Check PB flag to see whether timestamp and data headers are present.
Check bounds before accessing data. Bump handle_str length to fit
maximum.
Byteswap length values, and mask Packet_Status_Flag correctly. Remove
SDU length check, as we are not tracking fragmentation.
Fixes: https://github.com/bluez/bluez/issues/2292
