Remove assert_options() return value info

The ASSERT_CALLBACK value is not validated at all -- it's possible
to set it to an arbitrary value. As such, the function can also
return any value or type (even without outright abuse, the opcache
func info was wrong in that the return can be rcn, and the array
can be array_of_ref).

Accept null for microseconds argument in stream_select() (#6879)

The deprecation of passing null is thrown otherwise.

If the timeout is calculated conditionally before calling stream_select(), passing to avoid the deprecation seems unreasonable, example:

https://github.com/amphp/amp/blob/7d4bbc6e0b47c6bb39b6cce1a4b5942e0c5125fb/lib/Loop/NativeDriver.php#L286

Also enforce that if $seconds is null, then $microseconds should be null as well. However 0 is still accepted (with deprecation) for backwards compatibility.

Add fsync() and fdatasync() functions

fsync is a straightforward wrapper around the same C function
(implemented on Windows API as _commit() with identical signature).

From the man pages:

fsync() transfers ("flushes") all modified in-core data of (i.e.,
modified buffer cache pages for) the file referred to by the file
descriptor fd to the disk device (or other permanent storage
device) so that all changed information can be retrieved even if
the system crashes or is rebooted. This includes writing through
or flushing a disk cache if present. The call blocks until the
device reports that the transfer has completed.

Remove the "getdir" function which was introduced accidentally

The actual name of this function is dir(), but ever since it was
introduced in PHP 3, its internal name was "getdir", leading to it
being mistaken for an alias. This went unnoticed until the switch
to stubs for generating arginfo, at which point getdir() became a
real but undocumented function.

Fixes bug #80914.

Closes GH-6855.

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.
