Add parentheses around macro arguments

This fixes actual problem reported by clang: in client.cpp,
maplist(..., i!=0); expands to mapshrink(!i!=0, ...) which
is interpreted as (!i)!=0 instead of !(i!=0). Nice example why
macros are evil. By happy coincidence, this still works correctly,
but fix this nevertheless and add some more parens in other expressions
just for the case.
