Rename the C based AES implementation to *_generic() and provide
*_internal() wrappers for these. This allows for architectures to provide
accelerated versions without having to also provide a fallback
implementation.

Move opensslconf.h to a machine-independent place2025-08-25T16:48:02+00:00tb2025-08-25T16:48:02+00:00urn:sha1:6cbc8c56cfb66d812e5b9f335973b11b213f5665
After drilling through many layers of fossilized turds from a
long-forgotten millenium, jsing and I finally found oil^Wa
machine-independent version of opensslconf.h.
Remove the no longer needed versions in arch/*/ and move one copy
to the top level. Add an RCS tag and place the remaining garbage
in the public domain.

Hook additional s2n-bignum routines to the amd64 build.2025-08-14T15:12:53+00:00jsing2025-08-14T15:12:53+00:00urn:sha1:07bac2b524750c4dfd196516fe31b97d149acde4Add CPU feature detection for ADX on amd64.2025-08-14T15:11:01+00:00jsing2025-08-14T15:11:01+00:00urn:sha1:d31d4089b9ae677123f49cc1b071b80207baf184
Add detection of Multi-Precision Add-Carry Instruction Extensions on amd64.
s2n-bignum provides a number of fast multiplication routines that can
leverage these instructions.

There are no more consumers of crypto_cpu_caps_ia32(), so remove it.

Move AES-NI for ECB out of EVP.2025-07-22T09:13:49+00:00jsing2025-07-22T09:13:49+00:00urn:sha1:da7a63b669ad2a502ae120afede3fd850082e8b6
Make aes_ecb_encrypt_internal() replaceable and provide machine dependent
versions for amd64 and i386, which dispatch to AES-NI if appropriate.
Remove the AES-NI specific EVP methods for ECB.
This removes the last of the machine dependent code from EVP AES.

Move AES-NI from EVP to AES for CCM mode.2025-07-21T10:24:23+00:00jsing2025-07-21T10:24:23+00:00urn:sha1:b73facdeca098be7e538e556c1a293942db3110c
The mode implementation for CCM has two variants - one takes the block
function, while the other takes a "ccm64" function. The latter is expected
to handle the lower 64 bits of the IV/counter but only for 16 byte blocks.
The AES-NI implementation for CCM currently uses the second variant.
Provide aes_ccm64_encrypt_internal() as a function that can be replaced on
a machine dependent basis, along with an aes_ccm64_encrypt_generic()
function that provides the default implementation and can be used as a
fallback. Wire up the AES-NI version for amd64 and i386, change EVP's
aes_ccm_cipher() to use CRYPTO_ctr128_{en,de}crypt_ccm64() with
aes_ccm64_encrypt_internal()) and remove the various AES-NI specific
EVP_CIPHER methods for CCM.
