Straightforward fatal to internal_error conversions

This commit replaces most of the calls to fatal that represent
internal errors with calls to internal_error, either directly
or via gdb_assert and gdb_assert_not_reached.

gdb/gdbserver/ChangeLog:

	* inferiors.c (get_thread_process): Replace check with gdb_assert.
	* linux-low.c (linux_wait_for_event_filtered): Replace fatal with
	internal_error.
	(linux_resume_one_lwp): Likewise.
	* linux-x86-low.c (x86_siginfo_fixup): Replace checks with
	gdb_assert.
	* mem-break.c (raw_bkpt_type_to_target_hw_bp_type): Replace fatal
	with internal_error.
	* regcache.c (get_thread_regcache): Replace check with gdb_assert.
	(init_register_cache): Replace fatal with gdb_assert_not_reached.
	(find_register_by_name): Replace fatal with internal_error.
