5a3c50e890 Don't use an enum in a bit-field
This isn't standard C. GCC and Clang accept it but not every
compiler (e.g. Armcc 5).

b0b189f31f Add missing compilation guards for GCM and CCM
Add missing compilation guards that broke the build if either GCM or
CCM was not defined.

Add missing guards on test cases that require GCM or CBC.

The build and tests now pass for any subset of {MBEDTLS_CCM_C,
MBEDTLS_GCM_C}. There are still unused variables warnings if neither
is defined.

5e76952235 Add a facility to configure entropy sources
Add a function to configure entropy sources. For testing only.

Use it to test that the library initialization fails properly if there is no
entropy source.

82df32e3fd psa: Unused key_bits is OK
When MD or CMAC are disabled, let the compiler know that it is OK that
`key_bits` is set but not used by casting `key_bits` to `(void)`.

3016de3eeb pk_wrap: rework signature extraction to work with small r and s values
There is a probability that r will be encoded as 31 or less bytes in DER,
so additional padding is added in such case.
Added a signature-part extraction function to tidy up the code further.

6f249de706 pkwrite: add opaque key handling for public key exporting
Return early from mbedtls_pk_write_pubkey_der - public opaque key
exporting is expected to contain all of the needed data, therefore it shouldn't
be written again.

29a1325b0d Guard against PSA generating invalid signature
The goal is not to double-check everything PSA does, but to ensure that it
anything goes wrong, we fail cleanly rather than by overwriting a buffer.

276cb64e6c Align names to use "opaque" only everywhere
It's better for names in the API to describe the "what" (opaque keys) rather
than the "how" (using PSA), at least since we don't intend to have multiple
function doing the same "what" in different ways in the foreseeable future.

07b103fe07 Implement can_do for opaque ECC keypairs
Unfortunately the can_do wrapper does not receive the key context as an
argument, so it cannot check psa_get_key_information(). Later we might want to
change our internal structures to fix this, but for now we'll just restrict
opaque PSA keys to be ECDSA keypairs, as this is the only thing we need for
now. It also simplifies testing a bit (no need to test each key type).

fc20c14e76 Use PSA-based ciphers for record protections in TLS-1.2 only
Reasons:
- For the first release, we attempt to support TLS-1.2 only,
- At least TLS-1.0 is known to not work at the moment, as
  for CBC ciphersuites the code in mbedtls_ssl_decrypt_buf()
  and mbedtls_ssl_encrypt_buf() assumes that mbedtls_cipher_crypt()
  updates the structure field for the IV in the cipher context,
  which the PSA-based implementation currently doesn't.
