run-tests: added 'cuser', 'csys' time info in report.json file This patch adds up a 'cuser' and 'csys'(cputime) info in report.json file which generated when --json is enabled while testing. Now the new format of report.json file is as below. testreport ={ "test-success.t": { "csys": "1.041", "cuser": "1.041", "result": "success", "time": "2.041" } "test-failure.t": { "csys": "1.041", "cuser": "1.041", "result": "failure", "time": "4.430" } "test-skip.t": { "csys": "1.041", "cuser": "1.041", "result": "skip", "time": "3.754" } }

obsolete: use C code for headrevs calculation Previously, if there were filtered revs the repository could not use the C fast path for computing the head revs in the changelog. This slowed down many operations in large repositories. This adds the ability to filter revs to the C fast path. This speeds up histedit on repositories with filtered revs by 30% (13s to 9s). This could be improved further by sorting the filtered revs and walking the sorted list while we walk the changelog, but even this initial version that just calls __contains__ is still massively faster. The new C api is compatible for both new and old python clients, and the new python client can call both new and old C apis.

revset: simplify orderedlazyset creation in spanset method We can simply use the `self.isascending` value instead of more complex if/else clause. This get the code simpler. Benchmarks show no performances harmed in the process.
