util: allow trailing semicolons on define_trivial_cleanup_func lines
Emacs C indenting really gets confused by these lines if they carry no trailing semicolon, hence let's make this nicer for good old emacs. The other macros which define functions already do this too, so let's copy the scheme here. Also, let's use an uppercase name for the macro. So far our rough rule was that macros that are totally not function-like (like this ones, which define a function) are uppercase. (Well, admittedly it is a rough rule only, for example function and variable decorators are all lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and also they at least got underscore prefixes.) Also, the macros that define functions that we already have are all uppercase, so let's do the same here...
