668f623256 Implement Exceptional Signal Handler + Fix Destruction Behavior
An exceptional signal handler allows us to convert an OS signal into a C++ exception, this allows us to alleviate a lot of crashes that would otherwise occur from signals being thrown during execution of games and be able to handle them gracefully.

Initial Savedata Implementation (#75)
* Rework VFS to support creating and writing files and introduce OsFileSystem
OsFileSystem abstracts a directory on the device using the filesystem API.
This also introduces GetEntryType and changes FileExists to use it.

* Implement the Horizon FileSystem APIs using our VFS framework
Horizon provides access to files through its IFileSystem class, we can
closely map this to our vfs::FileSystem class.

* Add support for creating application savedata
This implements basic savedata creation using the OsFileSystem API. The
data is stored in Skyline's private directory is stored in the same
format as yuzu.

dca06f2b49 Rework loader abstractions and the NRO loader to use the vfs APIs
This will make it easier for us to implement more executable formats in
the future.

c76ef3730b Move to MPL-2.0
We earlier moved to LGPLv3.0 or Later. This was a mistake as what we wanted was being able to link to proprietary libraries but LGPL is the opposite and it allows linking proprietary libraries to libskyline instead. After further consideration, we've moved to MPL-2.0, it allows linking to proprietary libraries and is a standardized license as compared to adding an exception to GPL.

c37f350c02 Move from GPLv3 to LGPLv3 or later
Skyline has been licensed with GPLv3 but as we want to look into optional ads in the future, and that would require linking AdMob SDKs which are proprietary. So, we decided to move to LGPLv3 so we could keep that option open as a revenue stream. 

We've gathered consent from all contributors for the license change:

00cdc1fd6f Refactor the memory implementation and add Regions
This commit does a major refactor of the memory implementation, it forms a memory map which is far cleaner than trying to access it through a handle table lookup. In addition, it creates a common interface for all memory kernel objects: KMemory from which all other kernel memory objects inherit. This allows doing resizing, permission change, etc without casting to the base memory type.

493a1a93ec Use .clang-tidy and remove madvise DO_FORK/DONT_FORK calls
This commit causes Android Studio to use the .clang-tidy file for configuration and removes madvise DO_FORK/DONT_FORK calls as they cause problems on many devices and are mostly unnecessary.

65018aedbc Complete making the kernel thread-safe #2 + Fix Shared Memory Implementation
This commit makes the kernel completely thread-safe and fixes an issue that caused libNX games to not work due to an error with KSharedMemory. In addition, implement GroupMutex to allow the kernel threads to run in parallel but still allow them to not overlap with the JNI thread.

970dde8c27 Move from ptrace to junction branching and make kernel multithreaded
This commit is a huge step in the direction of better performance, as we move from ptrace to junction branching and have kernel call overhead similar to that of a native kernel call! In addition, this sets the base for the kernel to go fully multi-threaded. However, the kernel is currently not thread-safe and therefore this commit currently causes a crash.

b84859d352 Remove support for multiple guest processes
This commit removes support for more than one guest processes as it requires a fair bit of extra code to support in addition the HLE service implementations don't support it anyway.

b3e811d488 Adapt C++ backend to changes
This commit adapts the C++ backend to the Kotlin frontend by moving to usage of file descriptors and, provides an interface to access frontend code via JNI which is used to check the state of the activity and catch events such as surface destruction. In addition, this commit fixes some minor linting errors and changes the CMake version to 3.10.2+.
