ERR: re-use the err_data field when possible

To deallocate the err_data field and then allocating it again might be
a waste of processing, but may also be a source of errors when memory
is scarce.  While we normally tolerate that, the ERR sub-system is an
exception and we need to pay closer attention to how we handle memory.

This adds a new err_data flag, ERR_TXT_IGNORE, which means that even
if there is err_data memory allocated, its contents should be ignored.

test/evp_test.c: modify to use OSSL_PROVIDER_available()

This changes the stanza format used so far.  Some test stanza had the
following line, only possible for digests:

    Legacy = 1

These have been traded for the following:

    Availablein = legacy

That line is globally available in all test stanza and can be used to

provider needs to match, so one might have something like this for

    Availablein = default fips

This means that one of those providers must be available for the test
stanza to be performed.

If the providers mentioned for a stanza aren't available, the test is

If this line isn't used in a stanza, the algorithm is assumed to be

Add basic EVP_KEYMGMT API and libcrypto <-> provider interface

The idea with the key management "operation" is to support the
following set of functionality:

- Key domain parameter generation
- Key domain parameter import
- Key domain parameter export

- Key generation
- Key import
- Key export
- Key loading (HSM / hidden key support)

With that set of function, we can support handling domain parameters
on one provider, key handling on another, and key usage on a third,
with transparent export / import of applicable data.  Of course, if a
provider doesn't offer export / import functionality, then all
operations surrounding a key must be performed with the same
provider.

This method also avoids having to do anything special with legacy
assignment of libcrypto key structures, i.e. EVP_PKEY_assign_RSA().
They will simply be used as keys to be exported from whenever they are
used with provider based operations.

This change only adds the EVP_KEYMGMT API and the libcrypto <->

Fix init_get_thread_local()

Previously, init_get_thread_local() pushed the thread event handler
list onto the global register before calling CRYPTO_THREAD_set_local(),
and when the latter failed, forgot to pop the list from the stack again.

Instead of cleaning the stack on error, this commit avoids the situation
entirely by postponing the push operation until all other operations
succeeded. This reordering also significantly reduces the scope of the
critical section.

Another simplification of the code is achieved by moving the push operation
onto the register (which is disabled in FIPS mode) into a separate function.
