Most TLVs in the oscar protocol are big endian, which is why the TLV functions
in tlv.c are big endian. The SNACs in the 0x0015 family are the only ones
that use little endian order, and I guess the author of that code chose to not
write tlv helper functions for little endian tlvs (possibly in the hopes that
the hacky ICQ protocol extensions would disappear).
