Summary:
Remove ui.progress as a method of updating progress. All progress bars now go
through new-style progress bars.
This also splits out the rendering of progress bars from the reporting of
progress. All tests are updated to use new-style debug progress bars, which
simply report the position of the progress bar. Rendering of progress bars
will be tested separately once the progress bar engine has been rewritten.

New-style progress bars should only update if there has been any progress since

Summary:
Previously, when looking for a treemanifest we'd inspect the flat
manifest revlog to get a hint for which nearby manifests might exist. This
assumed the data was in the flat manifest though, and if it wasn't it threw an
exception which caused us to not look at the server for the tree.
This commit fixes the case where the flat manifest doesn't have the commit, so
it can still look at the server.

Summary:
There were recent complains about both quality [1] [2] and performance [3]
of the current word diff algorithm.
The current algorithm is actually bad in various ways:
- Lines could be matched across hunks, which is confusing (report [1]).
- For short lines, they can fail "similarity" check, which means they
won't be highlighted when they are expected to be (report [2]).
- Various performance issues:
- Using difflib implemented by pure Python, which is both slow and
suboptimal comparing with xdiff.
- Searching for matched lines across hunks could be O(N^2) if there are
no match found.
Thinking it in a "highlight" way is actually tricky, consider the following
change:
```
# before
foo = 10
# after
if True:
foo = 21 + 3
```
It's obvious that "10" and "21 + 3" need highlighting because they are
different. But what about "if True:"? In theory it's also "different" and
need highlighting. How about purely inserted or deleted hunks then?
Highlighting all of them would be too noisy.
This diff rewrites the word diff algorithm. It differs in multiple ways:
1. Get rid of "matching lines by similarity" step.
2. Only diff words within a same hunk.
3. Dim unchanged words. Instead of highlighting changed words.
4. Treat pure insertion or deletion hunks differently - do not dim or
highlight words in them.
5. Use xdiff instead.
6. Use a better regexp to split words. This reduces the number of tokens sent
to the diff algorithm.
1, 2, 5, 6 help performance. 1, 2, 3, 4 make the result more predictable and
trustworthy. 3 avoids the nasty question about what to highlight. 3 and 4 makes
it more flexible for people to tweak colors. 6 makes the result better since it
merges multiple space tokens into one so xdiff will less likely miss important
matches (than meaningless matches like spaces).
"bold" and "underline" were removed so the changed words will have regular
red/green colors. The output won't be too "noisy" even in cases where code are
changed in a way that inline word matching is meaningless. For people who want
more contrast, they can set:
[color]
diff.inserted.changed = green bold
diff.deleted.changed = red bold
Practically, when diffing D7319718, the old code spends 4 seconds on finding
matched lines preparing for worddiff:
