gdbserver: turn target ops 'insert_point' and 'remove_point' into methods
gdbserver/ChangeLog:
2020-02-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
Turn process_stratum_target's insert_point and remove_point ops
into methods of process_target.
* target.h (struct process_stratum_target): Remove the target ops.
(class process_target): Add the target ops.
* target.cc (process_target::insert_point): Define.
(process_target::remove_point): Define.
Update the derived classes and callers below.
* mem-break.cc (set_raw_breakpoint_at): Update.
(delete_raw_breakpoint): Update.
(uninsert_raw_breakpoint): Update.
(reinsert_raw_breakpoint): Update.
* linux-low.cc (linux_target_ops): Update.
(linux_insert_point): Turn into ...
(linux_process_target::insert_point): ... this.
(linux_remove_point): Turn into ...
(linux_process_target::remove_point): ... this.
* linux-low.h (class linux_process_target): Update.
* lynx-low.cc (lynx_target_ops): Update.
* nto-low.cc (nto_target_ops): Update.
(nto_insert_point): Turn into ...
(nto_process_target::insert_point): ... this.
(nto_remove_point): Turn into ...
(nto_process_target::remove_point): ... this.
* nto-low.h (class nto_process_target): Update.
* win32-low.cc (win32_target_ops): Update.
(win32_insert_point): Turn into ...
(win32_process_target::insert_point): ... this.
(win32_remove_point): Turn into ...
(win32_process_target::remove_point): ... this.
* win32-low.h (class win32_process_target): Update.
