OPENSSL_FIPSCANISTER is only set if the fips module is being built
(as opposed to being used). Since the fips module wont be built in
master this is redundant.

Facilitate switch to custom scatter-gather routines. This modification
does not change algorithms, only makes it possible to implement
alternative. This is achieved by a) moving precompute table to assembly
(perlasm parses ecp_nistz256_table.c and is free to rearrange data to
match gathering algorithm); b) adhering to explicit scatter subroutine
(which for now is simply a memcpy). First implementations that will use
this option are 32-bit assembly implementations, ARMv4 and x86, where
equivalent of current read-whole-table-select-single-value algorithm
is too time-consuming. [On side note, switching to scatter-gather on
x86_64 would allow to improve server-side ECDSA performance by ~5%].

This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

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.
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.

Additional changes:
- use EC_GROUP_get_degree() in apps/req.c
- add ECDSA and ECDH to apps/speed.c
- adds support for EC curves over binary fields to ECDSA
- new function EC_KEY_up_ref() in crypto/ec/ec_key.c
- reorganize crypto/ecdsa/ecdsatest.c
- add engine support for ECDH
- fix a few bugs in ECDSA engine support

CRYPTO_set_mem_debug_options() instead of CRYPTO_dbg_set_options(),
which is the default implementation of the former and should usually
not be directly used by applications (at least if we assume that the
options accepted by the default implementation will also be meaningful
to any other implementations).
Also fix apps/openssl.c and ssl/ssltest such that environment variable
setting 'OPENSSL_DEBUG_MEMORY=off' actively disables the compiled-in
library defaults (i.e. such that CRYPTO_MDEBUG is ignored in this
case).
In err.c, flags int_error_hash_set and int_thread_hash_set
appear superfluous since we can just as well initialize
int_error_hash and int_thread_hash to NULL.
Change some of the err.c formatting to conform with the rest of
OpenSSL.
