hnb-test: decode NAS pdu when receiving RUA from CN

hnb-test: simplify crossing message layers Adding the Security Mode Control command would break the current scheme of callbacks across layers. This brought to my attention that the scheme is indeed unnecessarily complex, so simplify it. Instead of passing callbacks, call functions directly. Add hnb-test-layers.h to declare those functions that cross from main to rua, to ranap and back to main and remove the callback type definitions. Instead of copying the NAS PDU to a newly allocated msgb, pass the data and len directly to hnb_test_nas_rx_dtap(). Instead of repeatedly checking the gsm48_hdr length, just pass the struct gsm48_hdr* and len around and assume the basic header length has been checked. In some places, rename 'length' to 'len' for cosmetic consistency.
