(pair::pair): Eliminate the redundant pair(U1&&, U2&&) constructor.
Add lvalue pair<U1, U2> constructor to handle non-const pair lvalues.
Remove the old variadic constructor, and instead provide several
variadic constructors that avoid failing when attempting to
initialize a pointer from a null pointer constant.

initialization of pointers from the null pointer constant.
