Fix GH-9883 SplFileObject::__toString() reads next line

We need to overwrite the __toString magic method for SplFileObject, similarly to how DirectoryIterator overwrites it
Moreover, the custom cast handler is useless as we define __toString methods, so use the standard one instead.

Declare ext/spl constants in stubs (#9226)

Update gen_stub to support #if around classes

Remove internal usage of SplFileInfo::_bad_state_ex() method (#8318)

* Use standard VM handling instead
* Deprecate the method as it is now useless

Fix generation of arginfo if type is just null

Use more specific return types in SPL

Make DirectoryIterator current() / key() return types tentative

Fixes GH-8192.

Add ZEND_ACC_NOT_SERIALIZABLE flag

This prevents serialization and unserialization of a class and its
children in a way that does not depend on the zend_class_serialize_deny
and zend_class_unserialize_deny handlers that will be going away
in PHP 9 together with the Serializable interface.

In stubs, `@not-serializable` can be used to set this flag.

This patch only uses the new flag for a handful of Zend classes,
converting the remainder is left for later.

Closes GH-7249.
Fixes bug #81111.

SplFileObject::fgetcsv(): Consistently return false on failure

Both the documentation and the stubs state that this method is
supposed to return false on failure. However, if the line read
(rather than the getcsv operation) fails, it would incorrectly
return null instead.

Fix #42357: fputcsv() has an optional parameter for line endings

fputcsv does not terminate lines correctly as per RFC 41801[1]. After adding a new parameter fputcsv may now use a user defined line ending,. In order to maintain backwards compatibility fputcsv() still terminates lines with "\n" by default.

Generate ext/spl class entries from stubs

Closes GH-6709

SplFileObject::fgets() cannot return false

spl_filesystem_file_read() is called with silent=0, so it will
throw on failure.

Update ext/spl parameter names

Closes GH-6284.

Add support for `@implementation-alias` in stubs

Display types in stubs more uniformly

In preparation for generating method signatures for the manual.

This change gets rid of bogus false|null return types, a few unnecessary trailing backslashes, and settles on using ? when possible for nullable types.

Return empty string from SplFileInfo::getPathname()

Instead of false. This is consistent with how other methods like
SplFileInfo::getPath() behave. It's also a requirement before
SplFileInfo::__toString() calls SplFileInfo::getPathname() and

Include stub hash in generated arginfo files

The hash is used to check whether the arginfo file needs to be
regenerated. PHP-Parser will only be downloaded if this is actually
necessary.

This ensures that release artifacts will never try to regenerate
stubs and thus fetch PHP-Parser, as long as you do not modify any
files.

Closes GH-5739.
