Firmware with speed optimizations is getting too big for self-extraction scheme.

boot mode detected (JTAG/SD) by reading hardware register
if JTAG, enter netboot, if SD read boot.bin
read runtime and bitstream from boot.bin or the network in SZL (move init_gateware() functionality to SZL)
read IP/MAC in SZL with the same code as the runtime
use protocol compatible with artiq_netboot
add auto-retry feature to artiq_netboot
update HITL test script to use artiq_netboot

szl: implemented #96 SZL no longer do self-extraction for runtime binary, it would boot from SD/ethernet depending on the boot mode settings. This allows a larger runtime binary, so we can optimize for speed in the runtime firmware for better performance, and allow more features to be added later.
