Dmitry Frank 23122b327c Remove old docs, rename docs_new to docs
It would be probably good idea to also remove tools/docgen.py and
asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which
may contain some useful info which we'll need at least to review before
removing.

int mg_base64_decode(const unsigned char *s, int len, char *dst);
---
Decode base64-encoded string `s`, `len` into the destination `dst`.
Destination has to have enough space to hold decoded buffer.
Decoding stops either when all string has been decoded, or invalid
character appeared.
Destination is '\0'-terminated.
Return number of decoded characters. On success, that should be equal to
`len`. On error (invalid character) the return value is smaller then `len`.
