This commit switches UID hashing from md5 to a highway hash. It also
moves the salt value out of the file plugin - and makes it
installation-specific instead - it is moved to the global namespace.
There now are digest hash functions to make "static"
installation-specific hashes that are stable over workers available to
everyone; hashes can be 64, 128 or 256 bits in size.
Due to the fact that we switch the file hashing algorithm, all file
hashes change.
The underlyigng algorithm that is used for hashing is highwayhash-128,
which is significantly faster than md5.

Add linux netfilter NFLOG capture functionality initial commit
I made modifications:
- Formatting / code style
- More error handling and validity checks
- The Type and Length value of TLVs is technically host order
- Changed / fixed the Length value padding check: it's generally
32-bit alignment, not just aligning any TLV less than 8 bytes.
