 * \brief Adjust TLS configuration
 *
 * Automatically enable certain dependencies. Generally, MBEDLTS_xxx
 * configurations need to be explicitly enabled by the user: enabling
 * MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a
 * compilation error. However, we do automatically enable certain options
 * in some circumstances. One case is if MBEDTLS_xxx_B is an internal option
 * used to identify parts of a module that are used by other module, and we
 * don't want to make the symbol MBEDTLS_xxx_B part of the public API.
 * Another case is if A didn't depend on B in earlier versions, and we
 * want to use B in A but we need to preserve backward compatibility with
 * configurations that explicitly activate MBEDTLS_xxx_A but not
 * MBEDTLS_xxx_B.
