Move cros_network_functions.cc to src/chromeos

Move cros_network_functions.cc to src/chromeos

We have some code that should be moved to src/content which needs to query network state (crbug.com/156428).

While we transition to the new network handlers, we will need to make Cros* calls when the --enable-new-network-handlers flag is not set.
To do that we need cros_network_functions.cc (and its dependencies) moved to src/chromeos, where they belong anyway.

gspencer@ - I'm moving these now because we don't want to wait until their
deprecated to migrate some code from src/chrome to src/content.

jam@ - These changes are almost the same as the ones in your large CL, plus a
bit of additional cleanup.

I split out some code that isn't shill/flimflam dependent into network_util so
that we can remove the cros_network_functions dependency in internet options,
and continue to use the Netmask code when we deprecate cros_network_functions.cc
