Add a new control of golden frame boost in CBR mode

Browse Source 
0 means that golden boost is off, and uses average frame target rate,
a non-zero number means the percentage of boost over average frame
bitrate is given initially to golden frames in CBR mode.

*
* This value controls the amount of boost given to Golden Frame in
* CBR mode. It is expressed as a percentage of the average
* per-frame bitrate, with the special (and default) value 0 meaning
* the feature is off, i.e., no golden frame boost in CBR mode and
* average bitrate target is used.
*
* For example, to allow 100% more bits, i.e, 2X, in a golden frame
