patman: Fix up checkpatch parsing to deal with 'CHECK' lines
checkpatch has a new type of warning, a 'CHECK'. At present patman fails with these, which makes it less than useful. Add support for checks, making it backwards compatible with the old checkpatch. At the same time, clean up formatting of the CheckPatches() output, fix erroneous "internal error" if multiple patches have warnings and be more robust to new types of problems.
