[New-bugs-announce] [issue41985] Argument Clinic: add converter for file descriptor

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Local converters for file descriptors which uses PyObject_AsFileDescriptor() are defined and used in several files: Modules/fcntlmodule.c, Modules/posixmodule.c, Modules/selectmodule.c, Modules/termios.c.

The proposed PR replaces them all with a global private function _PyLong_FileDescriptor_Converter() and adds corresponding Argument Clinic converter "fildes".

In future it could be used in more places, allowing to pass a file with fileno() method to functions which accept file descriptor.
