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.
