26ab5dd7a7 A Proper lookup table that uses HashTable's API
This is the first step of allowing heterogeneous cells in hash tables.

performance test results are

```

1. HashMap<UInt16, UInt8, TrivialHash, HashTableFixedGrower<16>>;
2. NewLookupMap<UInt16, UInt8>

Merge pull request #4466 from danlark1/master
Function trigramDistance() added for string similarity search

b94de32423 Support xxHash with external lz4
xxhash.h does not exist in external lz4 because it is an implementation detail
and its symbols are namespaced with XXH_NAMESPACE macro.  When lz4 is external,
xxHash has to be external too, and the dependents have to link to it.

This find_xxhash.cmake is based on find_lz4.cmake.
