bundle2: add a "check:heads" handler This part is intended to hold the same role as the `heads` argument of the unbundle function. The client fill it with the known heads at bundle time and the server will abort if its heads changed.

repoview: make the conversion from node to rev explicit while computing hidden You cannot use `repo[...]` lookup here. 1. It is slow 2. It is very likely to trigger a hidden computation itself, entering an infinite loop.

repoview: drop duplicated lookup We are already looking for local tags on the line above. We can safely drop this extra lookup.

tests: coverage of convert and filemap include and the default of include all

largefiles: remove no more referred "getoutgoinglfiles()"

largefiles: use "outgoinghooks" to avoid redundant outgoing check Before this patch, "hg outgoing" invokes "findcommonoutgoing()" not only in "commands.outgoing()" but also in "overrides.overrideoutgoing()" (via "getoutgoinglfiles()"), when largefiles is enabled. The latter is redundant. This patch uses "outgoinghooks" to avoid redundant outgoing check. Newly introduced function "overrides.outgoinghook()" is registered into "outgoinghooks" to get the result of outgoing check in "commands.outgoing()". It invokes "lfutil.getlfilestoupload()" directly with the result of outgoing check to avoid redundant outgoing check in "getoutgoinglfiles()": "sort()" is needed, because "lfutil.getlfilestoupload()" doesn't sort the result of it. This patch also omits "if toupload is None" ("No remote repo") case, because failure of looking remote repository up should raise exception in "commands.outgoing()" before invocation of "outgoinghooks". Newly added "hg outgoing --large --graph" tests examine "outgoinghooks" invocations in "hg outgoing --graph" code path.

outgoing: introduce "outgoinghooks" to avoid redundant outgoing check This patch introduces "outgoinghooks" to avoid redundant outgoing check for "hg outgoing" in other than "commands.outgoing" (or utility functions used by it).
