Initial-checkin for ON2 Software AVC/H264 decoder

o when neon is present, the performance gain of On2 AVC software decoder
  over PV software decoder is more than 30%.

o In addition, it fixes some known PV software decoder issues like missing
  output frames

o allow both pv and on2 software avc to be available for easy comparision

o change output frames from 8 to 16

+ * Function:  omxVCM4P2_MEGetBufSize   (6.2.4.1.1)
+ *
+ * Description:
+ * Computes the size, in bytes, of the vendor-specific specification 
+ * structure for the following motion estimation functions: 
+ * BlockMatch_Integer_8x8, BlockMatch_Integer_16x16, and MotionEstimationMB. 
+ *
+ * Input Arguments:
+ *   
+ *   MEmode - motion estimation mode; available modes are defined by the 
+ *            enumerated type OMXVCM4P2MEMode 
+ *   pMEParams - motion estimation parameters 
+ *
+ * Output Arguments:
+ *   
+ *   pSize - pointer to the number of bytes required for the specification 
+ *            structure 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - one or more of the following is true: 
+ *    -    an invalid value was specified for the parameter MEmode 
+ *    -    a negative or zero value was specified for the 
+ *         parameter pMEParams->searchRange
