soloscli: allow user to apply settings to solos h/w before bringing up network (patch by Philip Prindeville)

If the network/wan configuration contains "solos0" ... "solos3" then this list of strings will be applied to the FPGA when the hardware is hotplug added.

The syntax should be "tag=value", as per the values enumerated in the solos-attr.c list.

In the canned example, the modem is temporarily turned off, told to detect noise, told to disable annexes M and A (effectively putting it into pure ADSL mode), and re-activated.

There's probably a more appropriate function name than "dialog" but that's what I came up with.

Handle other ATM hardware (Eagle, etc) besides solos-pci.
