subrepo: do not traceback on .hgsubstate parsing errors Note that aborting in subrepo.state() prevents "repairing" commands like revert to be issued. The user will have to edit the .hgsubstate manually (but he probably had already otherwise this would not be failing). The same behaviour already happens with invalid .hgsub entries.

subrepo: ignore blank lines in .hgsubstate (issue3424) Reported by Sebastian Krysmanski <infomail@lordb.de>

largefiles: in putlfile, ensure tempfile's directory exists prior to creation Let R be a repo served by an hg daemon on a machine with an empty largefiles cache. Pushing a largefiles repo to R will result in a no-such-file-or-directory OSError because putlfile will attempt to create a temporary file in R/.hg/largefiles, which does not yet exist. This patch also adds a regression test for this scenario.
