGGER, CONTEXT_DEBUGGER_DR): Delete.
(thread_rec): Get context using the low target.
(child_add_thread): Call thread_added on the low target,
which does the same thing.
(regptr): Delete.
(do_initial_child_stuff): Remove debug registers references.
Set context using the low target. Resume threads after
setting the contexts.
(child_continue): Remove dead variable. Remove debug
registers references.
(child_fetch_inferior_registers): Go through the low target.
(do_child_store_inferior_registers): Remove.
(child_store_inferior_registers): Go through the low target.
(win32_resume): Remove debug registers references.
Set context using the low target.
(handle_exception): Change return type to void. Don't record
context here. Set status to TARGET_WAITKIND_SPURIOUS on a
first chance exception.
(get_child_debug_event): Change return type to void. Remove
goto loop. Always return after waiting for debug event.
(win32_wait): Convert to switch statement. Handle spurious
events.
* win32-i386-low.c (debug_registers_changed,
debug_registers_used): New.
(initial_stuff): Rename to ...
(i386_initial_stuff): ... this. Clear debug registers
state variables.
(store_debug_registers): Delete.

(load_debug_registers): Delete.
(i386_set_thread_context): New.
(i386_thread_added): New.

(do_fetch_inferior_registers): Rename to ...
(i386_fetch_inferior_register): ... this.
(i386_store_inferior_register): New.
(the_low_target): Adapt to new interface.
* win32-arm-low.c (CONTEXT_FLOATING_POINT): Define.
(arm_get_thread_context): New.
(arm_set_thread_context): New.
(regptr): New.
(do_fetch_inferior_registers): Rename to ...
(arm_fetch_inferior_register): ... this.
(arm_store_inferior_register): New.
(arm_wince_breakpoint): Reimplement as unsigned long.
(arm_wince_breakpoint_len): Define.
(the_low_target): Adapt to new interface.
* win32-low.h (target_ops): Remove regmap, store_debug_registers and
load_debug_registers. Add get_thread_context, set_thread_context,
thread_added and store_inferior_register. Rename
fetch_inferior_registers to fetch_inferior_register.
(regptr): Remove declaration.
