Eric Rahm bf49ee0a6a Bug 1403083 - Part 1: Properly disable string functions for invalid char types. r=froydnj ...

In order to properly disable template functions with `std::enable_if` we need
to use the resulting type. This only works if we use a dependent type in the
template params, hence the need to shadow the `T` param.

Proper usage is now of the form:

template<typename Q = T, typename EnableIfChar = CharOnlyT<Q>>
Foo();
