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.

a0b9a635ca Fix Killing Guest Processes in KThread::Kill and fix TID/PID naming
This commit mainly fixes the problem with process leakage before where the guest process wouldn't be killed. In addition, it clears up the problem with naming differences with PID/TID where purely PID was used before but that term is generally used to refer to the PGID. So, `KProcess` has a `pid` member but `KThread` has a `tid` member.

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.

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:

694c8ef4e2 Addition of Conditional Variables
This commit adds working conditional variables, in addition to the mutex and threading implementation. It directly depends on the memory optimization from the previous commit to be able to perform atomic operations on the mutex.

03b65bd90a Optimize Memory Implementation using Shared Memory
This commit further improves the memory implementation by using shared memory for all allocations so we won't have to depend on a kernel call for doing any host <-> guest memory transfers.

d02267c34f Add support for threads and mutexes
This commit adds support for threading and mutexes. However, there is also a basis of conditional variables but these don't work due to the lack of a shared memory model between the guest and host. So, conditional variables will be deferred to after the shared memory model is in place.

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.

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.
