Per SEC 1, the curve coefficients must be padded up to size. See C.2's
definition of Curve, C.1's definition of FieldElement, and 2.3.5's definition
of how to encode the field elements in http://www.secg.org/sec1-v2.pdf.
This comes up for P-521, where b needs a leading zero.

felem_neg does not produce an output within the tight bounds suitable
for felem_contract. This affects build configurations which set
enable-ec_nistp_64_gcc_128.
point_double and point_add, in the non-z*_is_zero cases, tolerate and
fix up the wider bounds, so this only affects point_add calls where the
other point is infinity. Thus it only affects the final addition in
arbitrary-point multiplication, giving the wrong y-coordinate. This is a
no-op for ECDH and ECDSA, which only use the x-coordinate of
arbitrary-point operations.
Note: ecp_nistp521.c has the same issue in that the documented
preconditions are violated by the test case. I have not addressed this
in this PR. ecp_nistp521.c does not immediately produce the wrong
answer; felem_contract there appears to be a bit more tolerant than its
documented preconditions. However, I haven't checked the point_add
property above holds. ecp_nistp521.c should either get this same fix, to
be conservative, or have the bounds analysis and comments reworked for
the wider bounds.

Apart from ssltest_old.c, the test suite relied on e_os.h for the
OSSL_NELEM macro and nothing else.
The ssltest_old.c also requires EXIT and some socket macros.
Create a new header to define the OSSL_NELEM macro and use that instead.

If RAND_add wraps around, XOR with existing. Add test to drbgtest that
does the wrap-around.
Re-order seeding and stop after first success.
Add RAND_poll_ex()
Use the DF and therefore lower RANDOMNESS_NEEDED. Also, for child DRBG's,
mix in the address as the personalization bits.
Centralize the entropy callbacks, from drbg_lib to rand_lib.
(Conceptually, entropy is part of the enclosing application.)
Thanks to Dr. Matthias St Pierre for the suggestion.
Various code cleanups:
-Make state an enum; inline RANDerr calls.
-Add RAND_POLL_RETRIES (thanks Pauli for the idea)
-Remove most RAND_seed calls from rest of library
-Rename DRBG_CTX to RAND_DRBG, etc.
-Move some code from drbg_lib to drbg_rand; drbg_lib is now only the
implementation of NIST DRBG.
-Remove blocklength

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

their error displays. The formatting follows the output format used
on error, except that bignums of sixty four bits or less are displayed
in a more compact one line form.
Added a TEST_note function for producing output without file and line
information.
Update the three tests that call BN_print so they use the new test

We already test in EC_POINT_oct2point that points are on the curve. To
be on the safe side, move this check to
EC_POINT_set_affine_coordinates_* so as to also check point coordinates
received through some other method.
We do not check projective coordinates, though, as
- it's unlikely that applications would be receiving this primarily
internal representation from untrusted sources, and
- it's possible that the projective setters are used in a setting where
performance matters.

The function EC_POINT_is_on_curve does not return a boolean value.
It returns 1 if the point is on the curve, 0 if it is not, and -1
on error. Many usages within OpenSSL were incorrectly using this
function and therefore not correctly handling error conditions.
With thanks to the Open Crypto Audit Project for reporting this issue.

For a local variable:
TYPE *p;
Allocations like this are "risky":
p = OPENSSL_malloc(sizeof(TYPE));
if the type of p changes, and the malloc call isn't updated, you
could get memory corruption. Instead do this:
p = OPENSSL_malloc(sizeof(*p));
Also fixed a few memset() calls that I noticed while doing this.
