aa3ed6f987 Make RNG parameters mandatory in ECP functions
Fix trivial faulty calls in ECP test suite and ECP/ECJPAKE self-tests (by
adding a dummy RNG).

Several tests suites are not passing yet, as a couple of library
function do call ecp_mul() with a NULL RNG. The complexity of the fixes
range from "simple refactoring" to "requires API changes", so these will
be addressed in separate commits.

This makes the option MBEDTLS_ECP_NO_INTERNAL_RNG, as well as the whole
"internal RNG" code, obsolete. This will be addressed in a future
commit, after getting the test suites to pass again.

f035904060 Check for mandatory RNG parameters in RSA private
(This commit is best reviewed using `git show -b` as indentation levels
have changed.)

The documentation already states that the RNG parameter is mandatory,
since PRs #4488 and #4515. There are several families of functions to
consider here:

- private-key operations (sign, decrypt) all call
mbedtls_rsa_private() where this commit adds a non-NULL check;
- encrypt operations need an RNG for masking/padding and already had a
non-NULL check since #4515 (conditional on \p mode before that)
- verify operations no longer take an RNG parameter since #4515

So, after this commit, all RSA functions that accept an RNG will reach a
non-NULL check before the RNG is used.

e5702489f5 mbedtls_dhm_get_value parameter order: context first, output last
mbedtls_dhm_get_value can be seen as either a copy function or a getter
function. Given the name and the semantics, it's more of a getter, even if
it "gets" by doing a copy. Therefore, put the context first, and the
selector next, leaving the output for last.

5c3f18d37c MBEDTLS_PK_PARSE_EC_EXTENDED is incompatible with MBEDTLS_ECP_ALT
... unless the alt implementation defines a group structure that's mostly
compatible with the built-in one and supports partially filled group
structures in the same way.

It would be possible to rewrite the SpecifiedECDomain parsing code to avoid
requiring support for partially filled group structures, but that's too
complicated to do now.

487bbf6805 DHM: new functions to query the length of the modulus
Add two functions mbedtls_dhm_get_len() and mbedtls_dhm_get_bitlen() to
query the length of the modulus in bytes or bits.

Remove the len field: the cost of calling mbedtls_dhm_get_len() each time
it's needed is negligible, and this improves the abstraction of the DHM
module.
