Move ECC and FFDH macros to internal header

Browse Source 
ECC macros used in the following files:

library/pk.c
library/pk_wrap.c
library/pkparse.c
library/pkwrite.c
library/ssl_misc.h
library/ssl_tls12_client.c

FFDH macro use only in library/ssl_misc.h so could possibly be moved
there, but it seems cleaner to keep it close to the ECC macros are they
are very similar in nature.
