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.

* Rename stuff to not re-use the term dircache
* Move cache to own struct
* Encapsulate retrieving entries a bit

* 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.

* return proper error code when image is too large.
* check return value of read() properly.
* display progressbar.

* apply slideshow timeout in ask_and_get_audio_buffer() if in slideshow mode.

This unifies jpeg viewer, png viewer, and bmp viewer to one plugin, image viewer, so that you can navigate through different image formats.

it is confusing that same function expects different data type (fb_data or unsigned char) depending on the target.

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.

The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.
Should be no functional change to targets or the simulator.

This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

it might be better to not change the message "loading width x height"?

* changed bmp.c so that it loads bitmap larger than LCD correctly.
* removed bmp entry form inbuilt_filetypes in filetypes.c so that bmp files will be opened with bmp viewer when selected in browser.

* Created new directory, imageviewer/ and moved both jpeg/ and png/ under it.
- this still doesn't merge the two plugins. i.e. both jpeg.rock and png.rock will be made for color targets.
- I'm thinking to merge the two plugins to single image viewer later.
