01d4b76b7e Remove faulty cipher_finish calls from nist_kw 
The calls to cipher_finish didn't actually do anything:
- the cipher mode is always ECB
- in that case cipher_finish() only sets *olen to zero, and returns either 0
  or an error depending on whether there was pending data
- olen is a local variable in the caller, so setting it to zero right before
  returning is not essential
- the return value of cipher_finis() was not checked by the caller so that's
  not useful either
- the cipher layer does not have ALT implementations so the behaviour
  described above is unconditional on ALT implementations (in particular,
cipher_finish() can't be useful to hardware as (with ECB) it doesn't call any
functions from lower-level modules that could release resources for example)

Since the calls are causing issues with parameter validation, and were no
serving any functional purpose, it's simpler to just remove them.

2f6de42622 Move SHA256_VALIDATE[_RET] outside of MBEDTLS_SHA256_ALT guard 
Somehow, mbedtls_sha256_ret() is defined even if MBEDTLS_SHA256_ALT
is set, and it is using SHA256_VALIDATE_RET. The documentation should
be enhanced to indicate that MBEDTLS_SHA256_ALT does _not_ replace
the entire module, but only the core SHA-256 functions.

6af45ec53e PK: document context validity requirements 
Document when a context must be initialized or not, when it must be
set up or not, and whether it needs a private key or a public key will
do.

The implementation is sometimes more liberal than the documentation,
accepting a non-set-up context as a context that can't perform the
requested information. This preserves backward compatibility.

f25ee7f79d Fix parameter validation for mbedtls_mpi_lsb() 
The MPI_VALIDATE_RET() macro cannot be used for parameter
validation of mbedtls_mpi_lsb() because this function returns
a size_t.

Use the underlying MBEDTLS_INTERNAL_VALIDATE_RET() insteaed,
returning 0 on failure.

Also, add a test for this behaviour.

159171b72a PK parse/write: support keylen=0 correctly 
A 0-length buffer for the key is a legitimate edge case. Ensure that
it works, even with buf=NULL. Document the key and keylen parameters.

There are already test cases for parsing an empty buffer. A subsequent
commit will add tests for writing to an empty buffer.

e97dc60b42 Implement parameter validation in pk, pkparse and pkwrite 
Add checks for null pointers under MBEDTLS_CHECK_PARAMS.

In functions that perform operations with a context, only check if the
context pointer is non-null under MBEDTLS_CHECK_PARAMS. In the default
configuration, unconditionally dereference the context pointer.

In functions that query a context, support NULL as a
pointer-to-context argument, and return the same value as for a
context which has been initialized but not set up.

  recommended in private mode), so move the check to the
