evolve: adapt for deprecated ui.progress()
This makes a wrapper that has an interface like ui.progress() even
though that's the old interface that will eventually go away. That's
because it's a lot easier to convert from the ui.progress() to the
ui.makeprogress() interface than the other way around. Once we no
longer support hg<4.7, we can migrate our callers to ui.makeprogress()
and drop the wrapper.
Doc is generated with sphinx.
You can generate the doc with:
```
make
```
# Tutorials
For updating the tutorials, you need to have the docgraph extension installed
(https://pypi.python.org/pypi/hg-docgraph).
Then run the test-topic-tutorial.t and test-tutorial.t to update the output if
needed.
You'll need the dot binary (likely installed by the graphviz package in your
package manager) in order to have graphviz graphs rendered in the html output.
Simply run make in the docs directory should takes care of the conversion of
the tutorial .t files into .rst files. Then sphinx should do the rest of the
jobs by rendering graphviz graphs.
