The mbed TLS library has introduced some changes in the API from the 1.3.x to the 2.x releases. Using the 2.x releases requires some changes to the crypto and transport modules. This patch updates both modules to the mbed TLS 2.x API. All references to the mbed TLS library in the code or documentation have been updated to 'mbed TLS'. Old references to PolarSSL have been updated to 'mbed TLS'. User guide updated to use mbed TLS 2.2.0. NOTE: moving up to mbed TLS 2.x from 1.3.x is not backward compatible. Applying this patch will require an mbed TLS 2.x release to be used. Also note that the mbed TLS license changed to Apache version 2.0. Change-Id: Iba4584408653cf153091f2ca2ee23bc9add7fda4
