[Tarantool-patches] [PATCH v6 2/2] base64: improve decoder performance

[Alexander Turenko]

So we have four topics:

1. Why don't remove the unused (status storing) code?
2. Internal API changes that we definitely should do: error reporting
   for too short output buffer.
3. Internal API changes that are subject to discussion: input
   validation.
4. Optimizations.

I highly want to define precisely the internal API first (have agreement
on 1, 2, 3 at least, but better have it implemented) and only then
discuss optimizations. Otherwise any proposed optimization may become
impossible (or just unneeded).

Sorry, but I'll postpone the discussion regarding optimizations because
of this.

WBR, Alexander Turenko.
