34d8a498c4 Unbreak hyperlinks broken by go mod v2 conversion 
Commit

  69d88505fd go mod: declare module version v2

translated all instances of "github.com/rfjakob/gocryptfs/" to
"github.com/rfjakob/gocryptfs/v2/".

Unfortunately, this included hyperlinks.

Unbreak the hyperlinks like this:

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

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/%

17f859d3c4 fusefronted: report plaintext size on symlink creation 
gocryptfs 2.0 introduced the regression that the size
reported at symlink creation was the ciphertext size,
which is wrong.

Report the plaintext size.

1fb18f4a9e tests: filter leaked fds by prefix 
When running

in isolation, it failed like this:

  fd leak? before, after:

  [0r=/dev/null 3w=/dev/null 5w=/tmp/go-build366655199/b001/testlog.txt 7r=/proc/8078/fd (hidden:4)]
