6342b6e332 Redirection of ECDSA, ECDH operations to FIPS module. 
Also use FIPS EC methods unconditionally for now: might want to use them
only in FIPS mode or with a switch later.

69e2ec63c5 Reorganise ECC code so it can use FIPS module. 
Move compression, point2oct and oct2point functions into separate files.

Add a flags field to EC_METHOD.

Add a flag EC_FLAGS_DEFAULT_OCT to use the default compession and oct functions
(all existing methods do this). This removes dependencies from EC_METHOD while
keeping original functionality.

Backport from HEAD with minor changes.

e24b01cc6f Have EC_NISTP224_64_GCC_128 treated like any algorithm, and have disabled by

945ba0300d Add call to ENGINE_register_all_complete() to ENGINE_load_builtin_engines(), 
this means that some implementations will be used automatically, e.g. aesni,
we do this for cryptodev anyway.

Setup cpuid in ENGINE_load_builtin_engines() too as some ENGINEs use it.

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.
