[Tankut Baris Aktemur <tankut dot baris dot aktemur at intel dot com>]

gdbserver/ChangeLog:
2020-02-10  Tankut Baris Aktemur  <tankut.baris.aktemur@intel.com>

	Make process_stratum_target's get_ipa_tdesc_idx op a method of
	process_target.

	* target.h (struct process_stratum_target): Remove the target op.
	(class process_target): Add the target op.
	(target_get_ipa_tdesc_idx): Update the macro.
	* target.c (process_target::get_ipa_tdesc_idx): Define.

	Update the derived structs and callers below.

	* linux-low.c (linux_target_ops): Update.
	(linux_get_ipa_tdesc_idx): Turn into ...
	(linux_process_target::get_ipa_tdesc_idx): ... this.
	* linux-low.h (class linux_process_target): Update.
	* lynx-low.c (lynx_target_ops): Update.
	* nto-low.c (nto_target_ops): Update.
	* win32-low.c (win32_target_ops): Update.
