Loader: clean up orphaned function prototype

loader/fs.mitm: Support override config changes at runtime

fs.mitm: Use same override button semantics as loader.

atmosphere: extract API version management to common folder

Loader: fix automatic apptype patching.

Loader: Fix HBL pool partition ID copy

Loader: Button override + first-class HBL support

Add and fix copyright notices for better GPL compliance (thanks @naehrwert and @CTCaer).

loader: Add support for 6.0.0.

Stratosphere: use isxdigit to check if char is hex.

Loader: Fix exefs nsp support. Works on hardware.

Loader: Add support for exefs redirection to code nsp on SD.

Loader: Change ips patch location to ease patch distribution

Loader/ips: Fix more bugs, now works with simple test on hw.

Loader/ips: fix compile error

Loader: Fix IPS edge condition, change ips location

Loader: Implement IPS/IPS32 patching.

Loader: Skeleton IPS/IPS32 patching support.

Loader: Support loading FsStorageId_None content from SD.

Stratosphere: Give more memory to SYSTEM, use less memory.

Fix multiple issues reported by Coverity Scan

Loader: Use HW-acceleration for SHA256

stratosphere: In-class initialize members ...

Same thing, less code, less boilerplate.

Loader: Fix argument passing.

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)

Fix the remaining warnings in stratosphère
