The patches to the /dev/crypto engine were commited to openssl master,
and will be in the next major version (3.0).
Changes:
- Optimization in computing a digest in one operation, saving an ioctl
- Runtime configuration options for the choice of algorithms to use
- Command to dump useful information about the algorithms supported by
the engine and the system.
- Build the devcrypto engine as a dynamic module, like other engines.
The devcrypto engine is built as a separate package by default, but
options were added to allow building the engines into the main library.

Add a patch to enable the option to change the default ciphersuite list
ordering to prefer ChaCha20 over AES-GCM. This is used by default for
all platforms, except for x86_64 and aarch64. The assumption is that
only the latter have AES-specific CPU instructions and asm code that
uses them in openssl. Chacha20Poly1305 is 3x faster than AES-256 in
systems without AES instructions, with an equivalent strength.
Disable error messages by default except for devices with small flash or
RAM, to aid debugging.
Disable ASM by default on arm platform with small flash. Size
difference on mips and powerpc, the other platforms with small flash
devices, are not really relevant (using 100K as a threshold). All of
the affected platforms are source-only anyway.
