graphmod: use revsets internally

Thanks for the idea and most of the implementation to Klaus Koch

Backs revisions() and filerevs() with DAG walker which can iterate through
arbitrary list of revisions instead of strict one by one iteration from start to
stop. When a gap occurs in a revisions (i.e. in file log), the next topological
parent within the revset is searched and the connection to it is printed in the
ascii graph.

File graph can draw sometimes more connections than previous version, because
graph is produced according to the revset, not according to a file's filelog.

In case the graph contains several branches where the left parent is null, the
graphs for each are printed sequentially, not in parallel as it was a case
earlier (see for example the graph for README in hg-dev).
