Subject: Added WinMM driver for windows (#236)

* ADLMIDI2: Fixed an MSVC build
However, it may work glitchy!

* Experimental WinMM MIDI driver

TODO: Make a control panel to configure the driver

* WinMM-DRV: A workaround for older MinGW

* WinMM-DRV: WIP control panel appled / tool

* WinMM-DRV: Better test a driver's work

* WinMM-DRV: More progress on a control panel

* WinMM-DRV: And more progress on this control panel
It's almost completed, I need to make the working setup through a registry.

* WinMM-DRV: Driver is almost ready
However, control panel can't ping a driver to reload settings yet

* WinMM-DRV: Fix the missing volume model setup

* WinMM-DRV: Setup reload on the fly now work!

* WinMM-DRV: Stabilize the thing

* WinMM-DRV: Stabilizing

* WinMM-DRV: Avoid all "setup" in names
to avoid a stupid PCA thing:
https://stackoverflow.com/questions/17660404/how-to-programmatically-disable-program-compatibility-assistant-in-windows-7-and

* A small warning fix at the WOPL module

* WinMM-DRV: Fixed some warnings

* WinMM-DRV: Avoid PCA dialog on the installer

* WiNMM-DRV: Make the linking of pthread being optional
Required to use MinGW-w64 toolchain with the "win32" threading mode

* WinMM-DRV: Receive the MODM_RESET to reset the MIDI state

* WinMM-DRV: Attempt to fix a sound distorsion on song song

* WinMM-Drv: Fixed a build on some older MinGW toolchains

* WinMM-Drv: Fixed default settings not being loaded
