revset: add experimental relation and subscript operators
The proposed syntax [1] was originally 'set{n rel}', but it seemed slightly
confusing if template is involved. On the other hand, we want to keep 'set[n]'
for future extension. So this patch introduces 'set#rel[n]' ternary operator.
I chose '#' just because it looks like applying an attribute.
This also adds stubs for 'set[n]' and 'set#rel' operators since these syntax
elements are fundamental for constructing 'set#rel[n]'.

Our full contribution guidelines are in our wiki, please see: https://www.mercurial-scm.org/wiki/ContributingChanges If you just want a checklist to follow, you can go straight to https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist If you can't run the entire testsuite for some reason (it can be difficult on Windows), please at least run `contrib/check-code.py` on any files you've modified and run `python contrib/check-commit` on any commits you've made (for example, `python contrib/check-commit 273ce12ad8f1` will report some style violations on a very old commit).
