py3: replace bytes[n] with slicing in checkwinfilename()

py3: manually escape control character to be embedded in win filename error

py3: replace str(None) with literal in convcmd.py

py3: remove use of str() in hgwebdir '%d' can't be used here since port may be either integer or byte string.

config: use copy-on-write to improve copy performance Previously, chg's `verify` call could take 30+ms loading and checking new config files. With one socket redirection, that adds up to around 70ms, which is a lot for fast commands (ex. `bookmark --hidden`). When investigating closer, A lot of time was spent on actually spent on ui copying, which is mainly about `config.config` and `dict` copying. This patch makes that 20x faster by adopting copy-on-write. The copy-on-write is performed at config section level. Before: In [1]: %timeit ui.copy() 100 loops, best of 3: 2.32 ms per loop After: In [1]: %timeit ui.copy() 10000 loops, best of 3: 128 us per loop 2ms may look not that bad, but it adds up pretty quickly with multiple calls. A typical chg run may call it 4 times, which is about 10ms. Differential Revision: https://phab.mercurial-scm.org/D808

rebase: move bookmarks with --keep (issue5682) This is a regression caused by 3b7cb3d17137. We have documented the behavior in rebase help: Rebase will destroy original commits unless you use "--keep". It will also move your bookmarks (even if you do). So let's restore the old behavior. It is done by changing `scmutil.cleanupnodes` to accept more information so a node could have different "movement destination" from "successors". It also helps simplifying the callsite as a side effect - the special bookmark movement logic in rebase is removed. Differential Revision: https://phab.mercurial-scm.org/D727

cleanupnodes: rename "mapping" to "replacements" The next patch will pass in overrides for bookmark moves, which is a mapping itself, so let's rename "mapping" to "replacements" to distinguish them better. Differential Revision: https://phab.mercurial-scm.org/D749

cleanupnodes: separate out bookmark destination calculation from actual update We will soon want to pass in overrides for bookmark movements and this will make that patch simpler. I also think this makes the code easier to follow regardless of the later patch. Differential Revision: https://phab.mercurial-scm.org/D748

ui: check for progress singleton when clearing progress bar (issue5684) A combination of wrapping `ui` and progress bars interrupted by exceptions can lead to the progress bar not being cleared when the exception error is printed. This results in corrupted-looking output like this: ``` updating [===============================> ] 1/2u nresolved conflicts (see hg resolve, then hg rebase --continue) ``` This is because in `ui._progclear`, we only check the local reference to the progress bar, not whether or not there is an instance of the singleton. When a progress bar is interrupted by an exception, the exception printing in `scmutil.callcatch` uses the original instance of the `ui` object, not the wrapped copy that has `_progbar` set. When consider whether or not to clear the progress bar, check for the existence of the singleton, rather than just whether or not we have a local reference to it.
