It includes changes to:
- tests/Makefile: build the library for client and server in different
folders. It mimica the libtestdriver1 behavior (without functions
renaming though).
- tests/scripts/all.sh: helper function to build for client and
server with some default configuration for each of them.
- crypto_spe.h: this is dummy file taken from the already existing
tests. It's just meant to pacify the compiler, not to provide
something useful. It will likely be changed in the future.
