244e2e1451 Write SSSE3 sub-pixel filter function
1. Process 16 pixels at one time instead of 8.
2. Add check for both xoffset =0 and yoffset=0, which happens
   during motion search.
This change gave encoder 1%~3% performance gain.

e6948bf0f9 Fix a multi-line format-string warning.
GCC 4.5 and 4.6 both issue a warning about the multi-line format
string introduced in bc9c30a0, which also changed the whitespace
in the associated stt file by line-wrapping the long format string.

Instead, use multiple string constants, which the compiler will
concatenate. This maintains the original formatting, but remains
legible within the standard line length.

5d1d9911cb correct zbin boost for splitmv mode
Disable zbin boost in SPLITMV mode as intended. Was incorrectly looking
at vp8_ref_frame_order instead of vp8_mode_order when comparing against
SPLITMV. This condition should have always been false, as SPLITMV is
not in the range of valid reference frames.

fe9a604b1e Fix format-string warning
Cast size_t to (unsigned long) and print it with the %lu format
string, which is more portable than C99's explict %zu for size_t.

This truncates on Windows x64 but otherwise works on 32 and 64 bit
platforms. In practice the stats file is unlikely to be so large.

bc9c30a003 Improved key frame detection.
In some cases where clips have been encoded with
borders (eg. some wide-screen content where there is a
border top and bottom and slide shows containing portrait
format photographs (border left and right)) key frames were
not being correctly detected.

The new code looks to measure cases where a portion of
the image can be coded equally easily using intra or inter
modes and where the resulting error score is also very low.
These "neutral" areas are then discounted in the key frame
detection code.

9fc8cb39aa Improved KF insertion after fades to still.
This code extends what was previously done for GFs, to pick
cases where insertion of a key frame after a fade (or other
transition or complex motion)  followed by a still section, will
be beneficial and will reduce the number of forced key frames.

36be4f7f06 Fix drastic undershoot in long form content
When the modified_error_left accumulator exceeds INT_MAX, an incorrect
cast to int resulted in a negative value, causing the rate control to
allocate no bits to that keyframe group, leading to severe undershoot
and subsequent poor quality.

This error was exposed by the recent change to the rolling target and
actual spend accumulators in commit 305be4e4 which fixed them to
actually calculate the average value rather than be re-initialized
on every frame to the average per-frame bitrate. When this bug was
triggered, the target bitrate could be 0, so the rolling target
becomes small, which causes the undershoot. The code prior to 305be4e4
did not exhibit this behavior because the rolling target was always
set to a reasonable value and was independent of the actual target
bitrate. With this patch, the actual target bitrate is calculated
correctly, and the rate control tracks as expected.

This cast was likely added to silence a compiler warning on a comparison
between a double (modified_error_left) and an int (0). Instead, this
patch removes the cast and changes the comparison to be against 0.0,
which should prevent the warning from reoccuring.

This fixes issue #289. Special thanks to gnafu for his efforts in
reporting and debugging this fix.

06ce0d8830 change CFLAGS for 64 bit icc builds
AMD64 only implies SSE2, not SSE3. There aren't any known cases where
icc was generating SSE3 instructions since all the vectorizable code
is already in handwritten asm, so this fix is included mostly for
correctness. Fixes issue #259.
