revset: try to handle hyphenated symbols if lookup callback is available Formerly an expression like "2.4-rc::" was tokenized as 2.4|-|rc|::. This allows dashes in symbols iff the whole symbol-like string can be looked up. Otherwise, it's tokenized as a series of symbols and operators. No attempt is made to accept dashed symbols inside larger symbol-like string, for instance foo-bar or bar-baz inside foo-bar-baz.

revset: pass a lookup function to the tokenizer

parser: allow passing a lookup function to a tokenizer This will allow us to dynamically handle hyphenated symbols in revsets.

benchmark-revset: add full version of benchmarked revset All revsets added to benchmark so far are aimed to show an improvement of performance from laziness. We had more wider version to track impact of laziness on them.
