ac090fa68c lavu: keep context size variables
They are essential to be able to use the utils without av_malloc()
That is for example use with malloc(), memalign(), some other
private allocation function, on the stack or others.

9a92aea27b avutil: Add functions for allocating opaque contexts for algorithms
The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.

If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).

045b60bf9b Make SHA digest function write digest value with AV_WN32 instead of assuming
that output may be written as uint32_t since output buffer may not be aligned
(and it's silly to force alignment on it) and it does not work in that case
properly on some architectures.
