6e7b50b427 mpegvideo_enc: drop support for reusing the input motion vectors. 
This misfeature is most likely completely useless and conflicts with
removing the mpegvideo-specific fields from AVFrame. In the improbable
case it is actually useful, it should be reimplemented in a better way.

25841dfe80 Use ptrdiff_t instead of int for {avg, put}_pixels line_size parameter. 
This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

a34a609fc1 motion_est: fix use of inline on extern functions 
Inline functions declared without extern do not provide an external
definition in standard C99.  This code only works because most
compilers do not implement the inline semantics correctly.  With a
stricter compiler, linking fails with unresolved references to these
functions.

Declaring the functions extern inline works correctly with some
compilers while some others still fail to create external definitions.

For maximum portability, create a static inline version with an
externally visible wrapper for ff_get_mb_score.  ff_epzs_motion_search
is so large that no sane compiler inlines it anyway, so there the
inline keyword can simply be dropped with no effect.

0db9eba48c motion_est: drop inline from sad_hpel_motion_search() 
This function is only ever called through a function pointer,

74f82f92a4 motion_est: remove useless no_motion_search() function 
At both places this function is called, mb_[xy] == s->mb_[xy]
making the call together with following code equivalent to
