fe5061a8e0 Address CR Comments (#132) + Change Core Migration API
This addresses all CR comments including more codebase-wide changes arising from certain review comments like proper usage of its/it's and consistent contraction of it is into it's. 

An overhaul was made to the presentation and formatting of `KThread.h` and `LoadBalance` works has been superseded by `GetOptimalCoreForThread` which can be used alongside `InsertThread` or `MigrateToCore`. It makes the API far more atomic and neater. This was a major point of contention for the design prior, it's simplified some code and potentially improved performance.

a621408b9c Move to using ASCII separators for Logger
We've moved to using RS and GS from ASCII as delimiters rather than
'\n' and '|', this allows more robust parsing and increases the
readability of the log files

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.

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.

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:

773ee25e5a Refactor Common
This refactored common by:
* Moving out as many constants to class/function local scopes from being declared in `common`
* Spacing out common and any function to which a constant was moved out to
* Fixing comments here and there
In addition, some naming inconsistencies were fixed as well.

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.

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.

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.

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.

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+.
