dtucker@openbsd.org 599df78f30 upstream: Update the sntrup761 creation script and generated code:
- 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.

dtucker@openbsd.org 91bac5e95b upstream: estructure sntrup761.sh to process all files in a single
list, which will make it easier to reorder.  Re-inline int32_MINMAX.  ok

djm@openbsd.org 2c71cec020 upstream: Update/replace the experimental post-quantim hybrid key
exchange method based on Streamlined NTRU Prime (coupled with X25519).

The previous sntrup4591761x25519-sha512@tinyssh.org method is
replaced with sntrup761x25519-sha512@openssh.com. 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)
