Unifdef OPENSSL_NO_ENGINE in libcrypto regress

Let ecdsatest exercise ECParameters_dup() a bit

This currently leaks, which will fixed in a follow-on commit.

making ECDSA signatures deterministic. This was gutted a long time ago
and the function should have followed its wrappers into the attic.

Simplify and clean up the ecdsa test a little. Use stdio instead of BIO
for output, use 'err' as a label and avoid some silly repetitions.

Some missing return checks

Avoid some buffer overflows in ecdsatest

The ASN.1 encoding of the modified ECDSA signature can grow in size due to
padding of the ASN.1 integers. Instead of reusing the same signature buffer

Check EVPDigest* return values.

CID 351293

Rework ecdsatest to build after the bump and link statically for now

ecdsatest: make this test compile with opaque EVP_MD_CTX.

some more style fixes

This code is already painful enough to look at. Putting the braces at the
right spot helps this a bit. Other whitespace and typo fixes while there.

Use arc4random_buf() instead of RAND_bytes() or RAND_pseudo_bytes() (most
with unchecked return values).

remove OPENSSL_malloc and CRYPTO_malloc goo from the regress tests.
ok miod@ jsing@ guenther@

ECDSA signature computation involves a random number. Remove the test trying to
force what RAND_bytes() will return and comparing it against known values -
I can't let you do this, Dave.

Import the OpenSSL libcrypto tests in a form suitable for our rergress
infrastructure.
The following tests have not been imported, for their code lacks a licence:
asn1, rsa, sha256, sha512, wp.
