This is an interface between Core dispatch table fetching and
EVP_{method}_fetch(). All that's needed from the diverse method
fetchers are the functions to create a method structure from a
dispatch table, a function that ups the method reference counter and a
function to free the method (in case of failure).
This routine is internal to the EVP API andis therefore only made
accessible within crypto/evp, by including evp_locl.h

Changed PKEY/KDF API to call the new API.
Added wrappers for PKCS5_PBKDF2_HMAC() and EVP_PBE_scrypt() to call the new EVP KDF APIs.

We currently implement EVP MAC methods as EVP_PKEY methods. This
change creates a separate EVP API for MACs, to replace the current
EVP_PKEY ones.
A note about this EVP API and how it interfaces with underlying MAC
implementations:
Other EVP APIs pass the EVP API context down to implementations, and
it can be observed that the implementations use the pointer to their
own private data almost exclusively. The EVP_MAC API deviates from
that pattern by passing the pointer to the implementation's private
data directly, and thereby deny the implementations access to the
EVP_MAC context structure. This change is made to provide a clearer
separation between the EVP library itself and the implementations of
its supported algorithm classes.

Previously they were using EVP_EncodeBlock/EVP_DecodeBlock. These are low
level functions that do not handle padding characters. This was causing
the SRP code to fail. One side effect of using EVP_EncodeUpdate is that
it inserts newlines which is not what we need in SRP so we add a flag to
avoid that.

Since the public and private DRBG are per thread we don't need one
per ssl object anymore. It could also try to get entropy from a DRBG
that's really from an other thread because the SSL object moved to an
other thread.

When doing in place encryption the overlapping buffer check can fail
incorrectly where we have done a partial block "Update" operation. This
fixes things to take account of any pending partial blocks.

This was done by the following
find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
print unless $. == 1 && m@/\* .*\.[ch] \*/@;
close ARGV if eof; # Close file to reset $.
And then some hand-editing of other files.

We follow the method used for EVP_MD.
Also, move all the internal EVP_CIPHER building macros from evp_locl.h
to evp_int.h. This will benefit our builtin EVP_CIPHERs.

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.
