[965] Allow more than one draw_prims per batchbuffer.

The comment about (vbo)_exec_api.c appeared to be stale, as the VBO code seems
to only use non-named VBOs (not actual VBOs) or freshly-allocated VBO data.

This brings a 2x speedup to openarena, because we can submit nearly-full
batchbuffers instead of many 450-byte ones.
