gdbserver: turn target ops 'multifs_{open, readlink, unlink}' into methods
gdbserver/ChangeLog:
2020-02-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
Turn process_stratum_target's multifs_open, multifs_readlink,
multifs_unlink ops into methods of process_target.
* target.h (struct process_stratum_target): Remove the target ops.
(class process_target): Add the target ops. Also add
'supports_multifs'.
* target.cc: Include "fcntl.h", "unistd.h", "sys/types.h", and
"sys/stat.h".
(process_target::supports_multifs): Define.
(process_target::multifs_open): Define.
(process_target::multifs_readlink): Define.
(process_target::multifs_unlink): Define.
Update the derived classes and callers below.
* hostio.cc (handle_setfs): Update.
(handle_open): Update.
(handle_unlink): Update.
(handle_readlink): Update.
* linux-low.cc (linux_target_ops): Update.
(linux_process_target::supports_multifs): Define.
(linux_process_target::multifs_open): Define.
(linux_process_target::multifs_readlink): Define.
(linux_process_target::multifs_unlink): Define.
* linux-low.h (class linux_process_target): Update.
* lynx-low.cc (lynx_target_ops): Update.
* nto-low.cc (nto_target_ops): Update.
* win32-low.cc (win32_target_ops): Update.
