Add dedicated StreamBucket class (#13111)

RFC: https://wiki.php.net/rfc/dedicated_stream_bucket

Fix GH-13264: Part 1 - Memory leak on filter failure

Closes GH-13790

Remove unused stream filter resource name

Use new ZSTR_INIT_LITERAL macro (#10879)

Declare ext/standard constants in stubs - part 12 (#9729)

Use more compact representation for packed arrays.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[

Use more compact representation for packed arrays.

- 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.

Fixed bug #54350

Don't allow calling fclose() on the stream while in the user
filter callback. This is basically the same protection as xp_ssl
streams use during callback invocations.

There are more issues in this general area (e.g. stack overflow
on stream_filter_remove), but this addresses freeing the stream
during the filter callback invocation at least.

Make zend_call_function() failure handling consistent

This API had rather peculiar behavior in case the provided function
is not callable. For some types of failures, it would silently
return FAILURE (e.g. a function does not exist), while for others
(e.g. a class does not exist) it would generate a warning. Depending
on what the calling code does, this can either result in silent
failure or duplicate errors.

This commit switches the contract such that zend_call_function()
always (*) succeeds, though that success might be in the form of
throwing an exception. Calling a non-callable will now consistently
throw an exception.

There are some rare callers that do want to ignore missing methods,
for legacy APIs that are specific with optional methods. For these
use cases a new zend_call_method_if_exists() API is provided.

Calling code generally does not need to explicitly check for and
report zend_call_function() failures -- it can rely on
zend_call_function() having already done so. However, existing
code that does check for failure should continue to work fine.

(*) The only exception to this is if EG(active) being false during
late engine shutdown. This is not relevant to most code, but code
running in destructors and similar may need to be aware of the
possibility.

Fix check in user filter dtor

obj is always non-null, we need to check for UNDEF here.

This was caught by the new assertion introduced in

Declare php_user_filter::$stream property

This property is temporarily set during the filter() call. I have
no idea why this wasn't added as an argument to filter() instead.

pointer for destruction purposes. However, this is no longer used,

Replace zend_bool uses with bool

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
