log: changed implementation to use graphlog code
Now that revsets work in a lazy way, log code can be changed to parse every
option into a revset and then evaluate it lazily.
Now expressions like
"hg log -b default -b ."
are converted into a revset using the same code as graphlog.
Failed qimport of patches from files should cleanup by recording successfully
imported patches in series file.
