murmurhash: always load byte by byte
...
Also reverse the order of bytes, loading the most significant parts first,
and use bitwise "or" instead of addition.

Fix murmurhash for big-endian architectures.
...
The murmurhash implementation tries to read a sequence of four bytes as
a single little-endian uint32 value. This does not work on e.g. Linux/s390x;

Support opening files bigger than 2 GiB
...
The real technical limit is with lines bigger than 2 GiB and buffers
with more than 2 Gi lines, refactor buffer loading to make it possible
to load those files.
Fix an overflow with the hash_data function at the same time

Rework hashing, use a more extensible framework similar to n3876 proposal
...
std::hash specialization is a pain to work with, stop using that, and
just specialize a 'size_t hash_value(const T&)' free function.
