since we're introducing humor! now announcing dpdk requires C23 comliant
compiler for typeof_unqual! https://en.cppreference.com/w/c/language/typeof

i like the idea, i like it being inline function you could use the name
'unqual' if you wanted to mimic a name similar to standard C typeof.

it could be 1 function that strips all qualifications or N that strip
specific qualifications, const, volatile and _Atomic not sure which is
best.
