BIPRED ME was discarding the halfpel motion vector components
in cost computation. That is fixed now.

The stored i4_mb_distortion that was used as i4_max_sad previously
might come from a different coding mode - even if
pf_ime_compute_sad_16x16 returns early when i4_mb_distortion is
larger than ps_mb_ctxt_bi->i4_mb_distortion, the calculated i4_mb_cost
can still end up smaller than ps_mb_ctxt_bi->i4_mb_cost.
Therefore, set i4_max_sad to INT_MAX to avoid the early exit in
pf_ime_compute_sad_16x16 here, since it can't be used reliably (and
returning early can end up choosing a suboptimal mode).
This makes sure that the encoded output is identical when the SIMD
optimized routines are disabled, when using B-frames.

This fixes building with compilers that are strict about the pre-C99
rule about having all variable declarations before statements.
(The previous version of this commit was originally made before
the commit adding support for main profile, which added a bunch
more similar issues.)

If the data is read directly from the input buffer, set the stride
values to those of the input buffer. If the data is copied, set the
stride to the value of the local buffer instead.
This fixes handling of cases where the input buffer stride is
(significantly) larger than the maxwidth of the video.
This also effectively makes the parameter
ive_ctl_set_dimensions_ip_t.u4_strd useless - nothing needs to
know the stride until you actually encode a frame, and at that point,
we can either use the stride of the input buffer, or of the local
pu1_y_csc_buf_base where the copied content is stored.
