227cc19890 add alpha version of x64 support 
New features:
- support of kernel tasks in 64bit mode
- support of LwIP in 64bit mode

Missing features in 64bit mode
- user-level support
- APIC support => SMP support

To create a 64bit version of the MetalSVM kernel, the compiler flags “-m64 -mno-red-zone” and the assembler flags “-felf64” has to be used. Please use qemu-system-x86_64 as test platform.

Notice, metalsvm.elf is a 32bit ELF file. However, it contains (beside the startup code) only 64bit code. This is required because GRUB doesn’t boot 64bit ELF kernels. Therefore, for disassembling via objdump the flag  “-M x86-64” has to be used.

7b63bf1d27 !!!!! -> increasing the offset has to be done inside the fs/chardriver. 
- rewrite the initrd_read/write, char_driver r/w. Now all functions use fildes_t instead of vfs_node_t structs.
- eleminate some compiler warnings
- some changes in open, to reduce compiler warnings. This function isn't working yet!

3d74f1b514 - rewrite the read_fs and write_fs. Now both functions use fildes_t instead of vfs_node_t structs. 
INFO:	typedef struct fildes {
        	vfs_node_t* 	node;
        	off_t 		offset;
		int 		flags;
		int 		mode;

- merge fs_types.h and fs.h into one file fs.h
