Don't misencode C-generated messages

Also, be more consistent about calls to 'Fmessage' vs 'message'.
* src/alloc.c (Fgc_status):
Prefer AUTO_STRING to build_string for Fmessage call.
* src/data.c (Fmake_variable_buffer_local)
(Fmake_local_variable, Fmake_variable_frame_local):
* src/doc.c (store_function_docstring):
Use Fmessage, not message, since the argument can contain
non-ASCII characters, and this can cause the resulting message
to be incorrectly encoded for the current environment.
* src/fns.c (maybe_resize_hash_table):
* src/xselect.c (x_clipboard_manager_save_all):
Use message, not Fmessage, since Fmessage's power isn't needed here.
* src/process.c (Fmake_network_process): Reword message to avoid %s.
* src/xdisp.c (vmessage): Document restrictions on message contents.
(message_nolog) [false]: Remove unused code.
