hash: Implement xxHash
The implementation bundles the xxHash v0.8.0 release and includes all the variants
- xxh32, 32-bit wide
- xxh64, 64-bit wide
- xxh3, 64-bit wide
- xxh128, 128-bit wide
An initial hash state can be passed through the options arrray. An additional
functionality not targeted in this implementation is the secret support in xxh3
and xxh128. That can be added at a later point.
The serialization for xxh3 and xxh128 should not be implemented, as the
state would contain the secret. Despite the xxHash is a non crypto
algorithm, the secret would be serialized as plain text which would be
insecure.

hash: Add MurmurHash3 with streaming support
The implementation is based on the upstream PMurHash. The following
variants are implemented
- murmur3a, 32-bit hash
- murmur3c, 128-bit hash for x86
- murmur3f, 128-bit hash for x64
The custom seed support is not targeted by this implementation. It will
need a major change to the API, so then custom arguments can be passed
through `hash_init`. For now, the starting hash is always zero.
Fixes bug #68109, closes #6059

Correct implementation of joaat hash.
Before this commit, the result produced by a joaat hash depended
on how the input data was chunked. A hash produced by multiple
`hash_update` operations was incorrect. For example, this code,
which should produce three identical lines:
var_dump(hash("joaat", "abcd"));
$hash = hash_init("joaat");
hash_update($hash, "ab");
hash_update($hash, "cd");
var_dump(hash_final($hash));
$hash = hash_init("joaat");
hash_update($hash, "abc");
hash_update($hash, "d");
var_dump(hash_final($hash));
instead produced:
string(8) "cd8b6206"
string(8) "e590d137"
string(8) "2d59d087"
This is because the finalization step, involving shift operations
and adds, was applied on every chunk, rather than once at the end
as is required by the hash definition.
After this commit, the code above produces:
string(8) "cd8b6206"
string(8) "cd8b6206"
string(8) "cd8b6206"
as expected.
Some tests encoded the wrong behavior and were corrected.
Closes GH-5749

Use EXPECT instead of EXPECTF when possible
EXPECTF logic in run-tests.php is considerable, so let's avoid it.
