abis_nm: Add support to parse some nanoBTS Attribute Response attributes
nanoBTS actually supports regular formatting. There are a few differences
with spec though:
* The attributes are listed directly in the message instead of being inside
the Get Attributes Response Info after the unsupported attribute ID list.
* The Get Attributes Response Info can be at any position in the
attribute list, and it only contains the unsupported attribute ID list.
As a result, parsing is currently split into 3 main parts or functions:
* Parsing regular (per spec) Get Attributes Response Info attr and get a
pointer to the list of attributes.
* A function that parses the list of attributes, called directly in case
of nanoBTS, and called by the former parser of Get Attributes Response
Info for regular (per spec) OML endpoints.
* A function to parse the unsupported attribute ID list, also used in the
first function to get a pointer to the list of attributes.
