checkpatch: add checks for question mark and colon spacing
Add checks for the question mark colon operator spacing, and also check the other uses of colon. Colon means a number of things: - it introduces the else part of the ?: operator, - it terminates a goto label, - it terminates the case value, - it separates the identifier from the bit size on bit fields, and - it is used to introduce option types in asm().
