for use by watchpoints.

breakpoints when the watchpoint goes out of scope. Save & restore

watchpoints. Delete the watchpoint and watchpoint scope breakpoint
when the watchpoint goes out of scope. Remove and reinsert all
breakpoints before returning if we stopped when a hardware watchpoint
fired.

watching a local expression, build a scope breakpoint too.
(map_breakpoint_numbers): Also call given function for any
related breakpoints.

breakpoints, but recompute the watchpoint_scope breakpoint's
frame and address (if we have an associated scope breakpoint).

watchpoints. When necessary handle watchpoint_scope breakpoints.

stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
symm-nat.c. Define CHILD_WAIT and declare child_wait().

tm-i386v.h is apparently OK.
* config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
HAVE_TERMIO. Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
USE_O_NOCTTY.

Change all printf formats from %x to %lx if outputting an address.
Change la_*_format to use long format.
local_hex_string, local_hex_string_custom now take an unsigned long
argument, change all callers.

complaint output.
* dbxread.c (end_psymtab): Cast MSYMBOL_INFO to long, not int.
* findvar.c, value.h (write_register): Change register value to long.
* gdbtypes.h (struct type): Change `bitsize' to long as
TYPE_FIELD_STATIC_PHYSNAME uses this field as a pointer.

CORE_ADDR.
* language.h (local_octal_string, local_octal_string_custom):
Remove prototype, the functions are neither defined nor used.

* solib.c (solib_map_sections): Use bfd_get_filename
to access filename field.
