changelog: lazily parse description
Before, the description field was converted to a localstr at parse
time. With this patch, we store the raw description and convert to
a localstr when it is first accessed.
We see a revset speedup for revsets that don't access the description:
author(mpm)
0.896565
0.914234
0.869085
date(2015)
0.878797
0.891980
0.862525
extra(rebase_source)
0.865446
0.912514
0.871500
author(mpm) or author(greg)
1.801832
1.860402
1.791589
date(2015) or branch(default)
0.968276
0.994673
0.974027
author(mpm) or desc(bug) or date(2015) or extra(rebase_source)
3.656193
3.721032
3.643593
As you can see, most of these revsets are already faster than from
before this refactoring: we have already offset the performance
loss from the introduction of the new class representing parsed
changelog entries!
