commands: support passing depth to hg.clone() This will allow extensions to add --depth or other arguments to control depth fetching. Differential Revision: https://phab.mercurial-scm.org/D5164

filelog: add a hasnode() method (API) Missing in the file storage interface is the ability to query whether a specified value is a known node. This commit defines that interface member and implements it on the revlog and sqlite file stores. Storage unit tests have been added. The revlog implementation is a bit more complicated because index lookups don't consistently raise the same exception. For SQLite, we can simply look for a key in a dict.

lfs: consult the narrow matcher when extracting pointers from ctx (issue5794) I added a testcase for lfs to all narrow tests, and the following failed: test-narrow-acl.t test-narrow-exchange.t test-narrow-patterns.t test-narrow-strip.t test-narrow-trackedcmd.t test-narrow-widen.t test-narrow.t The first two still have errors in the pretxnchangegroup on clone and (receiving a) push, which I'm still looking into (4d63f3bc1e1a fixed something in this area already). These two modified tests seem to cover the things that failed in the remaining narrow tests, i.e. `hg tracked` and `hg strip`, so I didn't bother enabling the testcases elsewhere. Maybe we should, but it's 68 tests total.

statprof: fix overflow while skipping boilerplate parts I got IndexError randomly because of stack[i] where i = len(stack).

statprof: fix indent level of fp.write() (issue6004) It was changed at 9d3034348c4f by mistake.

py3: stringify setupversion on Windows This was stringified a few lines above for non Windows platforms, but `version` remains bytes. The old code effectively undid the conversion, and triggered a warning in setuptools when building.
