The initialization routine for XXH3 was not prepared for exceptions from seed.
Fix this by using try_convert_to_string.

@cname currently refers to the constant name in C. However, it is not always a (constant) name, but sometimes a function invocation, so naming it as @cvalue would be more appropriate.
Nothing new but to refactor usage b/w hash and password
extensions but using volatile pointers to be a bit safer,
allowing to expand its usage eventually.
We must not allow to serialize already finalized `HashContext`s, since
the internal context is already freed. Since there is not much point
in serializing finalized `HashContext`s, we just bail out in that case.
Closes GH-8265.
Like `hash_file()`, `hash_hmac_file()` expects a filename, and not some
string data. Fixing this now, constitutes a (hopefully small) BC break
though.
Closes GH-7828.
`hash()` and `hash_hmac()` never return `false`; only `hash_file()` and
`hash_hmac_file()` return `false` in case the data cannot be read.
Closes GH-7760.
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
Deprecate mhash(), mhash_keygen_s2k(), mhash_count(),
mhash_get_block_size() and mhash_get_hash_name() in favor of the
normal hash_*() functions.

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

A secret can be passed through the options array. The length is
currently in the range of 136 to 256 bytes. The concerned algos are
already marked as non serializable.

This deprecates passing null to non-nullable scale arguments of
internal functions, with the eventual goal of making the behavior
consistent with userland functions, where null is never accepted
for non-nullable arguments.
This change is expected to cause quite a lot of fallout. In most
cases, calling code should be adjusted to avoid passing null. In
some cases, PHP should be adjusted to make some function arguments
nullable. I have already fixed a number of functions before landing
this, but feel free to file a bug if you encounter a function that
doesn't accept null, but probably should. (The rule of thumb for
this to be applicable is that the function must have special behavior
for 0 or "", which is distinct from the natural behavior of the
parameter.)

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
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.
