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).
See https://golang.org/design/draft-gobuild

Tamir Duberstein be400aefbc all: build tags: appengine,!gccgo => purego,gc 
appengine is obsolete and superseded by purego, and gc is a more
precise tag for files that use gc-syntax assembly.

Michael Munday 5d647ca157 sha3: fix SHA-3 on s390x when using KIMD instruction 
An illegal instruction would occur due to a bug in the way input
slices were rounded down in size to a multiple of the rate for a
given hash type. This would only occur when the Write function
was called with more than ~3KiB of data and the length of the data
was not a multiple of the rate.

Fixes golang/go#36459.

Michael Munday e37aea1ec3 sha3: use x/sys/cpu for s390x feature detection 
Use the recently added CPU feature detection API rather than custom
assembly.

While we are here also make vet happy by renaming params in the asm
file to chain to match the go function declaration.
