The code represents a considerable maintenance burden and it is not
clear that it gives a noticeable benefit to outweigh this after 10
years of improvements in compiler technology since its creation.
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.

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).

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

depending on CONFIG_SMALL this can either be compiled to a fully unrolled kernel / rfc reference style md5 routine
or a single loop similar to what mplayer uses
