* stp: select the root port by cost and block redundant links * stp: move the protocol to BANK4 and keep the command line in BANK2 * stp: implement the RSTP state machines of 802.1D-2004 clause 17 * stp: counters, more settings and a fuller Spanning Tree page * stp: make a link aggregation group one port of the RSTP tree * web: serve the Spanning Tree JSON from BANK4 as well Kept in BANK1, the larger Spanning Tree page would leave under 1 kB there for the rest of the web server and every page still to come, so send_stp() and send_stp_counters() move to httpd/page_stp.c in BANK4 with the protocol, as banked calls, with their own copies of the few output helpers and of the JSON header, so nothing in BANK4 calls into BANK1 directly or hands it a pointer into its code space. BANK4 takes the free flash between BANK3 and the web files. KP_9000_6XHML_X2: BANK1 44336, BANK2 36969, BANK3 11942, BANK4 20965 bytes of 49152.
