Simple sd card driver (#162)

Browse Source 
* fixed inline functions for modern C standart

* more stack for application

* added library

* init fatfs library

* fatfs example application

* Merge with current master

* fix typo and delete old files

* cmsis os 2 reentrance fix

* Reworked dependency wait to support multiple dependency

* Build FatFS on local target, syscall.c is target-specific.

* run local target ok
