revpair: smartset compatibility

Since recent revset changes, revrange now return a smartset. This smart set
probably does not support indexing (_addset does not). This led to crash.
Instead when the smartset is ordered we use the `min` and `max` method of
smart set. Otherwise we turn is into a list and use indexing on it.

The tests have been updated to catch such regression.

import unittest, sys

def main(modulename):
    '''run the tests found in module, printing nothing when all tests pass'''
    module = sys.modules[modulename]
    suite = unittest.defaultTestLoader.loadTestsFromModule(module)
    results = unittest.TestResult()
    suite.run(results)
    if results.errors or results.failures:
        for tc, exc in results.errors:
            print 'ERROR:', tc
            print
            sys.stdout.write(exc)
        for tc, exc in results.failures:
            print 'FAIL:', tc
            print
            sys.stdout.write(exc)
        sys.exit(1)
