QCDLZCLW3K f8a09580ea Support pop'n music 15-18
* popnhook1 for pop'n 15 - 18 has been added
* popnio has been added
* inject.exe has new syntax for loading hook DLLs, `real.dll=hook.dll`. This will trigger an early IAT hook where it will load the EXE suspended without resolving imports, replace the reference to real.dll in the import table with hook.dll, and then resolve everything before launching. This allows for ezusb.dll to be hooked properly.
* launcher.exe also has a new early IAT hook feature now. Use `-I real.dll=hook.dll`. The idea is the same as described above for inject.exe.
* Updated ezusb constant namings based on what is visible in ezusb.dll's debug statements.

The launcher.exe implementation of early IAT hooking means that someone can implement popnhook2.dll for 19 and above. I have tried pop'n music Sunny Park using a modified version of popnhook1 and it seems to work to some degree: the I/O check and security check returns OK which means the ezusb hooking used in popnhook1 is also working for the later games using `launcher.exe -I ezusb.dll=ezusb2-popn-shim.dll ...`. The process is rather invasive (manually resolving all imports means more chances to fail) so it has been implemented in such a way that the launcher will work the same as it has before as long as `-I` isn't specified.

One questionable thing I am not confident about is the `texture_usage_fix` hack flag I added in the conf. As the comment says, pop'n music 16 will work in Windows XP without the flag being set, but the game will immediately crash on later OSes without the flag being set in my experience. No other games had this issue in my experience. Enabling it in other games doesn't seem to have any negative effects.
