All supported compilers have supported deduction guides in C++17 for a
while, so this isn't necessary anymore.

C++03 didn't support `explicit` conversion operators;
but Clang's C++03 mode does, as an extension, so we can use it.
This lets us make the conversion explicit in `std::function` (even in '03),
and remove some silly metaprogramming in `std::basic_ios`.
Drive-by improvements to the tests for these operators, in addition
to making sure all these tests also run in `c++03` mode.

This can also serve as a pseudo "announcement" for how we should order these headers going forward (note: double underscores go before other headers).

This makes it clear that headers like <memory> which include auto_ptr
only do that when compiling under an older Standard, or when the removed
feature is explicitly requested.
