match: remove special-casing of always-matching patterns in patternmatcher This moves the optimization for patterns that match everything to the caller, so we can remove it from patternmatcher. Note that we need to teach alwaysmatcher to use relative paths now in cases like "hg files .." from inside mercurial/, because while it still matches everything, paths should be printed relative to the working directory.

match: move normalize() call out of matcher constructors By passing in the result of the normalize() call, we prepare for moving the special handling of patterns that always match out of the patternmatcher. It also lets us remove many of the arguments from the matcher, because they were passed only the the normalize function (we could have removed the arguments by binding them to the function instead of moving the normalize() call out).
