util: remove datapath and swith users over to resourceutil The util module no longer needs the datapath for injecting it into the i18n module, so we can remove it from there and update other users. Differential Revision: https://phab.mercurial-scm.org/D7436

i18n: get datapath directly from resourceutil The new resourceutil module is lower in the dependency graph, so we can depend directly on it and won't have to depend on the util module to inject the datapath. Differential Revision: https://phab.mercurial-scm.org/D7435

util: move definition of datapath to resourceutil Since this means moving the function into a subdirectory, we have to compensate by adding another layer of os.path.dirname(). Differential Revision: https://phab.mercurial-scm.org/D7434

procutil: move mainfrozen() to new resourceutil.py The i18n module practically depends on procutil for mainfrozen() but since procutil depends on i18n, it would be a circular dependency if i18n depended directly on procutil. The cycle is currently resolved by having the higher-level util module calculate the "datapath" and inject it into i18n. Extracting mainfrozen() to a new module lets us clean up the dependencies.
