lephe 705854da39 getkey: exclude other keys during a repetition 
When a key is being held and repeated, ignore other key presses
until it is released. Without this, new keys would take priority.

This is the desired behavior because pressing other keys by
accident, especially on the directional pad, is common. Besdeis
this is the system's behavior.

lephe 1697998a9c tmu: improve code style and clear masks 
Apparently there are some situations where the interrupt masks for
TMU0 are set in the system. They should obviously be cleared.

lephe 1685813078 libc: fix a pointer overflow in kprint 
When the size of the input buffer is not specified, the default was
INT_MAX; however this will cause the pointer value to overflow in many
situations, causing kprint_flush() to flush prematurely and write NUL
bytes at inappropriate places.

This commit changes the default size to 65535. Morale: never use
sprintf() or vsprintf()...

lephe 2d7a6f154e libc: implement a compliant formatted printer 
This is based on a port of kprint, which supports standard formats and
options, except for:

* Large parameters (ll)
* Floating-point types (%e, %E, %f, %F, %g, %G, %a, %A)

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 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 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
