(EC)DSA signature fix (#670)
* Write a test - signatures with EC keys (#609)
* Ask for signature length before allocating a buffer.
This fixes a potential heap buffer overflow that may happen when a signature
is longer than the private key, as with X9.62 ECDSA (#609).
* change approach to EVP_PKEY_size and add changelog
* add a small assert
