Christian Soffke 8eefac3638 quickscreen: prevent out-of-bounds viewports
Fixes possible crash in case of pathological
UI vp dimensions, when attempting to clear a
QS item's vp.

E.g. https://github.com/federicoplg/musicOS
(commit c5e8570) configures a 1x1 UI viewport
at x=319 y=239, resulting in left/right item
viewports that have negative width or height.

Minor additional simplifications with no
effect on behavior:

- Combine actions requiring cleanup in a setup function.
  Put it below the existing cleanup function
- Rename quick_screen_quick to quickscreen_show, and
  quickscreen_run to quickscreen_main
- Iterate over items using FOR_QS_ITEMS macro
- Remove quickscreen_draw_item's int_value
- quickscreen_update: immediately continue if qs skinned
- Remove some obsolete #includes

Build Your Own Rockbox

1. Clone 'rockbox' from git (or extract a downloaded archive).

   $ git clone git://git.rockbox.org/rockbox

     or

   $ tar xJf rockbox.tar.xz

2. Create a build directory, preferably in the same directory as the firmware/
   and apps/ directories. This is where all generated files will be written.

   $ cd rockbox
   $ mkdir build
   $ cd build

3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
   that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
   a particular version depending on what player you are compiling for. These
   can be generated using the rockboxdev.sh script in the /tools/ folder of the
   source.

   $ which arm-elf-eabi-gcc
   $ which perl

4. In your build directory, run the 'tools/configure' script and enter what
   target you want to build for and if you want a debug version or not (and a
   few more questions). It'll prompt you. The debug version is for making a
   gdb version out of it. It is only useful if you run gdb towards your target
   Archos.

   $ ../tools/configure

5. *ploink*. Now you have got a Makefile generated for you.

6. Run 'make' and soon the necessary pieces from the firmware and the apps
   directories have been compiled, linked and scrambled for you.

   $ make
   $ make zip

7. unzip the rockbox.zip on your music player, reboot it and
   *smile*.

If you want to build for more than one target, just create several build
directories and create a setup for each target:

   $ mkdir build-fuzeplus
   $ cd build-fuzeplus
   $ ../tools/configure

   $ mkdir build-xduoox3
   $ cd build-xduoox3
   $ ../tools/configure
