EVP_PKEY_CTX_set_data(3) and EVP_PKEY_CTX_get_data(3) that we still

EVP_PKEY_CTX_set_app_data(3) and EVP_PKEY_CTX_get_app_data(3).

EVP_EncryptInit(3) is among the most important "how to drive" manuals,
but it is still excessively long and complicated. To reduce the amount
of distractions a bit, split out three deprecated functions into a new
manual page EVP_CIPHER_CTX_init(3). No text change.

In part suggested by tb@, who agrees with the direction.

Split three new manual pages EVP_CIPHER_nid(3), EVP_CIPHER_CTX_ctrl(3),
and EVP_CIPHER_CTX_set_flags(3) out of the excessively large and
unwieldy EVP_EncryptInit(3). This causes a number of inaccuracies
and gaps to stand out, but i'm not mixing text changes or content
additions into this split.

Using very useful feedback from tb@ regarding what belongs together
and how important the various functions are. I refrained from bothering
him with the complete patch, but he likes the general direction.

Document EVP_{CIPHER,MD}_do_all{,_sorted}(3)

The function prototypes in the SYNOPSIS don't look great, but schwarze
assures me that this is how it is supposed to be. It is rather strange
that OpenSSL chose to sprinkle OPENSSL_init_crypto() calls into these
four functions rather than two inside OBJ_NAME_do_all{,_sorted}(3).
Surely there was a good reason for that.
