Remove unnecessary inline functions capturing the contents of C library macros.

The C standard requires that these be provided as functions even if they're
also provided as macros, and a strict reading of the C++ standard library rules
suggests that (for instance) &::isdigit == &::std::isdigit, so these wrappers
are technically non-conforming.
