Added X963KDF API

X963 KDF is used for CMS ec keyagree Recipient Info.
The X963 KDF that is used by CMS EC Key Agreement has been moved
into a EVP_KDF object. This KDF is almost identical to the the SSKDF
hash variant, so it has been implemented inside the SSKDF code with
its own method table.

Now that the legacy NID isn't used as a main index for fetched

EVP_FETCH: deal with names without pre-defined NIDs

We didn't deal very well with names that didn't have pre-defined NIDs,

OBJ_bsearch_ and OBJ_bsearch_ex_ are generic functions that don't
really belong with the OBJ API, but should rather be generic utility

Since crypto/stack/stack.c uses OBJ_bsearch_ex_, the stack API ends up

other dependencies.

Therefor, a generic internal function is created, ossl_bsearch().

Allow specifying the tag after AAD in CCM mode

Enforce a strict output length check in CRYPTO_ccm128_tag

Return error if the output tag buffer size doesn't match
the tag size exactly. This prevents the caller from
using that portion of the tag buffer that remains
uninitialized after an otherwise succesfull call to
CRYPTO_ccm128_tag.

Bug found by OSS-Fuzz.

Fix suggested by Kurt Roeckx.

Add a way for the application to get OpenSSL configuration data

OpenSSL_version(OPENSSL_DIR) gives you a nicely formatted string for
display, but if all you really want is the directory itself, you were
forced to parsed the string.

This introduces a new function to get diverse configuration data from
the library, OPENSSL_info().  This works the same way as
OpenSSL_version(), but has its own series of types, currently
including:

OPENSSL_INFO_CONFIG_DIR         returns OPENSSLDIR
OPENSSL_INFO_ENGINES_DIR        returns ENGINESDIR
OPENSSL_INFO_MODULES_DIR        returns MODULESDIR
OPENSSL_INFO_DSO_EXTENSION      returns DSO_EXTENSION

OPENSSL_INFO_DIR_FILENAME_SEPARATOR     returns directory/filename separator
OPENSSL_INFO_LIST_SEPARATOR             returns list separator

For scripting purposes, this also adds the command 'openssl info'.

Configure: make disabling stuff easier and safer

Disabling one thing may mean having to disable other things as well.
We already have a process to auto-disable things through cascading,
but that was under-used.

Making the cascading mechanism available through a function to be
called to disable stuff makes it more automatic, and helps us when we
forget how different disabling options affect others.
