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.

The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.
This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.
See buflib.h for some API documentation.

Namely, introduce buffer_get_buffer() and buffer_release_buffer().
buffer_get_buffer() aquires all available and grabs a lock, attempting to
call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause
a panicf() (doesn't actually happen, but is for debugging purpose).
buffer_release_buffer() unlocks that lock and can additionally increment the
audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was
used temporarily only.
buffer_available() is a replacement function to query audiobuflen, i.e. what's
left in the buffer.
Buffer init is moved up in the init chain and handles ipodvideo64mb internally.
Further changes happened to mp3data.c and talk.c as to not call the above API
functions, but get the buffer from callers. The caller is the audio system
which has the buffer lock while mp3data.c and talk mess with the buffer.
mpeg.c now implements some buffer related functions of playback.h, especially
audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit.
audiobuf and audiobufend are local to buffer.c now.

I tried to move the #ifdefs and the code
in firmware/powermgmt.c around and it was still
a big mess for hosted applications (RaaA/sim builds).
Create our own "power" thread as recently discussed on IRC.
Fixes the sleep timer for RaaA.

* Re-create RockboxFramebuffer instance with every time there's a new Activity.
* Also, allow Rockbox to be started via multimedia buttons, immediately starting playback if wanted.
We don't need to keep the fb instance around when it backround, and it makes us less depending on it and the activity (less race conditions). And this is how you usually do it in Android apps.

The notification now announces the new track on track change, and the the area in the scrolled down notification area shows track infos (title, artist, album).
Someone should check if it looks good on hdpi and ldpi screens as I can't verify it right now (emulator crashes).

Skins are now more self contained in the skin manager which in the future might allow on demand skin loading (i.e smaller skin buffers)
Skin backdrops are also managed more intelegently (fixes a bug where you can get a crazy backdrop loaded if a .sbs fails to load)
the rockbox_default rescue theme is now called rockbox_failsafe to better express what it actually is.
This commit hopefully/maybe fixes the heavily reported data aborts, so please check if you are getting them

Since memory on 32mb ipod videos is mapped twice, a 64mb build still has codecs and plugins mapped in a usable area. This means that all that needs to be done to support 32mb and 64mb boards with the same build is to adjust audiobufend to avoid using more than the actually present RAM.
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27960 a1c6a512-1295-4272-9138-f99709370657
For RaaA it evaluates user paths at runtime. For everything but codecs/plugins it will give the path under $HOME/.config/rockbox.org if write access is needed or if the file/folder in question exists there (otherwise it gives /usr/local/share/rockbox).
This allows for installing themes under $HOME as well as having config.cfg and other important files there while installing the application (and default themes) under /usr/local.
On the DAPs it's a no-op, returing /.rockbox directly.
Not converted to use get_user_file_path() are plugins themselves, because RaaA doesn't build plugins yet.

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.

It's now easier to force rebuild of files depending on the svn revision
version.c/version.h are generated once with new tools/genversion.sh
Changes in the VCS are still not auto detected, so you'll have to remove
builddir/version.* if you want to change the string in your binaries
APPSVERSION is now called RBVERSION and is defined in the generated
header instead of being defined by the Makefiles
appsversion is now called rbversion (the plugin api number didn't change
since old modules are still binary compatible)
Change some bootloaders to use knwon-at-buildtime RBVERSION instead of
"%s" + rbversion
You'll need to run make clean to regenerate dependencies after the
removal of apps/version.h
To build binaries with a different version string, hand-edit
tools/version.sh or tools/genversion.sh (which calls the former)

- Refactor the program startup. main() is now in main.c like on target, and the implicit application thread will now act as our main thread (previously a separate one was created for this in thread initialization).
This is part of Rockbox as an application and is the first step to make an application port from the uisimulator. In a further step the sim bits from the sdl build will be separated out.

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.

Select (B)ootchart in advanced options in configure, and logf will record timings for various stages of boot, for performance comparisons. Format logged is:
BC:>function_name,123,80
where 123 is the line number, 80 is the number of ticks since boot. This can be loaded as CSV into a spreadsheet.

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.

What this also does is remove a bunch of unnecessary settings_Apply()'s from the ipod accessory code, and causes all non-skin settings to get applied each time (this includes font and langs which we wernt doing to stop disk access)

Hopefully the only user visible changes are:
- fm and recording screens go by the statusbar setting (sbs or inbuilt)
- plugins go back to using the theme as they should for menus and lists
- splash screens might get cut a bit... entirely theme and splash dependant.. if there is a problematic one we can look at it later.
- hopefully nothing more than very minor screen flickerings... let me know exactly where they are so they can be fixed
New GUI screen rules:
* Screens assume that the theme (sbs+ui viewport+ maybe background image) are always enabled. They may be disabled on a per display basis, but MUST be re-enabled on exit
* Screens must not be coded in a way that requires a statusbar of any type.. the inbuilt bar will be removed shortly.
ALWAYS RESPECT THE USERS SETTINGS unless the screen requires the full display to fit.

Now, call it earlier and remove parts of it that caused the need to call it later. Removing that is OK since it's done again on settings loading.

Since it can't return, app_main() can't either, tell gcc about it.
Remove dead archos code (present if root_menu() would return
erroneously), and rename app_main() to main() on target

This fix is as good as we can do, but not perfect. Because the sbs is only updated when a button is pressed it will stay in the "volume changing" state probalby longer than expected.. which isnt terrible, but useful to remember.

The custom statusbar can be used as a WPS for the main UI, using .(r)sbs files. It's using the skin engine and knows all tags the WPS also knows.
The default folder for .sbs is the wps folder to reuse images used in the WPS.
As it can be shown in the WPS also, it's useful to move shared parts to the custom statusbar in order to save skin buffer space.
There are a few restrictions/TODOs:
*) Peak meter doesn't redraw nicely(not frequent enough), as very frequent updates would slow the UI down as hell (some targets fight with it in the WPS already: FS#10686)
*) No touchregion support as the statusbar doesn't have any action handling (it won't fail to parse though).
*) Drawing stuff into the default VP is forbidden (loading images in it is not). You *need* to use viewports for the displaying stuff (parsing fails if no viewport is used).
*) Themes that don't use a custom ui viewport can be fixed up using the new %Vi tag to avoid nasty redraw effectts (you must not draw into it as well, it's used to fix up the ui viewport). %Vi describes the viewport that the lists can use without getting in the way of the statusbar.
Otherwise, it behaves like the classic statusbar, it can be configured in the theme settings, and can be turned off in the wps using %wd.
Note to translaters: When translating LANG_STATUSBAR_CUSTOM, please consider using the same translation as for LANG_CHANNEL_CUSTOM if it's compatible. They could be combined later then.
