◱ PixelyIon 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.

◱ PixelyIon 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:

◱ PixelyIon 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.

◱ PixelyIon 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.

◱ PixelyIon de6d8d8f48 Work on making the kernel thread-safe #1 + add asynchronous ROM scanning 
This commit makes the kernel thread safe in some instances (but not fully) and showcases the significantly improved performance over the ptrace method used prior. In addition, scanning for ROMs is now done asynchronously.

◱ PixelyIon 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.

◱ PixelyIon 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.

◱ PixelyIon 3e9bfaec0e Introduce Basic Junction Patching
