Add support for the "fips140" mode of Go: - https://go.dev/doc/security/fips140 - https://csrc.nist.gov/projects/cryptographic-module-validation-program/certificate/5247 You can build with `make fips140`, see the README changes for more info. Some differences from the boringcrypto builds: - We switch to using `go:linkname crypto/tls.aeadAESGCMTLS13`, which gives us the fips implementation for both `boringcrypto` and `fips140` modes. This means we also no longer need `-checklinkname=0` - Go native `fips140` doesn't need CGO_ENABLED=1 - We decide if we should use the fips140 GCM at runtime, if `fips140.Enabled()` is true. If you use the `make release-fips140`, we build with build tag `fips140enforce` which ensures the binary is running with fips140 enabled and that only P256 / AES-GCM is being used. If you don't want this enforce mode, you can build without the build tag.
