Merge Wine shell32 commit:

Francois Gouget <fgouget@free.fr>
Cleanup the handling of the extension in SHELL_FindExecutable():
- Eliminate the corresponding fixed-size buffer which removes the limitation to 3 character extensions.
- Fix handling of the trailing '.' case.
- Do a case-insensitive check for the extension in win.ini.
  Increase the size of the command buffer to 1024.
