fusefrontend: -sharedstorage: present stable inode numbers
...
Use the Gen field (inode generation) to distinguish hard links
while passing the real inode numbers to userspace.

v2api: -sharestorage: disable hard link tracking & add tests
...
Hard link tracking was not correctly disabled
since the migration to the go-fuse v2 api.
Add a test to ensure it stays off.

inomap: rework logic to efficiently support flags
...
Adding flags allows to use inomap in reverse mode,
replacing the clunky inoBaseDirIV/inoBaseNameFile
logic that causes problems with high underlying
inode numbers ( https://github.com/rfjakob/gocryptfs/issues/457 )
Microbenchmarks (values below) show that the "SingleDev"
case is now much slower due to an extra map lookup,
but this has no visible effects in ./test.bash results,
so there was no time spent optimizing the case further.

inomap will also be used by fusefrontend_reverse
in the future. Split if off openfiletable to make
it independent.
