hgweb: add revset syntax support to search

This mode is used when all the conditions are met:
- 'reverse(%s)' % query string can be parsed to a revset tree
- this tree has depth more than two, i.e. the query has some part of
revset syntax used
- the repo can be actually matched against this tree, i.e. it has only existent
function/operators and revisions/tags/bookmarks specified are correct
- no revset regexes are used in the query (strings which start with 're:')
- only functions explicitly marked as safe in revset.py are used in the query

Add several new tests for different parsing conditions and exception handling.
