Feature Dynamic Recompiler support and sync to SVN r4301

[retro100]

I synced the dosbox-wii version to Revision r4301 and also apply the patches from jmarsh for dynamic recompiler support. See: https://www.vogons.org/viewtopic.php?t=65057

I create a description for compilation (INSTALL_Wii.md). If I compile the this version with the latest devkitPro version like descripted in INSTALL_Wii.md ~~then I can't use the virtual keyboard. Using the virtual keyboard results in a dump (Exception (DSI) occurred!).~~ edit: Bug is now fixed ;-)

The sync to r4301 and the jmarsh patches are not the problem ~~because the virtual keyboard bug also happends at 328bcd9 which only contains small changes for successful compilation.~~

@dborth: Maybe you can fix this bug. I havn't a USB Gecko for debugging. And didn't try debugging with Dolphin emulator. For me it would also be a big help if dosbox-wii version 1.7 compiles with the current doskitPro version without the virtual keyboard bug.

For the compilation I can't use the current package version for SDL from devkitPro. I have to compile and install the version from your repo. The reason is described in INSTALL_Wii.md. It would be fine if the SDL version from devkitPro can be used. ~~The file src/platform/wii/globals.cpp is also needed for compiling with the new lib versions. Because some variables are not exported by the versions from devkitPro (resulting in undefined reference linking errors).~~ edit: The fixed version now uses the auto generated headerfiles from bin2o (bin2s) in filelist.h

~~If you want to compile this current dosbox version with the old devkitPro and libs which used for Dosbox 1.7 then LIBS_VER can be set to OLD inside the Makefile. I don't know which devkitPro version and which library versions are used for Dosbox 1.7. So I don't have test it to compile with old devkitPro and libs versions.~~ edit: Only the current devkitPro version is supported

For testing this current version with dynamic recompiler support ~~and the virtual keyboard bug~~ a pre-release from https://github.com/retro100/dosbox-wii/releases can be downloaded. This is compiled like descripted in INSTALL_Wii.md.

The file docs/Benchmark_Wii_WiiU.txt includes some benchmarks with and without using the dynamic recompiler. The file docs/PORTING_Wii.txt includes a short list of files which are modified files compared against the original svn repository (revision 4301). These modifications are applied from the current Dosbox 1.7 version.

I am grateful for any help ~~to fix the virtual keyboard bug.~~

Best regards retro100

The keyboard bug is removed ;-) There was also another bug. The wiimote havn't work. The reason was because the button states wasn't updated. ~~On new libogc version WPAD_ButtonsHeld(i); doesn't automatic update the button states. It is absolutely necessary to call WPAD_ScanPads() to update the joystick states (which wasn't the case).~~ edit: The problem was that SDL_JoystickUpdate() was not called because of the SDL_GetTicks() bug. See: https://github.com/retro100/dosbox-wii/issues/4

Now the menu and the virtual keyboard can be used. The current version with sync to SVN r4301 and Dynamic Recompiler support is ready. A compiled version (pre-release) can be found at ~~https://github.com/retro100/dosbox-wii/releases/tag/1.7x.beta2~~ new: https://github.com/retro100/dosbox-wii/releases/tag/1.7x.beta4

~~I think its time to release a official DOSBox Wii version ;-) Maybe 1.8?~~

~~Unfortunately, there is another very strange bug :-( See https://github.com/retro100/dosbox-wii/issues/4~~
