layer23 manual network search: Fixed searching behavior.

First of all I cleaned up the VTY commands. Instead of something like
"barred-access (yes|no)", I use now "barred-access" and "no barred-access".
Your stored configuration file will not load, because config format has
changed. Just remove the lines that cannot be parsed by VTY from your
config. Then the default values are used on next startup. Modify these as
desired via VTY using the new commands.

Use "rplmn <mcc> <mnc>" or "no rplmn" to set the initial behaviour of
network search. If RPLMN is set, this network is selected. If it is not
found, it will be displayed, then it is time to do a search
"network search 1".

If you have set "no rplmn" the search is started automatically on power on.
After the search you can see available networks and show the cells using
"show cell 1" or the detailed information "show cell 1 <arfcn>".

For testing all that be sure to set the "sim" to "test" and the
"network-search" to "manual". Do "show run" to see all commands to be set.
