Linux 5.12 compat: idmapped mounts In Linux 5.12, the filesystem API was modified to support ipmapped mounts by adding a "struct user_namespace *" parameter to a number functions and VFS handlers. This change adds the needed autoconf macros to detect the new interfaces and updates the code appropriately. This change does not add support for idmapped mounts, instead it preserves the existing behavior by passing the initial user namespace where needed. A subsequent commit will be required to add support for idmapped mounted.

This is the same request_mask for statx that's present in the most recent API implemented by zpl_getattr_impl. This commit conditionally adds it to the zpl_generic_fillattr(...) macro, as well as the zfs_getattr_fast(...) implementation, when configure determines it's present in the kernel's generic_fillattr(...).
