Jonathan Nieder 0ed8d8da37 doc hash-function-transition: pick SHA-256 as NewHash 
From a security perspective, it seems that SHA-256, BLAKE2, SHA3-256,
K12, and so on are all believed to have similar security properties.
All are good options from a security point of view.

SHA-256 has a number of advantages:

* It has been around for a while, is widely used, and is supported by
  just about every single crypto library (OpenSSL, mbedTLS, CryptoNG,
  SecureTransport, etc).

* When you compare against SHA1DC, most vectorized SHA-256
  implementations are indeed faster, even without acceleration.

* If we're doing signatures with OpenPGP (or even, I suppose, CMS),
  we're going to be using SHA-2, so it doesn't make sense to have our
  security depend on two separate algorithms when either one of them
  alone could break the security when we could just depend on one.

So SHA-256 it is.  Update the hash-function-transition design doc to
say so.

After this patch, there are no remaining instances of the string
"NewHash", except for an unrelated use from 2008 as a variable name in
t/t9700/test.pl.
