584ac22110 Make ecdsatest work with nonces.
Update ecdsatest to use ECDSA_sign_setup and ECDSA_sign_ex, this
avoids the nonce generation which would otherwise break the test.

Reinstate ecdsatest.

8d6a75dc3a Avoid need to change function code.
Keep original function names for nonce versions so we don't have to change
error function codes.

190c615d43 Make `safe' (EC)DSA nonces the default.
This change updates 8a99cb29 to make the generation of (EC)DSA nonces
using the message digest the default. It also reverts the changes to
(EC)DSA_METHOD structure.

In addition to making it the default, removing the flag from EC_KEY
means that FIPS modules will no longer have an ABI mismatch.

8a99cb29d1 Add secure DSA nonce flag.
This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

4c3296960d Remove the dual-callback scheme for numeric and pointer thread IDs,
deprecate the original (numeric-only) scheme, and replace with the
CRYPTO_THREADID object. This hides the platform-specifics and should reduce
the possibility for programming errors (where failing to explicitly check
both thread ID forms could create subtle, platform-specific bugs).

Thanks to Bodo, for invaluable review and feedback.

f7ccba3edf There was a need to support thread ID types that couldn't be reliably cast
to 'unsigned long' (ie. odd platforms/compilers), so a pointer-typed
version was added but it required portable code to check *both* modes to
determine equality. This commit maintains the availability of both thread
ID types, but deprecates the type-specific accessor APIs that invoke the
callbacks - instead a single type-independent API is used.  This simplifies
software that calls into this interface, and should also make it less
error-prone - as forgetting to call and compare *both* thread ID accessors
could have led to hard-to-debug/infrequent bugs (that might only affect
certain platforms or thread implementations). As the CHANGES note says,
there were corresponding deprecations and replacements in the
thread-related functions for BN_BLINDING and ERR too.

- hide the EC_KEY structure definition in ec_lcl.c + add
  some functions to use/access the EC_KEY fields
- change the way how method specific data (ecdsa/ecdh) is
  attached to a EC_KEY
- add ECDSA_sign_ex and ECDSA_do_sign_ex functions with
  additional parameters for pre-computed values
- rebuild libeay.num from 0.9.7
