Add generic implementation handling and SHA2 impl
The skeleton file module/icp/include/generic_impl.c can be used for iterating over different implementations of algorithms. It is used by SHA256, SHA512 and BLAKE3 currently. The Solaris SHA2 implementation got replaced with a version which is based on public domain code of cppcrypto v0.10. These assembly files are taken from current openssl master: - sha256-x86_64.S: x64, SSSE3, AVX, AVX2, SHA-NI (x86_64) - sha512-x86_64.S: x64, AVX, AVX2 (x86_64) - sha256-armv7.S: ARMv7, NEON, ARMv8-CE (arm) - sha512-armv7.S: ARMv7, NEON (arm) - sha256-armv8.S: ARMv7, NEON, ARMv8-CE (aarch64) - sha512-armv8.S: ARMv7, ARMv8-CE (aarch64) - sha256-ppc.S: Generic PPC64 LE/BE (ppc64) - sha512-ppc.S: Generic PPC64 LE/BE (ppc64) - sha256-p8.S: Power8 ISA Version 2.07 LE/BE (ppc64) - sha512-p8.S: Power8 ISA Version 2.07 LE/BE (ppc64) Tested-by: Rich Ercolani <rincebrain@gmail.com> Tested-by: Sebastian Gottschall <s.gottschall@dd-wrt.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Tino Reichardt <milky-zfs@mcmilk.de> Closes #13741
