        src/sys/fs/tmpfs: tmpfs.h tmpfs_subr.c tmpfs_vnops.c

Log Message:
Truncate directory cookies to 31 bits to avoid problems exposed in Linux
binaries which cast the returned values to 64-bits and fail due to sign
expansion.  More details are provided in the big comment in tmpfs.h that
describes how the new tmpfs_dircookie works.

This is a rather ugly hack that shall be fixed with a cleaner solution,
but this resolves the problem in an effective way.

Fixes kern PR/32034.
