Maintain EVP_MD_CTX invariants. Thanks to Lennart Beringer for pointing that that malloc failures could lead to invalid EVP_MD_CTX states. This change cleans up the code in general so that fallible operations are all performed before mutating objects. Thus failures should leave objects in a valid state. Also, |ctx_size| is never zero and a hash with no context is not sensible, so stop handling that case and simply assert that it doesn't occur.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
