Harald Welte 96c61074f5 tlv_parser: Fix various out-of-bounds accesses 
The libosmocore TLV parser had a number of insufficient bounds checks
leading to reads beyond the end of the respective input buffer.

This patch
* adds proper out-of-bounds checks to all TLV types
* simplifies some of the existing checks
* introduces test cases to test all the corner cases
  where either TAG, or length, or value are not fully contained
  in the input buffer.

Thanks to Ilja Van Sprundel for reporting these problems.
