fips: continuous random bit generator tests

For FIPS 140-3 the continuous tests specified in SP 800-90B need to be
included on the output of any entropy source.

They are implemented here as a replacement for the primary DRBG in the FIPS
provider. This results in a setup that looks like this:

+-------------+
| |
| Seed Source |
| |
+------+------+
|
|
v
+-------------+
| |
| CRNG Test |
| |
++----------+-+
| |
| |
v v
+--------------+ +--------------+
| | | |
| Public DRBG | | Private DRBG |
| | | |
+--------------+ +--------------+

An additional benefit, that of avoiding DRBG chains, is also gained.
The current standards do not permit the output of one DRBG to be used
as the input for a second (i.e. a chain).

This also leaves open the future possibility of incorporating a seed
source inside the FIPS boundary.

Cleanups for FIPS options..

The options in fipsprov.c are now generated using macros with fips_indicator_params.inc.
This should keep the naming consistent.

Some FIPS related headers have moved to providers/fips/include so that
they can use fips_indicator_params.inc.
securitycheck.h now includes fipsindicator.h, and fipsindicator.h includes
fipscommon.h.

fipsinstall.c uses OSSL_PROV_PARAM_ for the configurable FIPS options rather than
using OSSL_PROV_FIPS_PARAM_* as this was confusing as to which one should be used.
fips_names.h just uses aliases now for existing public names.

Enable obtaining certain DRBG params without a lock

Even if a DRBG has locking enabled on it, there are certain parameters
which are still safe to obtain even without a lock. The max_request
value is constant for all our DRBGs. The reseed_counter does not matter
if we get it wrong - so it is safe to avoid the lock. So if all we are
reading are those parameters then we take no lock at all.

Refactor the DRBG implementations to manage locking themselves

Previously the EVP layer would call lock and unlock functions on the
underlying DRBG implementation to say when a lock should be acquired and
released. This gives the DRBG implementation no say as to what kind of
lock should obtained (e.g. read/write) or even whether a lock is actually
needed or not.

In reality we know whether a DRBG is supposed to be in locking mode or
not because the "enable_locking()" function will have been called if
locks should be used. Therefore we re-interpret the lock and unlock
functions as "hints" from the EVP layer which we ignore. Instead we
acquire locks only when we need them. By knowing the context we can obtain
either a read or a write lock as appropriate.

This may mean that in some rare cases we acquire the locks more than once
for a single EVP call, if the EVP call makes several calls to the underlying
DRBG. But in practice almost all EVP calls only make one such call.
EVP_RAND_generate() is an example of a call where multiple DRBG calls may
be made. One of these gets the "max_request" parameter (which is constant
for all of our own DRBGs) and it may make several calls to the DRBG generate
call - but only if the requested size is very large which will rarely be
the case.

Segmentation fault in parent rng cleanup

CLA: trivial
When `cleanup_entropy()` is called to cleanup parent by calling
provided `OSSL_FUNC_rand_clear_seed_fn` method, incorrect random
context is passed to the method. So accessing that context creates
a segmentation fault. Parent context should be passed rather than
DRBG's own context.

Stop raising ERR_R_MALLOC_FAILURE in most places

Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called. Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.
