4ae87c8b8a Gigabeat: Add timer functionality. Rework tick timer setup to be exactly 100Hz. Metronome should work now but some pcm changes are needed to have faster tocks work correctly (in the works).

7d8c5aaf6a Make backlight fading work again on PP targets. The PP timer cannot handle a (real) cycle count of 1, the minimum is 2. This is now checked in timer_register() and timer_set_period().

bb5fbf7c30 Fix broken backlight fading on ipod. The timer period setting must not be delayed if timer_set_period() is called from within the isr.

cfb073c452 Coldfire: New timer handling on CPU frequency change, adjusting the prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one.

e44372ef18 Moved implementation of user timer to the firmware layer, implemented it for iriver, and made it shareable based on priorities. On iriver, the user timer is shared between the backlight fading and other use, so if a plugin registers the timer, the backlight will resort to simple on/off switching until the plugin releases the timer again. Sorted and bumped the plugin api.
