Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then.

The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback.

This new implementation is based off reverse-engineering of the real kernel.

See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

Remove unused version.h in citra_qt

Move WINVER definition to cmake and a bit of cleanup

dynarmic: Fix ABI violation

Caused by not saving/restoring the x64 r15 register on entry/exit from
JITted code.

Closes #2224.

ClangFormat: Fixed the clang-format errors

Set client SDK version to Service APIs

Build: Fixed a few warnings.

Kernel/Loader: Grab the system mode from the NCCH ExHeader.

Remove the broken frame_skip option

Correct FS error codes & add path boundary checks

3dsx and elf files default to system mode 2 (96MB allocated to the application).

This allows Home Menu to boot without modifications.
Closes #1849

Rasterizer/Memfill: Set the correct stencil write mask when clearing the stencil buffer.

Fixes #1960.

MIC_U: Stub service funcions

Change "user" folder default location to AppData/Roaming/ on Windows systems

dynarmic: Add ticks based on ticks executed, not ticks requested

Expose page table to dynarmic for optimized reads and writes to the JIT

Travis: Remove build uploading

@archshift has been MIA for a while, so our builds server is currently
down. Furthermore, uploading is broken in both Linux and macOS:

- The version of lftp in Trusty doesn't support the sftp:auto-confirm
  option, which means that uploading would hang, even if the server
  weren't down. It currently tries to connect forever and fails the
  build with a timeout.
- lftp was removed from Homebrew, so it wasn't being installed on macOS
  and invoking it just failed.

Windows, move to SDL2-2.0.5

This patch brings +3% performance improvement on average. It removes
ToVertex() as an important hotspot of the emulator.
