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.
