[stage2] Remove printk, introduce UTF-8 console stdio

Merge branch 'master' of github.com:SciresM/Atmosphere-NX

[stage1] support utf8 in fatfs

Replace std::make_tuple with simpler syntax (#77) ...

* boot2: Simplify g_additional_launch_programs

It appears that Stratosphère is targeting C++17. In C++17,
std::make_tuple is not required for initialisating a tuple anymore.
Same thing, but less typing

* Replace std::make_tuple with {}

More readable and less noise. Also fixes two missing return statements.

ipc_templating: Avoid depending on order of evaluation (#83) ...

f(x, x++) is unspecified behaviour in C++. An implementation could
evaluate arguments from left to right or from right to left.

`T(r.Buffers[a_index], r.BufferSizes[a_index++])` might
access the wrong buffer if `a_index++` is evaluated before the first
argument.

Fixes -Wsequence-point warnings

Use the bloated string formatting functions from newlib

Instead of passing FatFS structs around, unmount; other changes
