Silence unused result warnings on newer compilers

Browse Source 
Newer versions of GCC and Clang are not satisfied by a cast to void,
this fix is adapted from glibc's solution.

New wrapper function ignore_result should be used when a function with
explicit _unused_attribute_ wrapper is called whose result will not be
handled.
