Remove bool return type from assert_options

Not seeing any way this function can return bool.

Add missing image_type_to_extension() argument

Fix #79805: sapi_windows_vt100_support throws TypeError

It does not make sense to throw a `TypeError` when the stream can't be
analyzed. If `sapi_windows_vt100_support()` is used as getter, we just
return `false` in that case; if the function is used as setter, we
additionally trigger a warning.

We also fix the test cases for this function, which have been broken
before. Note that these tests are still whitespace sensitive.

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.

Fix the default parameter values of stream_socket_client()

Mark $time argument of touch() as UNKNOWN as well

For some reason I thought that passing 0 is same as current time,
but that's not the case.

Mark fgets() argument as UNKNOWN

If no value is passed, this reads as much as necessary, not 1024
bytes.

Change parameter default to always available value

`SIGTERM` is only defined in ext/pcntl, and as such never available on
Windows. Moving the constant to ext/standard does not make much sense,
because that parameter is actually unused on Windows. Therefore, we
use the magic number `15` instead, what is also done in the PHP manual.

The actual default here is $time, not 0.

Mark rand/mt_rand args as UNKNOWN

The second argument should be mt_getrandmax(), not PHP_INT_MAX.
Additionally this function only accepts either zero or two arguments,
so err on the side of being conservative and mark both UNKNOWN.

Mark array_walk $userdata arg as UNKNOWN

It makes a difference whether this arg is not passed or is null.
