Remove most of the doxygen mainpage

Since the API docs are now published as part of the larger
documentation, it makes no sense to give an overview of Mbed TLS in the
mainpage as this is already given elsewhere.

- * mbed TLS has a simple setup: it provides the ingredients for an SSL/TLS
- * implementation. These ingredients are listed as modules in the
- * \ref mainpage_modules "Modules section". This "Modules section" introduces
- * the high-level module concepts used throughout this documentation.\n
- * Some examples of mbed TLS usage can be found in the \ref mainpage_examples
- * "Examples section".

- * @section mainpage_modules Modules

- * mbed TLS supports SSLv3 up to TLSv1.2 communication by providing the
- * following:
- * - TCP/IP communication functions: listen, connect, accept, read/write.
- * - SSL/TLS communication functions: init, handshake, read/write.
- * - X.509 functions: CRT, CRL and key handling
- * - Random number generation
- * - Hashing
- * - Encryption/decryption
- *
- * Above functions are split up neatly into logical interfaces. These can be
- * used separately to provide any of the above functions or to mix-and-match
- * into an SSL server/client solution that utilises a X.509 PKI. Examples of
- * such implementations are amply provided with the source code.
- *
- * Note that mbed TLS does not provide a control channel or (multiple) session
- * handling without additional work from the developer.

- * Example server setup:
- *
- * \b Prerequisites:
- * - X.509 certificate and private key
- * - session handling functions
- *
- * \b Setup:
- * - Load your certificate and your private RSA key (X.509 interface)
- * - Setup the listening TCP socket (TCP/IP interface)
- * - Accept incoming client connection (TCP/IP interface)
- * - Initialise as an SSL-server (SSL/TLS interface)
- *   - Set parameters, e.g. authentication, ciphers, CA-chain, key exchange
- *   - Set callback functions RNG, IO, session handling
- * - Perform an SSL-handshake (SSL/TLS interface)
- * - Read/write data (SSL/TLS interface)
- * - Close and cleanup (all interfaces)
- *
- * Example client setup:
- *
- * \b Prerequisites:
- * - X.509 certificate and private key
- * - X.509 trusted CA certificates
- *
- * \b Setup:
- * - Load the trusted CA certificates (X.509 interface)
- * - Load your certificate and your private RSA key (X.509 interface)
- * - Setup a TCP/IP connection (TCP/IP interface)
- * - Initialise as an SSL-client (SSL/TLS interface)
- *   - Set parameters, e.g. authentication mode, ciphers, CA-chain, session
- *   - Set callback functions RNG, IO
- * - Perform an SSL-handshake (SSL/TLS interface)
- * - Verify the server certificate (SSL/TLS interface)
- * - Write/read data (SSL/TLS interface)
- * - Close and cleanup (all interfaces)
