adba0ce80b fix g_dfu access from both DFU and runtime access
We need to refer to g_dfu as a pointer from all code.  In DFU mode, it
gets assigned to the address of _g_dfu, which is placed by the linker
script at the start of RAM.  In runtime mode, the pointer is statically
defined to point at the start of RAM.  The linker script for the runtime
(dfu environment) is adjusted to save the first 32 bytes for the _g_dfu
structure.

32852bc1d9 DFU: towards a more complete implementation
* we now actually route the EP0 control requests in DFU mode to the
  correct handler (weak linker symbols are tricky)
* we now actually call code to read/write data from/to RAM/FLASH

3f5e3ddffc Change directory structure to align with Atmel softpack
This way we can easily check with 'diff' for differences in our code and
Atmel softpack.  Also, this layout is more suitable for building various
different firmware images (e.g. factory-test, dfu-loader, main
application) for a variety of different boards (simtrace, owhw, qmod).
