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.

* Move cache to own struct
* Encapsulate retrieving entries a bit

This enables Rockbox to render anti-aliased fonts using an alpha blending method.
The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same.
A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided.
It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).

* Remove THREAD_ID_CURRENT macro in favor of a thread_self() function, this allows thread functions to be simpler.
* thread_self_entry() shortcut for kernel.c.

* Add backlight_force_on() which forces to turn on backlight even when the setting is set to Off. use this in lamp.
No functional change except lamp.

* Allow skip-to-beginning in single-play mode; there is no 3-second delay in that case.
* Properly handle and keep track of pauses caused by headphone removal.
* Improve skipping over bad files - search in skip direction and allow it to be ended with the stop key.
* Add the system message processing done elsewhere to all button queue waits.

Add mode to play multiple mpeg files in the same directory in the order the file browser shows.
In this mode, Mpegplayer exits after finishing the last .mpg file.

Move to plugin_crt0.c, plugins don't need PLUGIN_IRAM_* macros anymore
IRAM is no longered zeroed before copying (as it is at the same address
than BSS) -> Fix FS#11581
Use cpucache_invalidate() (and not cpucache_flush), needed for self-modifying code on cached IRAM

It handles exit() properly, calling the handler also when the plugin returns
normally (also make exit() more standard compliant while at it).
It also holds PLUGIN_HEADER, so that it doesn't need to be in each plugin anymore.
To work better together with callbacks passed to rb->default_event_handler_ex() introduce exit_on_usb() which will call the exit handler before showing the usb screen and exit() after it.
In most cases rb->default_event_handler_ex() was passed a callback which was manually called at all other return points. This can now be done via atexit().
In future plugin_crt0.c could also handle clearing bss, initializing iram and more.

Modify HIGH_REGS macro to store/load only one range of registers
When the range isn't contigous (in MC_put_x_8*), shift registers to make
it contigous (r4 and r5 are now unused by these functions)

We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734
