py3: introduce and use pycompat.getargspec This is getfullargspec on py3, which means we can't use namedtuple named accessors for all fields (eg keywords from getargspec is varkw from getfullargspec, with the same meaning). Solves some warning issues on Python 3. I didn't clean up httpclient because that's vendored code I think we should probably discard, and I didn't touch the manpage generator for now either.

py3: whitelist more passing tests I had some good success tonight with histedit tests. test-histedit-fold.t is now low-hanging fruit: it is only failing because the logic for setting environment variables in hook.py is slightly busted. Specifically, hook.py line 142 should be making sure it puts strings in the env dict, not bytes, to avoid b'' goo in environment variables.

histedit: binascii.unhexlify (aka node.bin) throws new exception type on py3 Lucky for us, the exception type exists on 2.7, so we can include it in the except block without any extra work. Differential Revision: https://phab.mercurial-scm.org/D2244

treemanifest: add an optimized __nonzero__() We use bool(manifest) in at least some places: localrepo.py:1730 hgweb/webcommands.py:524 Since the treemanifest class doesn't define __nonzero__() (before this patch), bool(manifest) will instead call __len__(), which can be slow for treemanifests. This patch may make a noticeable difference in the localrepo case above, but that only happens when committing a merge and I haven't timed it. Note that Durham already added a __nonzero__ implementation to manifestdict in b19291e5d506 (manifest: add __nonzero__ method, 2016-11-03).

histedit: fix silly bug that was unpacking a bytestr before writing it I have this foggy notion that popbuffer() might have returned a list in the past, but it doesn't anymore, and this was breaking on Python 3.

narrowspec: move module into core Having support for parsing the narrow specification in core is necessary for moving many other parts of narrow to core.

convert: fix line ending of mapfile and commit.desc file Follows up 42a393ea56d2. CRLF vs LF doesn't really matter as we do strip() or rstrip() on read, but mixing them isn't nice. So let's restore the old behavior. I don't know whether CVS/Root, CVS/Repository, and ~/.cvspass are written in native line ending, so I leave them read as binary files.

py3: port string formatting `skipped` is a set of integer revs here. So cast integers to strings using %d. None doesn't cast to an empty string on Python 3. So use '' explicitly. Differential Revision: https://phab.mercurial-scm.org/D2146

cmdutil: convert the prefetchfiles() hook to a callback mechanism (API) Yuya suggested a list of callbacks instead of function wrapping. This means that one extension can't block another from processing the list. .. api:: File prefetching is now handled by registering a callback with scmutil.fileprefetchhooks.
