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.

Closes GH-6524

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

Sync HAVE_HASH, HAVE_HASH_EXT, PHAR_HASH_OK symbols

The hash extension is always available since PHP-7.4. The symbol
HAVE_HASH_EXT is kept for BC reasons and removed in PHP-8.0.

Sync leading and final newlines in source code files

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

Sync leading and final newlines in source code files

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
