/**
 * @defgroup altcp_api Application layered TCP Introduction
 * @ingroup callbackstyle_api
 *
 * Overview
 * --------
 * altcp (application layered TCP connection API; to be used from TCPIP thread)
 * is an abstraction layer that prevents applications linking hard against the
 * @ref tcp.h functions while providing the same functionality. It is used to
 * e.g. add SSL/TLS (see LWIP_ALTCP_TLS) or proxy-connect support to an application
 * written for the tcp callback API without that application knowing the
 * protocol details.
 *
 * * This interface mimics the tcp callback API to the application while preventing
 *   direct linking (much like virtual functions).
 * * This way, an application can make use of other application layer protocols
 *   on top of TCP without knowing the details (e.g. TLS, proxy connection).
 * * This is achieved by simply including "lwip/altcp.h" instead of "lwip/tcp.h",
 *   replacing "struct tcp_pcb" with "struct altcp_pcb" and prefixing all functions
 *   with "altcp_" instead of "tcp_".
 *
 * With altcp support disabled (LWIP_ALTCP==0), applications written against the
 * altcp API can still be compiled but are directly linked against the tcp.h
 * callback API and then cannot use layered protocols. To minimize code changes
 * in this case, the use of altcp_allocators is strongly suggested.
 *
 * Usage
 * -----
 * To make use of this API from an existing tcp raw API application:
 * * Include "lwip/altcp.h" instead of "lwip/tcp.h"
 * * Replace "struct tcp_pcb" with "struct altcp_pcb"
 * * Prefix all called tcp API functions with "altcp_" instead of "tcp_" to link
 *   against the altcp functions
 * * @ref altcp_new (and @ref altcp_new_ip_type/@ref altcp_new_ip6) take
 *   an @ref altcp_allocator_t as an argument, whereas the original tcp API
 *   functions take no arguments.
 * * An @ref altcp_allocator_t allocator is an object that holds a pointer to an
 *   allocator object and a corresponding state (e.g. for TLS, the corresponding
 *   state may hold certificates or keys). This way, the application does not
 *   even need to know if it uses TLS or pure TCP, this is handled at runtime
 *   by passing a specific allocator.
 * * An application can alternatively bind hard to the altcp_tls API by calling
 *   @ref altcp_tls_new or @ref altcp_tls_wrap.
 * * The TLS layer is not directly implemented by lwIP, but a port to mbedTLS is
 *   provided.
 * * Another altcp layer is proxy-connect to use TLS behind a HTTP proxy (see
 *   @ref altcp_proxyconnect.h)
 *
 * altcp_allocator_t
 * -----------------
 * An altcp allocator is created by the application by combining an allocator
 * callback function and a corresponding state, e.g.:\code{.c}
 * static const unsigned char cert[] = {0x2D, ... (see mbedTLS doc for how to create this)};
 * struct altcp_tls_config * conf = altcp_tls_create_config_client(cert, sizeof(cert));
 * altcp_allocator_t tls_allocator = {
 *   altcp_tls_alloc, conf
 * };
 * \endcode
 *
 *
 * struct altcp_tls_config
 * -----------------------
 * The struct altcp_tls_config holds state that is needed to create new TLS client
 * or server connections (e.g. certificates and private keys).
 *
 * It is not defined by lwIP itself but by the TLS port (e.g. altcp_tls to mbedTLS
 * adaption). However, the parameters used to create it are defined in @ref
 * altcp_tls.h (see @ref altcp_tls_create_config_server_privkey_cert for servers
 * and @ref altcp_tls_create_config_client/@ref altcp_tls_create_config_client_2wayauth
 * for clients).
 *
 * For mbedTLS, ensure that certificates can be parsed by 'mbedtls_x509_crt_parse()' and
 * private keys can be parsed by 'mbedtls_pk_parse_key()'.
