Richard Levitte e2f5df3613 PROV: Add OIDs we know to all provider applicable algorithms
The OIDs were extracted with the help of libcrypto's ASN1 OID database.

While doing this, we move all the names strings to macro definitions,
to avoid duplication and conflicting names declarations.  Those macros
are all in providers/implementations/include/prov/names.h
