I386_USE_GENERIC_WATCHPOINTS and TARGET_HAS_HARDWARE_WATCHPOINTS.
(Native Debugging): Document I386_USE_GENERIC_WATCHPOINTS.

Unified support for hardware breakpoints and watchpoints on
x86 targets:

* config/i386/nm-i386.h: New file.

* config/i386/nm-i386.h: (i386_cleanup_dregs)
(i386_insert_watchpoint, i386_remove_watchpoint)
(i386_region_ok_for_watchpoint, i386_stopped_by_hwbp)
(i386_stopped_data_address, i386_insert_hw_breakpoint)
(i386_remove_hw_breakpoint): Declare prototypes.
[I386_USE_GENERIC_WATCHPOINTS] (TARGET_CAN_USE_HARDWARE_WATCHPOINT):
Define if not already defined.
(TARGET_REGION_OK_FOR_HW_WATCHPOINT, HAVE_CONTINUABLE_WATCHPOINT)
(STOPPED_BY_WATCHPOINT, target_stopped_data_address)
(target_insert_watchpoint, target_remove_watchpoint)
(target_insert_hw_breakpoint, target_remove_hw_breakpoint): Define
to call the appropriate i386_* functions.

* i386-nat.c: New file.

* i386-nat.c (I386_DR_CONTROL_MASK, I386_DR_LOCAL_ENABLE)
(I386_DR_GLOBAL_ENABLE, I386_DR_DISABLE, I386_DR_SET_RW_LEN)
(I386_DR_GET_RW_LEN, I386_DR_WATCH_HIT): New macros.
(dr_mirror, dr_status_mirror, dr_control_mirror, dr_ref_count)
(maint_show_dr): New variables.
(i386_cleanup_dregs, i386_show_dr, i386_length_and_rw_bits)
(i386_insert_aligned_watchpoint, i386_remove_aligned_watchpoint)
(i386_handle_nonaligned_watchpoint, i386_insert_watchpoint)
(i386_remove_watchpoint, i386_region_ok_for_watchpoint)
(i386_stopped_data_address, i386_stopped_by_hwbp)
(i386_insert_hw_breakpoint, i386_remove_hw_breakpoint): New
functions.
(_initialize_i386_nat): New function.
[I386_USE_GENERIC_WATCHPOINTS]: Add new maint command
`show-debug-regs', sets maint_show_dr to non-zero value and
activates debugging print-outs in functions which insert, remove,
and test watchpoints and hardware breakpoints.

* Makefile.in (i386-nat.o): New target.
(ALLDEPFILES): Add i386-nat.o.

* i386-tdep.c: Add back _initialize_i386_tdep prototype with
appropriate comment.

Prevent NULL pointer dereference.

Update Linux/Alpha port to use new Linux threads support.
