As a first step, implement the equivalent of what was implemented in the
now deprecated libbitcoinconsensus header. Also add a test binary to
exercise the header and library.
Unlike the deprecated libbitcoinconsensus the kernel library can now use
the hardware-accelerated sha256 implementations thanks for its
statically-initialzed context. The functions kept around for
backwards-compatibility in the libbitcoinconsensus header are not ported
over. As a new header, it should not be burdened by previous
implementations. Also add a new error code for handling invalid flag
combinations, which would otherwise cause a crash.
The macros used in the new C header were adapted from the libsecp256k1
header.
To make use of the C header from C++ code, a C++ header is also
introduced for wrapping the C header. This makes it safer and easier to
use from C++ code.

fa7ca182a9 ci: Print inner env (MarcoFalke)
Pull request description:
The outer env is printed when the `/tmp/env-$USER-$CONTAINER_NAME` is created. There is also a separate env printed when building the container image (usually with default values).
To confirm that the inner container env is correctly derived from the outer env, and not from the default build env, print it a third time.
