Replumbing: Add a mechanism to pre-populate the provider store

OpenSSL will come with a set of well known providers, some of which
need to be accessible from the start.  These are typically built in
providers, or providers that will work as fallbacks.

We do this when creating a new provider store, which means that this
will happen in every library context, regardless of if it's the global
default one, or an explicitely created one.

We keep the data about the known providers we want to make accessible

apps/speed.c: properly address NO_EC2M on systems without SIGALRM

The ecdh_c array is allocated of the same size as ecdh_choices,
whose size depends on whether the support for binary curves is enabled
or not.  (The same goes for ecdsa_c).
On systems without SIGALRM, ecdh_c is indexed by predefined constants
intended for representing the index of the ciphers in the ecdh_choices
array.
However, in case of NO_EC2M some of the #defined constants won't match
and would actually access the ecdh_c out-of-bounds.

Use enum instead of a macro to define the curve indexes so they're

test/params_test.c: Add "real world" parameter testing

test/params_test.c is a program that tries to mimic how a provider and
an application would or could handle OSSL_PARAM arrays.

For the moment, this program tests a very raw way of handling
OSSL_PARAM arrays.  It is, however, written in a way that will
hopefully make it possible to extend with other methods as APIs arise,
and to set up test cases where a "provider" handles the array one way
while the "application" handles it another way.

OSSL_PARAM helper functions.

Provide a number of functions to allow parameters to be set and
retrieved in a type safe manner.  Functions are provided for many
integral types plus double, BIGNUM, UTF8 strings and OCTET strings.

All of the integer functions will widen the parameter data as
required.  This permits a degree of malleability in the parameter
definition.  For example a type can be changed from a thirty two bit
integer to a sixty four bit one without changing application code.
Only four and eight byte integral sizes are supported here.

A pair of real functions are available for doubles.

A pair of functions is available for BIGNUMs.  These accept any sized
unsigned integer input and convert to/from a BIGNUM.

For each OCTET and UTF8 strings, four functions are defined.  This
provide get and set functionality for string and for pointers to
strings.  The latter avoiding copies but have other inherent risks.

Finally, some utility macros and functions are defined to allow
OSSL_PARAM definition arrays to be specified in a simple manner.
There are two macro and one function for most types.  The exception
being BIGNUM, for which there is one macro and one function.

Replumbing: New public API to load or add providers

Adding a provider means creating an internal provier object and adding
it to the store.  This allows the addition of built in providers, be it
in the OpenSSL libraries or in any application.

"Loading" a provider is defined broadly.  A built in provider is already
"loaded" in essence and only needs activating, while a provider in a
dynamically loadable module requires actually loading the module itself.
In this API, "loading" a provider does both.
