Sebastiaan van Stijn b8ffc16e10 blake2b: drop Go 1.6, Go 1.8 compatibility 
Other packages already dropped compatibility with go < 1.12, so it
should be safe to remove it for this package as well.

go fix ./...

Using go1.21.3.

Also update avo to v0.5.0 in the curve25519/internal/field/_asm module.
It's newer and produces no diff in the generated code.

For golang/go#60268.

Russ Cox 5ea612d1eb all: go fmt ./... 
Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).

Not strictly necessary but will avoid spurious changes
as files are edited.

Part of //go:build change (#41184).

Tobias Klauser d6449816ce blake2b: use internal/cpu to determine AVX and SSE 4 support 
CL 106235 removed runtime.support_avx on which blake2b depends to
determine AVX support. Switch to use the corresponding feature flags
from internal/cpu instead. While at it, also use AVX2 and SSE4 (for Go
1.7 and later) from there.
