Sebastien Bourdeauducq f2911d67b7 Enable TCP keepalive on the core device 
Automatically runs the idle experiment a few seconds after the master stops responding.

Thanks Florent for figuring out TCP_KEEPIDLE_DEFAULT needed to be set in addition to the other options.

Closes #31

Robert Jördens 67715f0d2e pipistrello: only put serdes on the lower ttls 
this setup is getting a bit power hungry.

pmt0, 1 (rtio channels 0, 1): 4x in and out
ttl0, 1 (rtio channels 2, 3): 4x out
ttl2 (rtio channel 4): 8x out

Robert Jördens 9dfbf07743 pipistrello: use 4x serdes for rtio ttl 
pipistrello: do not wait for lock on startup

LCK_cycle:6 was added in 6a412f796e1 (mibuild). It waits for _all_
DCM and PLLs to lock (probably irrespective of STARTUP_WAIT).
