libstratosphere: Cleanup resources when doing OutSession for domains.

Modernize C++ usage (#144) ...

* Stratosphere: Use modern C++ idioms in some places

* algorithms like std::for_each are used instead of raw loops

* Stratosphere: Replace more raw loops with algorithms

* Stratosphere: Add a utility predicate function to test for equality with a reference element

This can be used to rewrite some common raw loops using algorithms instead

* fs.mitm: Use variant

* fs.mitm: Use enum class

* fs.mitm: Turn RomFSSourceInfo::Cleanup into a destructor

This obsoletes the need for a custom deleter in other places

* fs.mitm: Use enum class some more

* fs.mitm: Use unique_ptr

* fs.mitm: Simplify initialization

* Stratosphere: Simplify initialization

* fs.mitm: Use unique_ptr (fix memory leak along the way)

The previous code was using "delete" rather than "delete[]"

* fs.mitm: Use vector::emplace_back rather than push_back

emplace_back constructs elements in-place, hence avoiding a redundant element copy.

* Stratosphere: Replace more raw loops with algorithms

* Stratosphere: Use unique_ptr

* fs.mitm: Replace more raw loops with algorithms

* Stratosphere: Prefer move-construction over copy-construction when moving sink parameters around

Make PM Compile. Note: Currently broken.

fs.mitm: WIP LayeredFS impl (NOTE: UNUSABLE ATM) ...

Also greatly refactors libstratosphere, and does a lot of other things.
There is a lot of code in this one.

libstratosphere/fs.mitm: Push WIP support for Domains. Not yet fully working.

fs.mitm: Add HANS-style redirection for System Data Archives.

fs.mitm: Get Title ID on fsp-srv init, Add worker to handle subinterfaces.

Use "final" and "override" where appropriate (#117)

Ignore unused-but-set-variable in ipc_templating.h

libstratosphere: Make boolean autoparsing match official semantics.

ProcessManager: Fix Synchronization. Now works on 1.0.0 hardware.

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

ProcessManager: Implement core process management logic.

ProcessManager: Fill out ProcessTracking::Initialize()

Stratosphere: Add IPC templating for non-member functions.

Loader: Fix bugs ldr:ro, Loader now works fully on hardware.

Stratosphere: Fix IServer constructors. SM is fully functional on hardware now.

Stratosphere: Implement support for deferred commands. Finish sm GetService()'s deferred path.

Add ExistingPortServer to libstratosphere

Stratosphere: Move boost/callable_traits into libstratosphere

Stratosphere: ServiceServer<T> -> IServer<T> as abstract base class.

IPC templating style fix

Stratosphere: extract common code to libstratosphere.
