MECmpContext has several arrays of function pointers that are not set by ff_me_cmp_init(), but that are set by users to one of the other arrays via ff_set_cmp(). One of these other users is the motion estimation API. It uses MECmpContext.(me_pre|me|me_sub|mb)_cmp. It is basically the only user of these arrays. This commit therefore moves these arrays to MotionEstContext; this has the additional advantage of making motion_est.c more independent from MpegEncContext.
