mpeg4 encoder does not have any of the profile/level standard

Summary of the request:
When encoding mpeg4 video (-c:v mpeg4) with ffmpeg, it does not have any limits of the various profile/levels for mpeg4 as found in MPEG-4 Part 2 and listed on this page
(see MPEG-4 Levels section)
So for instance, the max bitrate and max buffer size are not programmed, and the generated video can violate these limits. They have to be set manually (with -maxrate, -bufsize). Moreover, to get "Advanced Simple Profile", need to use '-profile 15', which is an odd number unfound in the documentation and has to be looked up in the source code.
How to reproduce:
% ffmpeg -i input -c:v mpeg4 ... output ffmpeg version N-55721-gc443689 built on Aug 22 2013 19:06:24 with gcc 4.7.3 (GCC)
Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.
