With UIP_CONF_MAX_CONNECTIONS set to one, a verified upload can leave
reset intent set when its response is never acknowledged. A subsequent
TCP connection reuses that slot, and ACKing its plain GET response can
otherwise trigger reset_chip(). This is sequential slot reuse, not
concurrent HTTP connections.
Store reset intent in the connection appstate and initialize both tstate
and fw_reset_pending on every uip_connected() event, regardless of stale
appstate contents. Reset only after the verified upload response is fully
acknowledged.
Exercise the real HTTP callback for all stale tstate bytes, sequential
slot reuse and a later GET, partial/final ACKs, abort, timeout and CRC
failure. Keep the regression tests in the existing tab-indented style.
