Also say `iv` const even if not required for the api update, just because it is
the case.

crypto/ccm: fix auth_data_len upperbound value
...
RFC3610 states that len_encoding is only valid for "0x0001 ... 0xFEFF"
If 0 < l(a) < (2^16 - 2^8), then the length field is encoded as two
octets which contain the value l(a) in most-significant-byte first
order.

Adds a cryptographically secure wipe function to wipe structs with
sensitive data. Works by first casting the pointer to a `volatile`
pointer to ensure that the compiler doesn't optimize the "memset" away.

Maximum input_len depends only on length_encoding and not auth_data_len.

3. The message m, consisting of a string of l(m) octets where 0 <=
l(m) < 2^(8L). The length restriction ensures that l(m) can be
encoded in a field of L octets.

sys: add ChaCha stream cipher and PRNG
...
This implementation is optimized for a little code and data size, not
for speed. IMO the code is more readable than in the reference
implementation.
The biggest advantage of ChaCha over other stream ciphers is the very
little data usage with only 64 bytes of context, and its good encryption
speed.
Also part of this PR is pseudo-random number generator, that just
returns the keystream of a randomly initialized ChaCha context.
