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

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: Implement basic passthrough framework for input commands.

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

loader, pm, sm: build kip as only taget (thanks @fincs !)

Fix the remaining warnings in stratosphère

Merge pull request #84 from leoetlino/printf-format ...

ldr: Fix printf format string for size_t

Exosphere: Add API for retrieving versioning info.

Loader: Fix char * const correctness.

Loader: Fix game update content loading, fix SD card mounting on newer firmwares. Closes #61.

Fix minor bugs in loader/sm

ldr: Fix printf format string for size_t ...

%z should be used for size_t, otherwise the wrong value may be printed.

Fixes two -Wformat warnings.

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.

Stratosphère: Simplify some for loops (#76) ...

Simplifies some loops by removing the need to manually calculate or
re-specify the array size. Eliminates any chance of using the
wrong size and less typing.

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

Loader: Fix (all?) remaining bugs in ldr:pm. ...

Loader now works when booted as a KIP1. NOTE: ldr:ro still needs
debugging.

Loader: Finish ldr:ro

Loader: Add ldr:ro->LoadNro()

Loader: fix missing NULL assignment

Loader: Automatically unload NRRs on service close.

Loader: Implement ldr:ro->UnloadNrr()

Loader: Implement ldr:ro->LoadNRR(). NOTE: No sigchecks, at the moment.

Loader: fix missing reassignment in AutoCloseMap

Loader: Start work on LoadNRR, Add AutoCloseMap

Loader: Greatly simplify mapping logic, add CodeMemory mapper.

Loader: Add NRRInfo to RegisteredProcess, refactor Registration::

Loader: Service ldr:ro on <= 2.3.0

Loader: Implement ldr:ro->Initialize()

Loader: Push ldr:ro stub.
