"libyuv/basic_types.h" includes <stddef.h>. So it is not necessary to
include both <stddef.h> and "libyuv/basic_types.h".

Audit all occurrences of "stride *" in the libyuv source tree. Ensure
that these multiplications are performed in the ptrdiff_t type.
For functions not declared in a public header (such as static
functions), prefer to declare the stride parameters (typically named
src_stride and dst_stride) and related stride local variables as
ptrdiff_t. If this is not possible, add ptrdiff_t casts to the stride
parameters in multiplications. If intptr_t or int64_t casts were used,
change them to ptrdiff_t casts.

The existing Neon code only makes use of 64-bit vectors throughout which
limits the performance on larger cores. To avoid this, swap the Neon
code from a Wx8 implementation to a Wx16 implementation and process
blocks of 16 full vectors at a time.
The original code also handled widths that were not exact multiples of
16, however this should already be handled by the "any" kernel so it is
removed.
Finally, avoid duplicating the TransposeWx16_C fallback kernel
definition in all architectures that need it, and just put it once in
rotate_common.cc instead.
Observed speedups for TransposePlane across a range of
micro-architectures:
Cortex-A53: -40.0%
Cortex-A55: -20.7%
Cortex-A57: -43.9%
Cortex-A510: -43.5%
Cortex-A520: -43.9%
Cortex-A720: -31.1%
Cortex-X2: -38.3%
Cortex-X4: -43.6%
