Subject: [PATCH] version defines prefixed with name, full version

now the version variables will be prefixed with 'tmux-mem-cpu-load'. This way we
won't clash with any future dependency that might redefine those variables.
This is exactly how CMake does it in their code, see:

https://github.com/Kitware/CMake/blob/f3e92d281682ee482b1425675b9fccd372cd01f3/Source/CMakeVersion.cmake
https://github.com/Kitware/CMake/blob/6ae98ee18f6c35b93556a66dc0ce909d84aec18b/Source/cmVersionConfig.h.in
https://github.com/Kitware/CMake/blob/6ae98ee18f6c35b93556a66dc0ce909d84aec18b/Source/CMakeVersionCompute.cmake

the only difference is that they have functions that return the versions and I
use those variables directly.

https://github.com/Kitware/CMake/blob/6ae98ee18f6c35b93556a66dc0ce909d84aec18b/Source/cmVersion.cxx

Since the partial version variables are not used anywhere in the code we might
as well remove them from version.h.in. I've deciced to leave them for now, since
we might need them in the future.
