g_output_stream_write_bytes() forces callers to deal with the possibility of partial writes, which is extremely inconvenient given that GBytes is immutable.

When writing a GBytes to an output stream, I would assume the caller almost always wants the entire buffer written to the stream, stopping only on error.  Similar to g_output_stream_write_all().

Ryan tells me changing g_output_stream_write_bytes() to behave this way would break compatibility, therefore I'd like to ask for a new set of functions which behave the way I initially thought g_output_stream_write_bytes() behaved:

   g_output_stream_write_all_bytes()
   g_object_stream_write_all_bytes_async()
   g_output_stream_write-all_bytes_finish()
