log: speed up hg log <file|folder>
This patch makes hg log <file|folder> faster by using changelog.readfiles
instead of changelog.read.
On our large repos for hg log <file|folder> -l5 operations that were taking:
- ~8s I see a 25% improvement
- ~15s, I see a 35% improvement
For recently modified folder/file, the difference is negligible as we don't
have to consider many revisions.
