ed59dc1ada Prevented a race condition between a new ARP request and the ARP timer. 
Timeouts stay the same (halved the ARP timer, doubled the counts), but
ETHARP_MAX_PENDING should be at least 2 to prevent it from reaching 0 right away,
giving too little time for any ARP responses to be noted.

* etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
    Do not try hard to insert arbitrary packet's source address,
    etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
    etharp_query() now always DOES call ETHARP_TRY_HARD so that users
    querying an address will see it appear in the cache (DHCP could
    suffer from this when a server invalidly gave an in-use address.)

751557bcbf 16th October 2004 - Kieran Mansley - kjm25@cam.ac.uk 
- Add code to tcp_recved() to send an ACK (window update)
immediately, even if one is already pending, if the rcv_wnd is above a
threshold (currently TCP_WND/2)
 - This avoids waiting for a timer to expire to send a delayed ACK in
order to open the window if the stack is only receiving data.
