IPC: Don't create unnecessary ports when returning sub interfaces.

 AppletOE: Stubbed CreateManagedDisplayLayer to create a new layer in the default display.

Stub OpenAudioOut and fix a issue with HID IAppletResource

This function is used by libnx to obtain a new layer.

It'll be needed when we implement CreateManagedDisplayLayer.

It is now created during Service initialization and passed to all the services that need it.

VI: Move BufferQueue and NVFlinger to their own folder/namespace.

* stubs for audout:u, audin:u, audrec:u, audren:u, codecctl and decoding tables with nullptr for future implementations

* fixing the changes requested (remove private, explicit)

 nvmap: Make IoctlCommands an enum class

externals: Update dynarmic

* Added nvmemp, Added /dev/nvhost-ctrl, SetClientPID now stores pid

* used clang-format-3.9 instead

* lowercase pid

* Moved nvmemp handlers to cpp

* Removed unnecessary logging for NvOsGetConfigU32. Cleaned up log and changed to LOG_DEBUG

* using std::arrays instead of c arrays

* nvhost get config now uses std::array completely

* added pid logging back

* updated cmakelist

* missing includes

* added array, removed memcpy

* clang-format6.0

VI: Implement the Query transaction of IHOSBinderDriver, and stubbed some results.

This macro resolves to an empty macro in release builds.

gdbstub: Update registers and sizes for aarch64

Fix minor spelling error in CMakeLists

Unicorn build fixups

This gets gdbstub working at least to the point where clients can
communicate with it.

What works:
- Reading/writing GPRegs
- Reading/writing memory
- Interrupting the emulated program and continuing

What does NOT work:
- Breakpoints. Sizes have been updated to u64, but support will need to be
  added in the interpreter for them to work.
- VRegs. Mostly because my gdb was having issues with 128-bit regs for
  some reason. However, the current u128 representation is a bit
  awkward to use and should probably be updated first.

Some of us do not have any i386 libraries required to build x86-32 universal libraries.

Since we use a custom build of unicorn it doesn't make much sense to look for
the system version, unless the user explicitly wants to override this.
