sparse-revlog: handle nullrev in index_get_start
The more generic index_get method handle nullrev fine, we apply the same logic
here.

revlog: introduce a constant for nullrev in `revlog.c`
The value is important enough to be explicitly tracked.

rust: translation of missingancestors
This is as direct as possible a translation of the ancestor.missingancestors
Python class in pure Rust. The goal for this changeset is to make it easy
to compare with the Python version.
We also add to Python tests the cases that helped us develop and debug
this implementation.
Some possible optimizations are marked along the way as TODO comments

contrib: provide a small script that draw performance plot
We have been using this script to look into the result of various runs of the
`hg perfrevlogwrite` command. It seems useful enough to be shared more widely.

delta: filter nullrev out first
When picking a potential candidate, we filter them on various criteria. The
"different from nullrev" criteria is very fast to compute and we should
process it first.

perf: report more of the higher range in perfrevlogwrite
Since the delta chain length is limited to 1000 revisions, we get a new
snapshot about every 1000 revisions. If we assume that the snapshot will be
most of the slowest revision, the current display (99% and max) are not very
precise in their area. We now include more information about this space in the
default report.

help: present boolean arguments as "--[no-]foo"
This should make it much more discoverable (we document it in `hg help
flags`, but most users don't think to look there).
Note that flags that default to None (and not False) will not get this
new presentation. We can change the defaults to False later for flags
where it makes sense (probably almost all boolean flags).

help: use "default: on" instead of "default: True"
"True" feels like a Python thing and not something that users should
see.

check-commit: disallow capitalization only right after topic
It should be okay to write "topic: change 'default: True' to 'default:
on'".
