wip commit: - added kernel syscall to do our patches and hooks to ker…

…nel code - added hook to BAT setup function - setup an IBAT memory section for our own code for user and kernel code execution. about 7.3 MB of memory available here for our code - reworked many parts of the project structure. the FS, loader and menu are now all in one ELF file and can reference functions between them and the util/string/logging functions - moved all project sections to the new area and added a BSS section (for global variables over all parts of code) - added a proper Makefile with dependencies and many more which now builds a loadiine.elf and a loadiine_dbg.elf (only required for developers) - added hook of kernel function PrepareTitle to change the used cos.xml and app.xml values with our own from the game (this fixes many if not all game starts) - changed FS function patching way to allow re-installation of the FS functions (watch out if you remove a function from the array) - moved FS function patching to start of menu code to avoid a race condition on browser FS usage and IBAT setup - added several util and standart string functions - added automatic cos.xml and app.xml parsing code which are than applied in the kernel to it's struct - added a default data XML struct which is used as fallback if app.xml and cos.xml are not available on the SD card

next is fimport section parsing before release of 4.0
