revset: skip legacy lookup for revspec wrapped in 'revset(...)'...

revset: skip legacy lookup for revspec wrapped in 'revset(...)' Currently, multiple labels can take forms that can be confused with revset (eg: "rev(0)" is a valid tag). Since we look up for tags before evaluating revset, this means a tag can shadow a valid revset at any time. We now enforce the strict revset parsing when wrapped with 'revset(...)'. For now, This only work on a whole revspec (but can be used within the revset without effect). This might change in the future if we improve the implementation. The feature is undocumented for now, keeping it in the experimental namespace. In case a better approach to achieve the same goal is found. The syntax looks like a revset but is not implemented as such for now. Since the goal is to avoid some preprocessing that happens before revset parsing, we cannot simply implement it as a revset predicate. There was other approaches discussed over the mailing-list but they were less convincing. Having a configuration flag to disable legacy lookup have been considered but discarded. There are too many common uses of ambiguous identifier (eg: '+', '-' or '..') to have the legacy lookup mechanism turned off. In addition, the approach can control the parsing of each revset, making it more flexible. For example, a revset used as the value of an existing configuration option (eg: pushrev) could enforce its resolution as a revset (by using the prefix) while user inputs would still use the legacy lookup. In addition of offering a way to unambiguously input a revset, this prefix allow skipping the name lookup providing a significant speedup in some case.
