Building openssl with OPENSSL_SMALL_FOOTPRINT yelds only from 1% to 3%
decrease in size, dropping performance from 2% to 91%, depending on the
target and algorithm.
For example, using AES256-GCM with 1456-bytes operations, X86_64 appears
to be the least affected with 2% performance penalty and 1% reduction in
size; mips drops performance by 13%, size by 3%; Arm drops 29% in
performance, 2% in size.
On aarch64, it slows down ghash so much that I consider it broken
(-91%). SMALL_FOOTPRINT will reduce AES256-GCM performance by 88%, and
size by only 1%. It makes an AES-capable CPU run AES128-GCM at 35% of
the speed of Chacha20-Poly1305:
Block-size=1456 bytes AES256-GCM AES128-GCM ChaCha20-Poly1305
SMALL_FOOTPRINT 62014.44 65063.23 177090.50
regular 504220.08 565630.28 182706.16
OpenSSL 1.1.1 numbers are about the same, so this should have been
noticed a long time ago.
This creates an option to use OPENSSL_SMALL_FOOTPRINT, but it is turned
off by default unless SMALL_FLASH or LOW_MEMORY_FOOTPRINT is used.
Compiling with -O3 instead of -Os, for comparison, will increase size by
about 14-15%, with no measureable effect on AES256-GCM performance, and
about 2% increase in Chacha20-Poly1305 performance on Aarch64.
There are no Arm devices with the small flash feature, so drop the
conditional default. The package is built on phase2, so even if we
include an Arm device with small flash later, a no-asm library would
have to be built from source anyway.

The packages feed has a proposed package for a GOST engine, which needs
support from the main openssl library. It is a default option in
OpenSSL. All that needs to be done here is to not disable it.
Package increases by a net 1-byte, so it is not really really worth
keeping this optional.
This commit also includes a commented-out example engine configuration
in openssl.cnf, as it is done for other available engines.

No target is using kernel 3.18 anymore, remove all the generic

The removed packages are depending on kernel 3.18 only and are not used on

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Enable engine support by default. Right now, some packages require
this, so it is always enabled by the bots. Many packages will compile
differently when engine support is detected, needing engine symbols from
the libraries.
However, being off by default, a user compiling its own image will fail
to run some popular packages from the official repo.
Note that disabling engines did not work in 1.0.2, so this problem never
showed up before.
NPN support has been removed in major browsers & servers, and has become
a small bloat, so it does not make sense to leave it on by default.
Remove deprecated CONFIG_ENGINE_CRYPTO symbol that is no longer needed.

Openssh uses digest contexts across forks, which is not supported by the
/dev/crypto engine. The speed of digests is usually not worth enabling
them anyway. This changes the default of the DIGESTS option to NONE, so
the user still has the option to enable them.
Added another patch related to the use of encryption contexts across
forks, that ignores a failure to close a previous open session when
reinitializing a context, instead of failing the reinitialization.
Added a link to the Cryptographic Hardware Accelerators document to the
engine pacakges description, to provide more detailed instructions to
configure the engines.
Revert the removal of the OPENSSL_ENGINE_CRYPTO symbol, currently used
by openssh. There is an open PR to update openssh; when merged, this
symbol can be safely removed.

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.

Some package (e.g. libunbound) depend on OPENSSL_WITH_DEPRECATED. In some
situations it may happen that libunbound and openssl are only pulled in as
build dependencies, but are not enabled in .config.
In such cases, the defaults of symbols like OPENSSL_WITH_DEPRECATED are
ignored (as the whole symbol depends on PACKAGE_libopenssl), and config
symbol dependencies of libunbound aren't effective either (as libunbound
is not actually enabled).
This commit works around the issue by introducing a hidden negated symbol
OPENSSL_NO_DEPRECATED, which is always disabled when PACKAGE_libopenssl is
disabled, and ensures that OpenSSL is built with deprecated APIs in this
case. A user can still manage to break the build by explicitly enabling
libopenssl and disabling OPENSSL_WITH_DEPRECATED; the interaction between
build dependencies and config symbols will require further discussion.
