Add `F_DUPFD_QUERY` to `fcntl`

[rruuaanng]

Feature or enhancement

Proposal:

It's used to query and copy a target file descriptor. for example:

import fcntl

f = /* open a file */;
/* 'ret' must be greater equal than 5 */
ret = fcntl.fcntl(fd, F_DUPFD_QUERY, 5);

Has this already been discussed elsewhere?
