mbedtls_x509_free_subject_alt_name() function

SAN structure - extra memory owned by this structure will be freed

This function parses an item in the SubjectAlternativeNames extension. Please note that this function might allocate additional memory for a subject alternative name, thus mbedtls_x509_free_subject_alt_name has to be called to dispose of this additional memory afterwards. \warning The target structure contains pointers to the raw data of the parsed certificate, and its lifetime is restricted by the lifetime of the certificate.
