Same as already done for libosmo-ranap.
This allows applications setting the cateogy dynamically, and will allow
untangling library tests using hnbgw log categories in this repo.
Change-Id: I5d09b67b115ad8938e5162a23accfcbafab139d4
We can now send Iuh messages with commands like 'hnbap hnb register',
'hnbap ue regiter imsi 12345', 'ranap reset cs', 'ranap reset ps',
and even establish connection-oriented RUA using
'channel cs lu imsi 12345'
