build options.

All fispcanisterbuild builds only build fipscanister.o and include symbol
renaming.

Move all renamed symbols to fipssyms.h

Update README.FIPS

Update/fix prototypes in fips.h

FIPS capable: i.e. FIPS module is supplied externally.

New function to lookup digests by NID in module.

Minor optimisation: if supplied hash is NULL to FIPS RSA functions and
we are using PKCS padding get digest NID from otherwise unused saltlen
parameter instead.

Fix crash if callback not set.

allow status of POST to be monitored and/or failures induced.

NULL. Always allocate signature buffer.

Update ECDSA selftest to use fips_pkey_signature_test. Add copyright notice
to file.

Rebuild all FIPS error codes to clean out old obsolete codes.

Set FIPS RAND_METHOD at same time as OpenSSL RAND_METHOD.

now use an internal RAND_METHOD. All dependencies to OpenSSL standard
PRNG are now removed: it is the applications resposibility to setup
the FIPS PRNG and initalise it.

Initial OpenSSL RAND_init_fips() function that will setup the DRBG
