Before we had the following scheme: mempool_enabled() would check mempool_use_allowed, and libsystemd-shared would be linked with a .c file that provides mempool_use_allowed=true, while other things would linked with a different .c file with mempool_use_allowed=false. In the new scheme, mempool_enabled() itself is a weak symbol. If it's not found, we assume false. So it only needs to be provided for libsystemd-shared, where it can return false or true. test-set-disable-mempool is libshared, so it gets the symbol. But then we actually disable the mempool via envvar. mempool_enable() is called to check its return value directly.
