Yann MAGNIN 752757e0ef VxKernel 0.6.0-13 : Add keyboard API + update timer API 
@add
<> include/vhex/driver/mpu/sh/sh7305/keysc
  | add internal driver primitives
<> include/vhex/driver/mpu/sh/sh7305/tmu
  | add internal driver primitives
<> include/vhex/keyboard
  | add getkey* (high-level) API
  | add key event API
  | add key status API
  | add keycode information
  | add keyboard driver interface

@update
<> include/vhex/driver
  | add KEYBOARD driver flags
<> include/vhex/keyboard
  | isolate each part of the keyboard module
  | link the keycache part with the driver-provided keycache information
<> src/drivers/mpu/sh/sh7305/keysc
  | use the new keycache API (high-level interrupt handler)
  | update keycache API
  | link the new API in the driver device
<> src/drivers/mpu/sh/sh7305/tmu
  | add timer reservation (WIP)
  | use a "reservation" cache to known which timer is free instead of hardware
  | rename internal functions
<> src/module/display
  | Now, by default, DSTACK_CALL() create a pointer on a dstack_call_t
  | use dsubimage dstack primitive in dimage()

@fix
<> board/fxcg50/fxcg50.ld
  | remove the IL-memory and allow only the X-memory area. This because the
      bootloader uses the IL-memory for DMA transfer and other "low-level"
      routine used by Gint.
      Moreover, I originally try to move each "display-driver" in this place,
      but after some profiling and tests, the dclear()/dupdate() combo went from
      9155us up to 33250us (for many reason). So, I keep this area free, but I
      moved-back from RAM display routines.
<> board/fxcg50/initialize
  | remove "section" copy. This role has been delegated to the bootload (vxBoot)
      because, in the final ELF file generated by GCC, many relocalization
      information for the IL/X memory has been set and the bootloader cannot
      performs general relocalization.
      So, all "special section/memory" displacement has been moved in the
      bootloader and we don't have to worrying about the section copy.
<> src/drivers/mpu/sh/sh7305/tmu
  | fix delay calculation in timer reload primitive
  | disable interruption for profiling timer
<> src/module/dislay/
  | fix shader index used during the dstack_render()
  | fix many errors in dimage() shadow render (WIP)
