69d88505fd go mod: declare module version v2
Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.

All the import paths have been fixed like this:

  find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%

b8d78d6a31 inomap: warn on first use of spillMap
We normally should not need it, warn if we do.
As the tests run with -wpanic, we would catch it.

1bc1db620b fusefrontend: -sharedstorage: present stable inode numbers
Use the Gen field (inode generation) to distinguish hard links
while passing the real inode numbers to userspace.

e2dc52a965 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.

9f9d59ded9 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.

488111ce39 inomap: split into separate package
inomap will also be used by fusefrontend_reverse
in the future. Split if off openfiletable to make
it independent.
