* These are the general TLV (un)packing routines.
*
* Data is Serialised into the following format
*
* -----------------------------------------
* | TLV TYPE (2 bytes) | TLV LEN (4 bytes)|
* -----------------------------------------
* | |
* | Data .... |
* | |
* -----------------------------------------
*
* Originally TLV TYPE = 2 bytes, and TLV LEN = 2 bytes.
* However with HTML and WSTRINGS the 64K Limit becomes limiting.
* The TLV LEN = 4 bytes now!
*
* Size is the total size of the TLV Field (including the 4 byte header)
*
* Like the lowlevel packing routines. They are usually
* created in pairs - one to pack the data, the other to unpack.
*
* GetTlvXXX(void *data, uint32_t size, uint32_t *offset, XXX *out);
* SetTlvXXX(void *data, uint32_t size, uint32_t *offset, XXX *in);
*
*
* data - the base pointer to the serialised data.
* size - size of the memory pointed to by data.
* *offset - where we want to (un)pack the data.
* This is incremented by the datasize.
*
* *in / *out - the data to (un)pack.
