patches: release the GIL while applying the patch This will allow multiple threads to apply patches at the same time.

perfbranchmap: allow to select the filter to benchmark Running the branchmap computation on all filter levels can be expensive. Narrowing the run to some specific filters can speed up benchmarking time when working only on a subset of filter levels.

perfbranchmap: display 'unfiltered' for unfiltered performance This is slightly clearer than "None" and will help with coming changes to select the filter level we want timing for.

py3: two more narrow tests passing Differential Revision: https://phab.mercurial-scm.org/D2390

narrowbundle2: more kwargs native string fixes This gets test-narrow.t to *almost* pass. Something appears to be borked in producing bundles, but only some of the time? I'm lost, but this change is at least a clear improvement. # skip-blame just more r prefixes on strings Differential Revision: https://phab.mercurial-scm.org/D2389

py3: whitelist another 11 passing tests This is most of narrow. There's still some buglets at the margins, but it's pretty good progress for not a lot of work. Differential Revision: https://phab.mercurial-scm.org/D2388

narrowbundle2: use native string to get kwargs from dict # skip-blame just some r prefixes on strings Differential Revision: https://phab.mercurial-scm.org/D2387

narrowbundle2: drop legacy getcgkwargs variable I think this was around as part of support for some older hg internals. It's not needed any more. Differential Revision: https://phab.mercurial-scm.org/D2386

fancyopts: add support for custom multi-arg opts in fancyopts.py This allows for more complex multi-arg opt logic, such as "--sum 1 --sum 2" -> 3, "--csv alice,bob --csv charlie" -> ["alice","bob","charlie"]. The current support for callables is insufficient for this. This is done by introducing a 'customopt' class which can be extended for more powerful opts logic. All existing opt-types are converted to use this class, simplifying the fancyopts() logic. Differential Revision: https://phab.mercurial-scm.org/D2090

narrowchangegroup: remove backwards compatibility with old hg This was missed in the initial import of narrowhg, but was detected by the Python 3 porting effort once I got enough other things in narrow fixed. Differential Revision: https://phab.mercurial-scm.org/D2370

narrowbundle2: replace map() with equivalent list comprehension The result of this gets used as a list in core code, so the generator returned by map() on Python 3 is a problem. Differential Revision: https://phab.mercurial-scm.org/D2369

narrowbundle2: this dict contains native strings, look kws up as such We could also do a byteskwargs dance, but that seems silly given that we only need this one element. Differential Revision: https://phab.mercurial-scm.org/D2368

py3: use list comprehensions instead of filter where we need to eagerly filter These two uses of filter() are then checked for truthiness, but on Python 3: >>> bool(filter(None, [])) True So we need to stop depending on that. Fortunately it's easy to replace the filter with an equivalent list comprehension. Differential Revision: https://phab.mercurial-scm.org/D2364

narrow: use list comprehension instead of filter for filtering lists filter() returns a generator on Python 3, which causes these filters to break things. Differential Revision: https://phab.mercurial-scm.org/D2363

debuginstall: strip double quotes from editorbin on Windows The unconditional posix style shlex.split() prior to 94a1ff16f362 handled this. This isn't mutually exclusive with stripping the quotes in util.findexe()- if the editor can't be found, this command prints out the string, inside single quotes.

hgweb: show each obsfateentry on its own line Commits with more than one reason for being obsolete used to just show obsfate entries all on one line, and that doesn't look good. Let's show each entry on its own line. In paper and coal the lines are simply split using a <br> element, and in other hgweb themes each entry has its own table header. This is done by analogy with changeset parents and children -- in paper and coal they are all put into one table row, and everywhere else each one gets a separate row.

tests: check obsolete changeset with two obsfate entries It's more interesting to see how a changeset that was both rewritten and split looks in hgweb.
