Move some files of programs to the framework

[ronald-cron-arm]

• Move programs/demo_common.sh and programs/test/dlopen_demo.sh to scripts.
• Move programs/test/metatest.c, programs/test/query_compile_time_config.c, programs/test/query_config.h, programs/test/query_included_headers.c and programs/test/zeroize.c to ./tests/programs (to be created).

At time of writing, the files above are identical in development and 3.6.
Adapt all.sh components using dlopen_demo.sh
Adapt the make and CMake build systems of development and 3.6.
No build scripts in the framework. For CMake, use link_to_source to create a symbolic link or copy the files from tests/programs in the build tree. The program executables are still created in programs/test of development and 3.6.
