glibc marks various allocation functions as `throw()`. This addition hasn't been a problem until we tried to enable C++17, where clang started complaining that we were redeclaring functions with mismatched exception specifications. Peculiarly, glibc declares virtually everything we redeclare as `throw()`, but clang only complains about the mismatches for a particular subset of functions. The approach taken in this patch is to add another potentially defined macro to malloc_decls.h, `NOTHROW_MALLOC_DECL`. This macro works exactly like `MALLOC_DECL`, except that clients can define `NOTHROW_MALLOC_DECL` to add appropriate `throw()` specifiers when declaring functions at global scope, and thereby avoid mismatched exception specifications.
