This commit adds #ifdef __cpluscplus guard in odintrin.h to enable
the build of related test in C++.

Replaces an approximate unsigned integer division with the bit exact
OD_ILOG() implementation.
Removes the need to call vp10_temporal_filter_init() before calling
vp10_temporal_filter_apply_c() by using a static table of constants.

This ports the OD_DIVU_SMALL code from Daala to AOM so that divides by
constants smaller than OD_DIVU_DMAX (1024) are done using a multiply.
Added a unit test for OD_DIVU_SMALL in test/divu_small_test.cc.

Instead of dividing the squared partial sums by the number n of pixels in the
line, we multiply by 840/n, where 840=3*5*7*8. This not only avoids the
divisions, but it also makes the optimization exact as there is no more
rounding.

This fixes VP10/ActiveMapRefreshTest.Test/*.
Bring commits 575e81f and 3d6b8a6 to aom/vp10. These changes predate
the creation of the active map cyclic refresh test.

The Daala implementation of OD_ILOG(x) computes the number of bits
necessary to represent the unsigned integer x in two's compliment.
We adjust the computation in od_dering.c to better approximate the
log base 2 and match the previous OD_ILOG() definition.
This commit makes no change to the bitstream.
