Initial support for scripting (#4016) * Add ZeroMQ external submodule * ZeroMQ libzmq building on macOS * Added RPC namespace, settings and logging * Added request queue handling and new classes * Add C++ interface to ZeroMQ * Added start of ZeroMQ RPC Server implementation. * Request construction and callback request handling * Read and write memory implementation * Add ID to request format and send reply * Add RPC setting to macOS UI * Fixed initialization order bug and added exception handling * Working read-write through Python * Update CMakeLists for libzmq to resolve target name conflict on Windows * Platform-specific CMake definitions for Windows/non-Windows * Add comments * Revert "Add RPC setting to macOS UI" * Always run RPC server instead of configurable * Add Python scripting example. Updated .gitignore * Rename member variables to remove trailing underscore * Finally got libzmq external project building on macOS * Add missing dependency during libzmq build * Adding more missing dependencies [skip ci] * Only build what is required from libzmq * Extra length checks on client input * Call InvalidateCacheRange after memory write * Revert MinGW change. Fix clang-format. Improve error handling in request/reply. Allow any length of data read/write in Python. * Re-organized RPC static global state into a proper class. [skip ci] * Make sure libzmq always builds in Release mode * Renamed Request to Packet since Request and Reply are the same thing * Moved request fulfillment out of Packet and into RPCServer * Change request thread from sleep to condition variable * Remove non-blocking polling from ZMQ server code. Receive now blocks and terminates properly without sleeping. This change significantly improves script speed. * Move scripting files to dist/ instead of src/ * C++ code review changes for jroweboy [skip ci] * Python code review changes for jroweboy [skip ci] * Add docstrings and tests to citra.py [skip ci] * Add host OS check for libzmq build * Revert "Add host OS check for libzmq build" * Fixed a hang when emulation is stopped and restarted due to improper destruction order of ZMQ objects [skip ci] * Add scripting directory to archive packaging [skip ci] * Specify C/CXX compiler variables on MinGW build * Only specify compiler on Linux mingw * Use gcc and g++ on Windows mingw * Specify generator for mingw * Don't specify toolchain on windows mingw * Changed citra.py to support Python 3 instead of Python 2 * Fix bug where RPC wouldn't restart after Stop/Start emulation * Added copyright to headers and reorganized includes and forward declarations
