Summary:
- The wav header parser in /dev/audio/pcm device driver expects the 'data'
chunk is placed just after the 'fmt ' chunk.
- Because the wav files generated by FFmpeg places 'LIST' chunk which
contains the music track information between 'fmt ' and 'data' chunks,
nxplayer cannot playback the files.
- This patch skips extra chunks after 'fmt ' chunk to find the 'data' chunk.
Impact:
- All architectures which support /dev/audio/pcm device.
Testing:
- Tested by Raspberry Pi Pico audio driver.
- nxplayer can playback the wav files which are created by FFmpeg after
applying this patch.

Make.dep file should be updated by .config changed after first make.
There are 2 cases affected for this problem:
1) Add source files by config symbol
2) Include header files in #ifdef directive
These 2 cases may not be included in Make.dep and this may prevent the
differential build from working correctly.
This change is needed to be able to fix the warnings on the audio core
and includes the propagation of the fix in the audio.

This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

Fixed coding standard error in several files. Use of while( is incorrect; a space is required between while and (. Also ran tools/nxstyle and fix thoses complaints as well in most files.
Changes to comply with coding standard. Mostly focused on files with missing space after keyword in if(, switch(, and for(. Offending files also got changes to comply with tools nxstyle. If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh. Still need to fix occurrences of while( with missing space. There are a lot of them.
