This enables the ability to allocate (and free) memory dynamically
without fragmentation, through compaction. This means allocations can move
and fragmentation be reduced. Most changes are preparing Rockbox for this,
which many times means adding a move callback which can temporarily disable
movement when the corresponding code is in a critical section.
For now, the audio buffer allocation has a central role, because it's the one
having allocated most. This buffer is able to shrink itself, for which it
needs to stop playback for a very short moment. For this,
audio_buffer_available() returns the size of the audio buffer which can
possibly be used by other allocations because the audio buffer can shrink.
lastfm scrobbling and timestretch can now be toggled at runtime without
requiring a reboot.

Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

runtime data fields are filled like any other fields in the mp3entry struct during the call to get_metadata(); HWCODEC still uses the old callback mechanism

(2) Reduced tagnavi memory consumption.
(3) There was a bug that splash screen counter was counting down when
inserting tracks next. But in fact that might be preferred, so always
count down after successful tagcache query.

the default tagbrowser root menu without modifying the default config.
Increased max items in menu to 64 and improved statusbar title.

browser. Browsing not supported by numeric tags yet, and some features
work currently only when tagcache is loaded in ram.
