Protect new metric computation with use_highbitdepth flag
The computation of new metrics is not supported yet in highbitdepth

Skip the last frame update for some frame repeats.
Where a frame appears to be a repeat of an earlier
frame or frame buffer, but the first pass code
does not anticipate this (usually because it is matching
the GF or ARF buffer not the last frame buffer), do not
update the last frame buffer.
This helps ensure that the content of the last frame buffer
is kept "different" where possible, and not updated to
match the GF or ARF. This is particularly helpful in some
animated sequences where there are groups of repeating
frames. Here it has quite a big impact. However, in most
of our standard test clips it has little or no impact.

replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNED
this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

Remove CONSTRAIN_NEIGHBORING_MIN_MAX.
Remove one of the auto partition size cases.
This case can behaves badly in some types of animated content

Previously limit on max interval set to 0.5 seconds.
Though this helped some low frame rate material it
appears to be a bit too aggressive for some 24 and 25 fps
content. This patch relaxes the limit to 0.75 seconds.
The patch also adds a new minimum interval variable
to replace the current hard wired value. This allows us
to impose a limit on the maximum number of primary
arfs per second for high frame rate (e.g. 50 & 60fps)
content. This is to address concerns regarding playback
performance on some platforms if there is a high base
frame rate and very frequent arfs.
