936166aff2 Adapt cipher implementations to opaque EVP_CIPHER_CTX
Note: there's a larger number of implementations in crypto/evp/ that
aren't affected because they include evp_locl.h.  They will be handled
in a separate commit.

83b0634702 Add accessors and writers for EVP_CIPHER_CTX
New functions:

- EVP_CIPHER_CTX_encrypting()
- EVP_CIPHER_CTX_iv()
- EVP_CIPHER_CTX_iv_noconst()
- EVP_CIPHER_CTX_original_iv()
- EVP_CIPHER_CTX_buf_noconst()
- EVP_CIPHER_CTX_num()
- EVP_CIPHER_CTX_set_num()
- EVP_CIPHER_CTX_cipher_data()
- EVP_CIPHER_CTX_new_cipher_data()

Note that the accessors / writers for iv, buf and num may go away, as
those rather belong in the implementation's own structure (cipher_data)
when the implementation would affect them (that would be the case when
they are flagged EVP_CIPH_CUSTOM_IV or EVP_CIPH_FLAG_CUSTOM_CIPHER).

8baf9968df Make EVP_CIPHER_CTX opaque and renew the creator / destructor functions
Following the method used for EVP_MD_CTX and HMAC_CTX,
EVP_CIPHER_CTX_init and EVP_CIPHER_CTX_cleanup are joined together
into one function, EVP_CIPHER_CTX_reset, with EVP_CIPHER_CTX_init kept
as an alias.
EVP_CIPHER_CTX_cleanup fills no purpose of its own any more and is
therefore removed.

EVP_MD_CTX_init is now used to reset a EVP_MD_CTX, it might as well be

74cabf3fef Remove EVP_MD_CTX_cleanup and put its functionality into EVP_MD_CTX_init
The idea is that with EVP_MD_CTX_create() and EVP_MD_CTX_destroy(),
EVP_MD_CTX_cleanup and EVP_MD_CTX_init is not used the same as before.
Instead, we need a single function that can be used to reinitialise an
existing EVP_MD_CTX that's been created with EVP_MD_CTX_create()
previously.  Combining EVP_MD_CTX_cleanup and EVP_MD_CTX_init into
that one function is the answer.

fa0c23de83 Adapt HMAC to the EVP_MD_CTX changes
This change required some special treatment, as HMAC is intertwined
with EVP_MD.  For now, all local HMAC_CTX variables MUST be
initialised with HMAC_CTX_EMPTY, or whatever happens to be on the
stack will be mistaken for actual pointers to EVP_MD_CTX.  This will
change as soon as HMAC_CTX becomes opaque.

Also, since HMAC_CTX_init() can fail now, its return type changes from
void to int, and it will return 0 on failure, 1 on success.
