Test code.
fella.c avoids strict aliasing with compiler optimizations.
Set plaintext value in verify().
Merge branch 'master' into strict_aliasing
Changed type of `Block`.
Working .
New test.
Updated display_context().
Merge branch 'master' into strict_aliasing

Conflicts:
	authenc/aez.c
Pass pointers to blocks when writing to them.

For some reason I thought `Block` would behave like an
array ... boy was I wrong :/
Updated cp_block() and zero_block().
Better ahash().
xor_block() and xor_bytes().

I wnat to benchmark this, then see if I can improve speed
by removing more xor_bytes().
Stack smashing bug in ahash().

Only noticed it with optimized compiler.
Faster benchmarking.
