Fixes#6277
Description:
Make each of the five EdDSA instances defined in RFC 8032 -- Ed25519,
Ed25519ctx, Ed25519ph, Ed448, Ed448ph -- available via the EVP APIs.
The desired EdDSA instance is specified via an OSSL_PARAM.
All instances, except for Ed25519, allow context strings as input.
Context strings are passed via an OSSL_PARAM. For Ed25519ctx, the
context string must be nonempty.
Ed25519, Ed25519ctx, Ed448 are PureEdDSA instances, which means that
the full message (not a digest) must be passed to sign and verify
operations.
Ed25519ph, Ed448ph are HashEdDSA instances, which means that the input
message is hashed before sign and verify.
Testing:
All 21 test vectors from RFC 8032 have been added to evppkey_ecx.txt
(thanks to Shane Lontis for showing how to do that). Those 21 test
vectors are exercised by evp_test.c and cover all five instances.

This is not a big problem for higher level keygen, as these set e

A zero BIGNUM contains zero bytes, while OSSL_PARAMs with an INTEGER (or

If an error occurs during a flush on a BIO_f_cipher() then in some cases
we could get into an infinite loop. We add a check to make sure we are
making progress during flush and exit if not.
This issue was reported by Octavio Galland who also demonstrated an
infinite loop in CMS encryption as a result of this bug.
The security team has assessed this issue as not a CVE. This occurs on
*encryption* only which is typically processing trusted data. We are not
aware of a way to trigger this with untrusted data.
