Input buffers are not modified, so can be declared const arguments.
This will allow using `const` inputs for `modes/ccm`.
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.

The current length_max value was also wrong.

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.

`memcpy()` must not be used if the input and output ranges overlap,
because it is undefined if the data if copied from front to the end or
vice versa.
