- make apitest.c into a static lib to be used by different tests

- add a gdi32 api test, based on the one in the win32 folder
- add a user32 api test
- change type of test functions to int
- implement a quick 'n dirty html api status output
- uncomment NtGdiTransormPoints in w32kdll.def
- add ASSERT1 macro (ASSERT is already used)
- include some more headers
