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.

Allow all scalar types in ini_set()

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.

Closes GH-6680.

Don't return null from password_get_info()

The get_info() handler should never fail, but even if it does,
we should still return a proper info array -- it doesn't make
sense that a completely incorrect hash returns an info array,
but a hash that is recognized but for which the options can't
be extracted would return null.

Rebased and modified version of #4886

- Use .stub.php files
- Add opcache constant evaluation when argument is a constant
- Change from is_list(mixed $value) to array_is_list(array $array)

gen_stub: Don't use $aliasMap during verification

Some functions have multiple aliases, while the $aliasMap can

Methodsynopsis generation probably shouldn't use it either, but
at least that case seems to only be interested in whether there
is an alias at all.

Normalize substr() behavior

Make the behavior of substr(), mb_substr(), iconv_substr() and
grapheme_substr() consistent when it comes to the handling of
out of bounds offsets. substr() will now always clamp out of
bounds offsets to the string boundary. Cases that previously
returned false will now return an empty string. This means that
substr() itself *always* returns a string now (like mb_substr()
already did before.)
