dagparser: replace format with str

check-code: catch format(), introduced in Python 2.6

commands: get rid of generic exception in debugbuilddag

check-code: fix check for any/all function The old check would only detect any/all at the beginning of a line. The regexp was probably just modeled after the preceding regexp which (correctly) finds the 'with' keyword at the beginning of a line. We now complain about 'any(' and 'all(' anywhere in a line, unless it is preceded by 'def'. This allows us to define our own compatibility wrapper in util and use 'util.any(' in the code.
