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.
