davidhaas 6929a67489 Add the following features and bugfixes: ... Added select() functionality to sockets library. Support for errno in sockets library. Byte ordering fixes. basic lwip_ioctl(), FIONREAD, get/setsockopt() etc. support - added additional argument to netif_add to pass state pointer so that the if_init function has access to context information before the interface is added, without accessing globals. - added netif_remove() - to conserve cpu load the tcpip_tcp_timer should only be active when tcbs that need it exist. - pass length of available data to callbacks for NETCONN_EVT_RCV events - added tcpip_link_input(), a hack to allow processing of PPP packets in tcpip_thread() context. This saves threads and context switches. - renamed incompatible ASSERT() macro to LWIP_ASSERT() to avoid name collision. - changed a bunch of %d's to %u's in format strings for unsigned values. - added ip_frag to lwip_stats. - changed IP_REASS_MAXAGE and IP_REASS_TMO defaults to more realistic values. - added sys_timeout_remove() function to cancel timeouts (needed by PPP amongst other things). - tolerate NULL returns from sys_arch_timeouts() since some threads might not need to use or have timeouts. - added sys_sem_wait_timeout() - moved mem_malloc() function to end of mem.c to work around tasking compiler bug. - automatically bind to local tcp port if 0. - allow customization of port ranges for automatic local bindings. - corrected various typos, spelling errors, etc.. Thanks to Marc Boucher for many of these changes.		2003-02-06 22:18:30 +00:00
