Jakob Unterwurzacher 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/%

Jakob Unterwurzacher 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/%

Jakob Unterwurzacher 1d2ac1e589 stupidgcm: prefer Go stdlib over OpenSSL on Apple M1

Jakob Unterwurzacher 8f5c2a613d Prefer Go stdlib aes-gcm on arm64 with aes instructions 
We used to prefer openssl in this situation, which
used to make sense, but now Go gained an optimized
assembly implementation for aes-gcm on arm64 with
aes instructions:

Jakob Unterwurzacher d5ce340c02 merge prefer_openssl package into stupidgcm 
Now that I have discovered golang.org/x/sys/cpu and that Go
versions below 1.6 are uncommon, there was not much useful
code left in prefer_openssl.

Merge the remains into stupidgcm.
