Reduce the verbosity of SDT trace points for DTrace by defining several
wrapper macros that allow trace points and arguments to be declared
using a single macro rather than several. This means a lot less
repetition and vertical space for each trace point.
Use these macros when defining privilege and MAC Framework trace points.
