24554b11f7 gocryptfs-xray: integrate ctlsock path encryption/decryption
Implementation seems to work ok, but is missing tests and
documentation for now.
I will only delete ctlsock-encrypt.bash when both are
done.

c19baa10f8 tests: use t.Name()
We did not use t.Name() as it was not available
before Go 1.8. Now the oldest Go version we support is
Go 1.11, so we can use it.

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.

2568518992 crossbuild.bash: set GOARM=7
From https://github.com/golang/go/wiki/GoArm :

  In cross compilation situations, it is recommended
  that you always set an appropriate GOARM value
  along with GOARCH.

The value seems to default to GOARM=5 if not set
during cross-compilation.

We used to restrict setting xattrs to the "user."
