Timo Kreuzer 9efafd640f [CRT] Import wine exception handling code
The code is mostly unchanged. This includes the following changes:
* Move all wine code to crt/wine to keep it separated from our own code
* Add a minimal winternl.h
* Remove the asm macros from wine/config.h
* Include wine/asm.h where required
* Fix the names of the exported functions (GCC uses thiscall now and no wrappers are used anymore)
