66edeeb9c6 crypto: aes_init(): Fail correctly when called with bad key length 
A proper error code is returned if a key with unsupported (either by the implementation or the AES algorithm) length is passed to aes_init.
This fixes Issue #10175

crypto/modes/ccm: update internal functions to const input buffers 
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.

crypto/helper: Add secure wipe function 
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.

crypto/ccm: fix _fits_in_nbytes function 
Function is broken with num_bytes >= 4.

Could happen when storing input_len with len_encoding >= 4.
It can take values from 2 to 8, so make it work for cases it would overflow.

crypto/ccm: fix input_len check 
Maximum input_len depends only on length_encoding and not auth_data_len.
The current length_max value was also wrong.

RFC3610 page 2

   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.
