Added make qconfig option to allow testing v4l/dvb menus

From: Mauro Carvalho Chehab <mchehab@infradead.org>

- make qconfig option were added.
- This will generate a menu with v4l/dvb Kconfig menus at the beginning of
  the menus and the kernel menus at the end. Kernel menus shoudn't be touched.
- .config is then generated after quiting.
- Curently, .config is not used by Makefile proccess but it is a good candidate
  to be a replacement of Make.config file. With a good .config file, compilation
  should be faster.
