perf: introduce a perfrevlogwrite command

The command record times taken by adding many revisions to a revlog. Timing
each addition, individually. The "added revision" are recreations of the
original ones.

To time each addition individually, we have to handle the timing and the
reporting ourselves.

This command is introduced to track the impact of sparse-revlog format on
delta computations at initial storage time. It starts with the full text, a
situation similar to the "commit". Additions from an existing delta are better
timed with bundles.

The complaints from `check-perf-code.py` are not relevant. We are accessing
and "revlog" opener, not a repository opener.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
