Patch for tty and some drivers n stuff ;)

[MrSunshine]

tty change dont know if this is the right way, but:
added entries for TIOCM stuff, only stubbed in the tty driver (this is for tcl n stuff later dunno how to implement the stuff tho, hope someone else can do that :P )
added api_version to acpi_thermal and acpi_lid, these drivers are broken tho, mandetory symbol missing and cant find what :)
wchar.h: added missing wcsdup, its implemented but not found in the header file.

the patch

[michaelvoliveira]

add missing wcsdup is needed in order to build FTGL lib

please someone can apply this patch to current build?

[korli]

The wcsdup part is done in hrev34171

Thanks korli!

I suppose the tty stuff didn't miss anyone. I think acpi_thermal and acpi_lid are supposed to be new style api drivers. Sorry for the delay, closing as invalid.
