hnbgw: Bring all parts together
...
We now have the RUA and SUA parts interconnected by the
context ID mapper, and should be able to pass messages back and forward
between both sides.
Unfortunately this touches a bit of everything, but the structures are
all still very much in flux. Hopefully they will start to stabilize at
some point soon...

asn1helpers: Fix 24 bit conversion function and use it in hnbgw_hnbap
...
The 32 bit int needs to be shifted left one byte so the correct bytes
end up at the beginning of the bit string buffer.

asn1helpers: Add 28 bit conversion function and use it for Cell ID
...
The padding bits in the bit string are at the end and the byte-order is
MSB-first. This means the number needs to be shifted left so the padding
bits are the least significant.
