We had the function EVP_CIPHER_CTX_cipher_data which is newly added for
1.1.0. As we now also need an EVP_CIPHER_CTX_set_cipher_data it makes
more sense for the former to be called EVP_CIPHER_CTX_get_cipher_data.

Implement aes128-cbc as a pipeline capable cipher in the dasync engine.
As dasync is just a dummy engine, it actually just performs the parallel
encrypts/decrypts in serial.

Add a flag to indicate that a cipher is capable of performing
"pipelining", i.e. multiple encrypts/decrypts in parallel. Also add some
new ctrls that ciphers will need to implement if they are pipeline capable.

Make PKCS8_PRIV_KEY_INFO opaque. Several accessor functions already exist
for this structure. Two new ones were added to handle attributes.

The old handling of broken formats has been removed and the corresponding
structures simplified.

Also, move all the internal EVP_CIPHER building macros from evp_locl.h

EVP_CIPHER_CTX_flags was returning the flags of its associated
EVP_CIPHER.  However, EVP_CIPHER_CTX has flags of its own, so this
function is quite confusing and therefore error prone.

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).

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.

Looking over names, it seems like we usually use names ending with
_new and _free as object constructors and destructors.  Also, since
EVP_MD_CTX_init is now used to reset a EVP_MD_CTX, it might as well be
named accordingly.
