LICENSES: Add license text files, add missing notices, fix SPDX tags SPDX tags don't replace license files. Some notices were missing and some tags were not according to the SPDX specification, too. Now reuse --lint from the REUSE tool (https://reuse.software/) passes.

tcp: Add siphash implementation for initial sequence numbers Implement siphash routines for initial TCP sequence numbers (12 bytes input for IPv4, 36 bytes input for IPv6), and while at it, also functions we'll use later on for hash table indices and TCP timestamp offsets (with 8, 20, 32 bytes of input). Use these to set the initial sequence number, according to RFC 6528, for connections originating either from the tap device or from sockets.
