This changes ini_set() to accept all scalar types
(string|int|float|bool|null) for the new value. The idea here is
that while the INI system ultimately works with strings, its value
interpretation is designed to be consistent with PHP's casting rules,
e.g. "1" and "" are interpreted as boolean true and false respectively.
I personally believe that writing ini_set('precision', 10) makes more
sense than ini_set('precision', '10'), and find strict_types to be
unnecessarily pedantic here.

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.
Historically, the _ex variants separated the zval first, if a
conversion was necessary. This distinction no longer makes sense
since PHP 7.
The only difference that was still left is that _ex checked whether
the type is the same first, but the usage of these macros did not
actually distinguish on whether such an inlined check is valuable
or not in a given context.
Also drop the unused convert_to_explicit_type macros.
This exports a php_getenv() API which will fetch an environment
variable in a thread-safe manner (assuming all other environment
manipulations are thread-safe ... ha ha ha).
Closes GH-6571.
This macro is defined to zero as of PHP 5.0.0, and as the comment
indicates, is no longer relevant. Thus, we remove the definition and
all usages from the core and bundled extensions.
Closes GH-6351.
To make things a bit less weird, split off the function name into
a zval stored separately from the arguments. This allows us to
use normal zpp and get standard behavior.

Voidification of Zend API which always succeeded
Use bool argument types instead of int for boolean arguments
Use bool return type for functions which return true/false (1/0)
Use zend_result return type for functions which return SUCCESS/FAILURE as they don't follow normal boolean semantics
Closes GH-6002
Store the zend_string instead of performing a copy and storing
in a zval. Also make sure the string is released immediately if
it's no longer needed. Finally, avoid null pointer offset UB if
no string has been set -- though I'm wondering if this case
shouldn't be generating a warning?
From an engine perspective, named parameters mainly add three
concepts:
* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.

Add ZVAL_CHAR/RETVAL_CHAR/RETURN_CHAR as a shortcut for using
ZVAL_INTERNED_STRING and ZSTR_CHAR.
Add zend_string_init_fast() as a helper for the empty string /
one char interned string / zend_string_init() pattern.
Also add corresponding ZVAL_STRINGL_FAST etc macros.
Closes GH-5684.
This makes the zend_error_cb API simpler, and avoid formatting
the same message in multiple places.
It should be noted that the passed zend_string is always
non-persistent, so if you want to store it persistently somewhere,
you may still need to duplicate it.
The last_error_message is cleared a bit more aggressive, to make
sure it doesn't hang around across allocator life-cycles.
Closes GH-5639.
Treatment of locales in PHP is currently inconsistent: The LC_ALL
locale is set to "C", as is standard behavior on program startup.
The LC_CTYPE locale is set to "", which will inherit it from the
environment. However, the inherited LC_CTYPE locale will only be
used in some cases, while in other cases it is necessary to perform
an explicit setlocale() call in PHP first. This is the case for
the locale-sensitive handling in the PCRE extension.
Make things consistent by *never* inheriting any locales from the
environment. LC_ALL, including LC_CTYPE will be "C" on startup.
A locale can be set or inherited through an explicit setlocale()
call, at which point the behavior will be fully consistent and
predictable.
Closes GH-5488.
If @generate-function-entries is specified in the stub file,
also generate function entries for the extension.
Currently limited to free functions only.
