mwojcik	c834e4f503	enable network and mgmt during Rust panic, make RTIO PLL lock failure a panic Closes #198 #200 Making it a soft panic makes it more involved with a bit of code duplication - setting up mgmt requires setting up the interface and sockets. Maybe can be done a bit cleaner. ``` [spaqin@hera:~/m-labs/artiq-zynq]$ artiq_sinara_tester **** Sinara system tester **** [...] ConnectionRefusedError: [Errno 111] Connection refused [spaqin@hera:~/m-labs/artiq-zynq]$ artiq_coremgmt -D 192.168.1.56 log [ 0.000067s] INFO(runtime): NAR3/Zynq7000 starting...
