It is better, safer and smaller to let the library routine handle the
strlen(3) call.
Added a note to the documentation suggesting this.

All instances of EVP_*_CTX_gettable_params functions have been renamed
to EVP_*_gettable_ctx_params. Except for the EVP_MD ones which were changed
already.
These functions do not take EVP_*_CTX arguments so their prior naming was
misleading.

Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:
While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.
To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:
#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'
This commit moves the private crypto headers from
'crypto/include/internal' to 'include/crypto'
As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'
hence the superfluous '_int.h' suffixes can be stripped.
The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

It is undefined behaviour to send NULL as either the src, or dest params
in memcpy.
In pkey_kdf.c we had a check to ensure that the src address is non-NULL.
However in some situations it is possible that the dest address could also
be NULL. Specifically in the case where the datalen is 0 and we are using
a newly allocated BUF_MEM.
We add a check of datalen to avoid the undefined behaviour.

BUF_MEM_grow() returns the passed length, but also zero on error. If
the passed length was zero, an extra check to see if a returned zero
was an error or not is needed.

Undo the caching scheme, pass through most controls as parameters, except
for SEED and INFO, where we keep supporting adding data through additional
ctrl calls by collecting the data, and only passing it to the EVP_KDF
before calling its derive function.
