Thomas Jarosch c55be3b83a maemo port: Fix startup crash exposed by audio thread refactoring 
The refactoring of the audio thread in this commit
-----------------------------------------------
commit 5857c44017
Author: Michael Sevakis <jethead71@rockbox.org>
Date:   Fri May 31 02:41:02 2013 -0400

    Refactor audio thread to run both recording and playback.
-----------------------------------------------

moved pcm_init() next to dsp_init() in apps/main.c:init().
Before that pcm_init() was called by audio_init().

Unfortunately the maemo init code didn't properly
wait until the maemo thread was fully initialized,
leading to dangling pointers when the code called
by pcm_init() tried to access maemo's variables.

Fix it by refactoring the "very fast shutdown" semaphore
to wait until maemo is initialized in any case.

This should also fix very rare rockbox crashes
on startup that I got once a year or so.
The new code has been tested by a script that
starts and kills rockbox after one second.

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.bz2

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 sh/arm/m68k-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 acquired with the rockboxdev.sh script in the /tools/ folder of the
   source, or will have been included if you've installed one of the
   toolchains or development environments provided at http://www.rockbox.org/

   $ which sh-elf-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-fmrecorder
   $ cd build-fmrecorder
   $ ../tools/configure

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