◱ 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 7f78a679c3 Add Performance Statistics to `EmulationActivity`
This commit adds performance statistics to the emulator that can be toggled in preferences. The layout of `EmulationActivity` was also changed from `ConstraintLayout` to `RelativeLayout` due to poor performance of the former.

◱ PixelyIon af98455ede Add Mutexes to Logger, Introduce `util::MakeMagic` and Refactor IPC
This commit adds mutexes to the logger so they produce a valid log file rather than breaking due to a race condition. It also introduced `util::MakeMagic` so the magic functions are far more clear. A small refactor of IPC was also done which cleared up some of the for loops.

◱ 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 42d982c6fb Refactor Display Services and GPU
This commit addresses the incorrect hierarchy of the GPU and refactors them at the same time. Now, the hierarchy much closely matches HOS. This commit also introduces a texture classes, albeit they're not complete and only partially implemented.

◱ PixelyIon 08bbc66b09 Fix CR issues and Game Duplication + Move to Vector for Memory Map
This commit fixed the issues outlined in the CR (Mainly correlated to formatting), moves to a sorted vector from a sorted list for the memory map in addition to using binary search for sorting through rather than iteratively and fixes item duplication in the game list when directory is changed in Settings.

◱ PixelyIon 66d20a9429 Fix GroupMutex and Clock Rescaling
This commit mainly fixes GroupMutex and clock rescaling. In addition, clock rescaling is no longer performed if the CNTFRQ_EL0 of the host device is same as that of the Switch (19.2MHz) which is fairly common on higher end devices.

◱ 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 48d47a2b25 Move from dependency on JNI and Implement AtomicMutex
This commit is the start of moving towards a lockless and faster kernel which can run multiple independent threads with fast userspace synchronization.

◱ PixelyIon c5dce22a8c Fix JNI Race Condition, Fix Release Builds and Fix Searching
This commit fixes JNI race conditions by usage of a mutex, fixes a bug in release builds due to ProGuard member obfuscation and fix searching by fixing the HeaderAdapter filter.

◱ PixelyIon 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+.

◱ PixelyIon 38716989ae Improve IPC interface
This commit changes how IPC is interacted with in two ways:
* Simplify all buffers into just InputBuffer and OutputBuffer
* Use pushing/popping for data payload

◱ PixelyIon 745cb208a6 Optimize deswizzling implementation and support multiple formats
The deswizzling implementation currently writes linearly and reads non-linearly, this is non optimal as the MMU cannot read ahead. This flips that and reads linearly while it writes non-linearly. This is based on: 324a3624ac/nx/source/display/framebuffer.c (L189).
