revset: stop serializing node when using "%ln"

Turning hundred of thousand of node from node to hex and back can be slow… what
about we stop doing it?

In many case were we are using node id we should be using revision id. However
this is not a good reason to have a stupidly slow implementation of "%ln".

This caught my attention again because the phase discovery during push make an
extensive use of "%ln" or huge set. In absolute, that phase discovery probably
should use "%ld" and need to improves its algorithmic complexity, but improving
"%ln" seems simple and long overdue. This greatly speeds up `hg push` on
repository with many drafts.

Here are some relevant poulpe benchmarks:
