Create replacement header files inside openbsd-compat for common headers
that are missing on a given platform. Usually these are just empty,
but in some cases they'll include the equivalent file. This avoids
having to wrap those includes in '#ifdef HAVE_FOO_H' and reduces the
diff vs OpenBSD.
If we create any such headers, add the path to includes.
Initially just stdint.h, more to follow.

ML-KEM768 with ECDH/X25519 from the Internet-draft:
https://datatracker.ietf.org/doc/html/draft-kampanakis-curdle-ssh-pq-ke-03
This is based on previous patches from markus@ but adapted to use the
final FIPS203 standard ML-KEM using a formally-verified implementation
from libcrux.
Note this key exchange method is still a draft and thus subject to
change. It is therefore disabled by default; set MLKEM=yes to build it.
We're making it available now to make it easy for other SSH
implementations to test against it.

(20221122) and change the import approach to the same one we use for
Streamlined NTRUPrime: use a shell script to extract the bits we need from
SUPERCOP, make some minor adjustments and squish them all into a single file.

- remove unneeded header files and typedefs and rely on crypto_api.h - add
defines to map types used to the crypto_api ones instead of typedefs. This
prevents typedef name collisions in -portable. - remove CRYPTO_NAMESPACE
entirely instead of making it a no-op - delete unused functions and make the
remaining ones that aren't exported static.

exchange method based on Streamlined NTRU Prime (coupled with X25519).
The previous [email protected] method is
replaced with [email protected]. Per the authors,
sntrup4591761 was replaced almost two years ago by sntrup761.
The sntrup761 implementaion, like sntrup4591761 before it, is public
domain code extracted from the SUPERCOP cryptography benchmark
suite (https://bench.cr.yp.to/supercop.html).
Thanks for Daniel J Bernstein for guidance on algorithm selection.
Patch from Tobias Heider; feedback & ok markus@ and myself
(note this both the updated method and the one that it replaced are
disabled by default)

Replace ED25519's private SHA-512 implementation with a
call to the regular digest code. This speeds up compilation considerably. ok
