Subject: Weed out the last remaining refences to the obsolete function
 EVP_MD_CTX_init(3) and talk about EVP_MD_CTX_new(3) instead. This is similar
 in spirit to OpenSSL commit 25191fff (Dec 1, 2015), but  i'm also mentioning
 EVP_MD_CTX_reset(3), slightly reordering some sentences in a more systematic
 way, and improving some related wordings to be more precise and read better.
