Raw private/public key loading may fail for X25519/X448 if ec has been
disabled.

Also fixed a missing blank line in evppkey.txt resulting in a warning in

Previously private and public keys had to be pem encoded to be read by
evp_test. This enables us to embed the raw private/public key values
in the test file. The algorithm has to support EVP_PKEY_new_private_key()
and EVP_PKEY_new_public_key() for this to work.

that needed test_main now works using the same infrastructure as tests that used
register_tests.

This meant:
* renaming register_tests to setup_tests and giving it a success/failure return.
* renaming the init_test function to setup_test_framework.
* renaming the finish_test function to pulldown_test_framework.
* adding a user provided global_init function that runs before the test frame
    work is initialised.  It returns a failure indication that stops the stest.
* adding helper functions that permit tests to access their command line args.
* spliting the BIO initialisation and finalisation out from the test setup and
    teardown.
* hiding some of the now test internal functions.
* fix the comments in testutil.h

Allow multiple "Input" lines to call the update function multiple times.
Add "Ncopy" keyword to copy the input buffer. So for example:

Input = "a"
Ncopy = 1024

Will create a buffer consisting of 1024 "a" characters.

If EC support is enabled we should catch also EC_R_UNKNOWN_GROUP as an hint to
an unsupported algorithm/curve (e.g. if binary EC support is disabled).

Before this commit the issue arise for example if binary EC keys are added in
evptests.txt, and the test is run when EC is enabled but EC2m is disabled.

E.g. adding these lines to evptests.txt would reproduce the issue:

The documentation of this function states that the password parameter
can be NULL. However, the implementation returns an error in this case
due to the inner workings of the HMAC_Init_ex() function.
With this change, NULL password will be treated as an empty string and
PKCS5_PBKDF2_HMAC() no longer fails on this input.

I have also added two new test cases that tests the handling of the
special values NULL and -1 of the password and passlen parameters,
respectively.

The core SipHash supports either 8 or 16-byte output and a configurable
number of rounds.
The default behavior, as added to EVP, is to use 16-byte output and
2,4 rounds, which matches the behavior of most implementations.
There is an EVP_PKEY_CTRL that can control the output size.
