When an `PHP_OUTPUT_HANDLER_FAILURE` occurs, the output handler becomes
disabled (i.e. the `PHP_OUTPUT_HANDLER_DISABLED` flag is set). However,
there is no guard for disabled handlers in `php_output_handler_op()`
what may cause serious issues (as reported, UB due to passing `NULL` as
the 2nd argument of `memcpy`, because the handler's buffer has already
been `NULL`ed). Therefore, we add a respective guard for disabled
handlers, and return `PHP_OUTPUT_HANDLER_FAILURE` right away.
Closes GH-15183.
The 'rl_pending_input' is a variable in Readline library and checking it
with PHP_CHECK_LIBRARY wouldn't find it on some systems.
Library check works on most systems but not on the mentioned AIX in the
bug as it exports variables and functions differently whereas the linker
couldn't resolve the variable as a function.
This should fix the build on systems where this caused issues, such as
AIX.
The <readline/readline.h> is not self-contained header and needs to also
have <stdio.h> included before to have FILE type available. This fixes
the issue on unpatched default readline installations, such as macOS.
Checking this variable ensures that the found library is the correct
library and also that it is of minimum version needed by current PHP
code (https://bugs.php.net/48608).
The library check:
```c
| char rl_pending_input ();
| int main (void) {
| return rl_pending_input ();
| }
```
The declaration check:
```c
| #include <stdio.h>
| #include <readline/readline.h>
| int main (void) {
| #ifndef rl_pending_input
| #ifdef __cplusplus
| (void) rl_pending_input;
| #else
| (void) rl_pending_input;
| #endif
| #endif
| ;
| return 0;
| }
```

When cloning a document, doc will not be equal to the actual new
document clone->doc. clone->doc will always point to the correct
document so use that instead when comparing document nodes.

These get the next and previous sibling nodes, respectively.
We can already kind of do this by using the $child array, but that's
inconvenient when actually walking the tree by only using node
instances. Since the class is final, there is no BC break here.
Closes GH-15047.
Using compound literals is conforming to C99 (and up), but not with any
C++ standard. Since the code is in a public header, it might be used
by C++ extensions. Unfortunately, we cannot even used designated
initializers, because these are a C++20 feature, so we stick with
classic C/C++ code.
Closes GH-15100.
Instead of fixing up temporaries count in between observer steps, just apply the additional temporary in the two affected observer steps.
Closes GH-14018.
For top-level anonymous type definition we never store the declaration anywhere
else nor the type anywhere else.
The declaration keeps owning the type and it goes out of scope.
For anonymous fields this gets handled by the add_anonymous_field code that
removes the type from the declaration.
This patch does something similar in the parsing code when it is
detected we're dealing with an anonymous enum in a top-level declaration.
Closes GH-14839.
