Used in gocryptfs-xray, and will also be used in -info.

When somebody posts "gocryptfs -speed" results, they are
most helpful together with the CPU model. Add the cpu model
to the output.
Example:
$ ./gocryptfs -speed
gocryptfs v2.2.0-beta1-5-g52b0444-dirty; go-fuse v2.1.1-0.20210825171523-3ab5d95a30ae; 2021-09-14 go1.17.1 linux/amd64
cpu: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz; with AES acceleration
AES-GCM-256-OpenSSL 862.79 MB/s
AES-GCM-256-Go 997.71 MB/s (selected in auto mode)
AES-SIV-512-Go 159.58 MB/s
XChaCha20-Poly1305-OpenSSL 729.65 MB/s
XChaCha20-Poly1305-Go 843.97 MB/s (selected in auto mode)
|

|
The rewritten openssl backend does not support this flag anymore,
and it was inherently dangerour. Drop it (ignored for compatibility)
|
|
|
|
Add PreferOpenSSLXchacha20poly1305,
rename PreferOpenSSL -> PreferOpenSSLAES256GCM.
|
|
New() -> NewAES256GCM()
Also add missing NewChacha20poly1305
constructor in without_openssl.go.

The bEncrypt helper massively deduplicates the code,
and reusing the dst buffer gives higher performance,
and that's what gocryptfs does in normal operation via
sync.Pool.

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/%

This is unclear to users, as seen on

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.

Force decode of encrypted files even if the integrity check fails, instead of
failing with an IO error. Warning messages are still printed to syslog if corrupted
files are encountered.
It can be useful to recover files from disks with bad sectors or other corrupted
media.
Closes https://github.com/rfjakob/gocryptfs/pull/102 .

Yields a nice reduction in code size.

Old Go versions miss cipher.NewGCMWithNonceSize, which causes:
internal/speed/speed.go:95: undefined: cipher.NewGCMWithNonceSize

A crypto benchmark mode like "openssl speed".
