This is the same patch, refreshed to apply on top of Jan's bp_location
renaming patch. It also incorporates some additional renaming he did
that touched this patch. I understand that this patch is approved. I'll
commit it when the ranged and/or the masked watchpoints patch get in.

Convert hardware watchpoints to use breakpoint_ops.
gdb/
* breakpoint.h (breakpoint_ops) <insert>: Rename to...
<insert_location>: ... this. Return int instead of void.
Accept pointer to struct bp_location instead of pointer to
struct breakpoint. Adapt all implementations.
(breakpoint_ops) <remove>: Rename to...
<remove_location>: ... this. Accept pointer to struct bp_location
instead of pointer to struct breakpoint. Adapt all implementations.
* breakpoint.c (insert_catchpoint): Delete function.
(insert_bp_location): Call the watchpoint or catchpoint's
breakpoint_ops.insert method.
(remove_breakpoint_1): Call the watchpoint or catchpoint's
breakpoint_ops.remove method.
(insert_watchpoint, remove_watchpoint): New functions.
(watchpoint_breakpoint_ops): New structure.
(watch_command_1): Initialize the OPS field.
* inf-child.c (inf_child_insert_fork_catchpoint)
(inf_child_remove_fork_catchpoint, inf_child_insert_vfork_catchpoint)
(inf_child_remove_vfork_catchpoint, inf_child_insert_exec_catchpoint)
(inf_child_remove_exec_catchpoint, inf_child_set_syscall_catchpoint):
Delete functions.
(inf_child_target): Remove initialization of to_insert_fork_catchpoint,
to_remove_fork_catchpoint, to_insert_vfork_catchpoint,
to_remove_vfork_catchpoint, to_insert_exec_catchpoint,
to_remove_exec_catchpoint and to_set_syscall_catchpoint.
* target.c (update_current_target): Change default implementation of
to_insert_fork_catchpoint, to_remove_fork_catchpoint,
to_insert_vfork_catchpoint, to_remove_vfork_catchpoint,
to_insert_exec_catchpoint, to_remove_exec_catchpoint and
to_set_syscall_catchpoint to return_one.
(debug_to_insert_fork_catchpoint, debug_to_insert_vfork_catchpoint)
(debug_to_insert_exec_catchpoint): Report return value.
* target.h (to_insert_fork_catchpoint, to_insert_vfork_catchpoint)
(to_insert_exec_catchpoint): Change declaration to return int instead
of void.
gdb/testsuite/
* gdb.base/foll-exec.exp: Adapt to new error string when the catchpoint
type is not supported.
* gdb.base/foll-fork.exp: Likewise.
* gdb.base/foll-vfork.exp: Likewise.
