Subject: [PATCH] crypto/hmac: Deprecate hmac.NewMD5, hmac.NewSHA1 and
 hmac.NewSHA256

Remove NewMD5, NewSHA1 and NewSHA256 in favor of using New and
explicitly importing the used hash-function. This way when using, for
example, HMAC with RIPEMD there's no md5, sha1 and sha256 linked in
through the hmac package.

A gofix rule is included, and applied to the standard library (3 files
altered).

This change is the result of a discussion at
https://golang.org/cl/5550043/ to pull the discussion about
deprecating these functions out of that issue.
