Add FNV-128 hash for legacy symbol mangling
Rustc uses a SIP128 hash for the legacy symbol mangling but an FNV hash is
simpler to implement this is a port of the implementation from golang
stdlib hash package.
The fingerprint for the hash is simple the function signiture for now.
Rustc takes into account options such as -Cmetadata to generate uniqueness.
We still need to implement an SIP128 and the V0 symbol mangling but this
will do in the interim.
Addresses: #305
Fixes: #428
