lephe 31ade70c42 tmu: export definitions, clean stop, expose address 
This commit introduces three timer driver changes:

* Export the definitions of the timer structures to a detailed header at
  <gint/mpu/tmu.h>, and re-use them in the driver.
  This integration is still limited as the driver keeps its own address
  definitions and event codes.

* Clean the timer stop routine that is used in the interrupt handler. Up
  until now the interrupt handler would only stop TSTR, which is not
  enough to cleanly leave the timer (need TCOR=TCNT=-1) and is not even
  sound with respect to gint's semantics as UNIE stays enabled so the
  timer is not made available again.

  The interrupt handler now calls into C code when the timer stop
  condition is met (callback returns non-zero) to keep this clean. This
  unsurprisingly solves problems that occurred in certain situations
  when a timer was used repeatedly.

* Expose timer addresses using a timer_address() function, compensating
  for the lack of address definitions in <gint/mpu/tmu.h>. This
  interface is likely to evolve in the future to better integrate the
  address in the MPU headers and move them out of the driver.

lephe 24fbeab55b core: provide MPU type on unknown platforms 
This makes it possible to write application code without specifying the
target machine, which is especially useful for libraries. The first user
of this system is libprof.

lephe d9c32b2b05 libc: split standard headers properly 
Since Memallox's newlib port is currently unstable, gint has to
provide some standard functions on its own. Instead of a single
<gint/std.h> header, this commit makes a gint/std directory containing
headers under standard names.

lephe 04231ea5d6 dma: add a new driver to support r61524 
Also add a power interface (without driving code) and switch toolchain

FPU-free.

lephe f33cb3cf80 core: better bootlog API and implementation 
* Now uses topti instead of fxlib for text (including MMU failure)
* Fit .pretext into 4k for everything before MMU succeeds
* A short version of sprintf() for dynamic messages
* Support a driver function, status(), to allow early driver debug
* Expose more useful platform information in <gint/mpu.h>
* Expose the first of a few CASIOWIN syscalls
