atomic FD_CLOEXEC support

Description

​Many POSIX calls have variants to support atomic setting of CLOEXEC, to avoid race conditions when setting after the FDs have been created.

Some apps require some, others work better when they are present.

NBDKit will require some.

We also might want to support O_CLOEXEC (even by default ?) on queries btw.
