demandimport: make module ignores a set (API)...

demandimport: make module ignores a set (API) The list of modules to ignore is used for membership testing. Yet it is defined as a list. Sets are more efficient for membership testing. So this commit converts the module list to a set. Since we took an API hit, I renamed the variable to further clarify the change. This appears to reduce the CPU time for running 300 invocations of `hg log -r. -T '{rev}'` on my i7-6700K: before: 18.64s after: 18.44s Differential Revision: https://phab.mercurial-scm.org/D3440
