d9ae7cdd6d revsets: allow parenthesized expressions
We'll clearly want to allow parenthesized expressions once we have
infix operators (if not before). Let's prepare by allowing parentheses
already now.

This adds a `all_heads()` revset function, which contains all heads in
the view, i.e. including non-public heads and obsolete heads.

88904e2b63 revsets: add support for function syntax
This adds `parents(foo)` and `ancestors(foo)` as alternative ways of
writing `:foo` and `*:foo`. 

I haven't added support for for whitespace yet; the parsing is very
strict. The error messages will also need to be improved later.
