Remove misc. files

- from win32/include/winapi: various .h

  The winapi header set cannot be complete no matter what.  So
  lets have just the minimal set necessary to compile the examples.

- remove CMake support (hard to keep up to date)
- some other files

Also, drop useless changes in win32/lib/(win)crt1.c

win32/lib/crt1.c
