Added a new property "compliance-mode", which default is the normal strict compliant mode. The second mode, "restrict-buf-alloc", is to limit the coded buffer allocation size to improve performance in some specific Intel platforms (there is asignificant performance improvement in parallel encodings). Under this new mode, we use the MinCR field in A.3.1 for pre-calculating the coded-buffer size. https://bugzilla.gnome.org/show_bug.cgi?id=784590
