C overhead fixes (#20402)
* [C][Client] Remove redundant casts Don't explicitly cast void pointers as it's unnecessary in C, but leave printf arguments untouched to avoid setting off -Wformat. * [C][Client] Cosmetic: remove unnecessary parens, align some lines * [C][Client] Reduce number of unnecessary strlen() calls
