Changes
* The ECP module, enabled by `MBEDTLS_ECP_C`, now depends on
`MBEDTLS_CTR_DRBG_C`, `MBEDTLS_HMAC_DRBG_C`, `MBEDTLS_SHA512_C` or
`MBEDTLS_SHA256_C` for some side-channel coutermeasures. If side channels
are not a concern, this dependency can be avoided by enabling the new
option `MBEDTLS_ECP_NO_INTERNAL_RNG`.
Security
* Fix side channel in mbedtls_ecp_check_pub_priv() and
mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a
private key that didn't include the uncompressed public key), as well as
mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL
f_rng argument. An attacker with access to precise enough timing and
memory access information (typically an untrusted operating system
attacking a secure enclave) could fully recover the ECC private key.
Found and reported by Alejandro Cabrera Aldaya and Billy Brumley.

Security
* Fix issue in Lucky 13 counter-measure that could make it ineffective when
hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT
macros). This would cause the original Lucky 13 attack to be possible in
those configurations, allowing an active network attacker to recover
plaintext after repeated timing measurements under some conditions.
Reported and fix suggested by Luc Perneel in #3246.

/**
* \def MBEDTLS_ECP_NO_INTERNAL_RNG
*
* When this option is disabled, mbedtls_ecp_mul() will make use of an
* internal RNG when called with a NULL \c f_rng argument, in order to protect
* against some side-channel attacks.
*
* This protection introduces a dependency of the ECP module on one of the
* DRBG or SHA modules (HMAC-DRBG, CTR-DRBG, SHA-512 or SHA-256.) For very
* constrained applications that don't require this protection (for example,
* because you're only doing signature verification, so not manipulating any
* secret, or because local/physical side-channel attacks are outside your
* threat model), it might be desirable to get rid of that dependency.
*
* \warning Enabling this option makes some uses of ECP vulnerable to some
* side-channel attacks. Only enable it if you know that's not a problem for
* your use case.
*
* Uncomment this macro to disable some counter-measures in ECP.

* Currently ecp_mul() takes a RNG function as an argument, used for
* side-channel protection, but it can be NULL. The initial reasoning was
* that people will pass non-NULL RNG when they care about side-channels, but
* unfortunately we have some APIs that call ecp_mul() with a NULL RNG, with
* no opportunity for the user to do anything about it.
*
* The obvious strategies for addressing that include:
* - change those APIs so that they take RNG arguments;
* - require a global RNG to be available to all crypto modules.
*
* Unfortunately those would break compatibility. So what we do instead is
* have our own internal DRBG instance, seeded from the secret scalar.
*
* The following is a light-weight abstraction layer for doing that with
* HMAC_DRBG (first choice) or CTR_DRBG.
