* OctoClock can communicate with UHD over Ethernet
* Can read NMEA strings from GPSDO and send to host
* Added multi_usrp_clock class for clock devices
* uhd::device can now filter to return only USRP devices or clock devices
* New OctoClock bootloader can accept firmware download over Ethernet
* Added octoclock_burn_eeprom,octoclock_firmware_burner utilities
* Added test_clock_synch example to show clock API
* New method: --values="key1=value1,key2=value2"
* To read key2: --values="key1=value1,key2,key3=value2"
* Added --read-all option to read all values in EEPROM without burning
* Old arguments still work but print deprecation warning
Conflicts:
host/docs/usrp_x3x0.rst
* example: usrp_burn_mb_eeprom --key="name,ip-addr" --val="my_usrp,192.168.10.3"
* As before, omitting the --val argument will just read off all named keys
* If number of given keys and vals don't match, the util will throw an error
