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.

We want simulators to simulate target code where possible, that includes memory constraints and memory allocation schemes. It also removed the sim's ability to show the theme's ram usage.
Use malloc only in application builds.

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)

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)

Don't scroll text in time_screen(). the lines will be redrawn before scrolling statrs, so they don't scroll anyway.

-add wrappers wps_data_load() and wps_data_init() so that other code doesn't need the structs for that
-change (and rename) gui_sync_wps_uses_albumart() to take points to be filled as parameter to get the AA size of a wps

* rename wps_engine to skin_engine as that was agreed on
* rename music_screen back to wps
* clean up the skin display/update functions a bit
* make skin_data_load setup the hardcoded default if a skin cant be loaded for whatever reason instead of doing it when it is first displayed
ignore any gui_wps or wps_ or gwps_ nameing in skin_engine/ ... these will be renamed as this work gets finished

* Move strncpy() from core to the pluginlib
* Introduce strlcpy() and use that instead in most places (use memcpy in a few) in core and some plugins
* Drop strncpy() from the codec api as no codec used it
* Bump codec and plugin api versions

viewport_Set_defaults() will setup the given viewport with the correct "full screen" dimensions (so start at 0,0 if statusbars are disabled or 0,8 if they are enabled.)
All screens should keep the statusbar enabled, but if you really want to ignore the user setting you can disbaled it with viewportmanager_set_statusbar(false).
This commit also includes some menu/list viewport cleanups from kugel in FS#9603

The time/date dispaly has been moved out of the "rockbox info" screen and into this screen also (only displayed if there is at least 3 lines of text on the screen though)
The time/date is talked in this screen by pressing the usual context-menu button (usually long-select)
Targets without a RTC are not changed (i.e sleep timer isnt moved)

* Remove gui_splash()
* Rename gui_syncsplash() to splashf() and remove its voice
capabilities.
* Rename the internal splash() to splash_internal() and introduce an
externally visible splash() that handles simple splashing without
printf functionality e.g. splash(HZ, ID2P(LANG_FOO)); or splash(HZ,
"foo"); if a LANG_* id is passed it will be voiced.
* Adjust all places that called gui_syncsplash() to use the correct
variant from above.
* Export both new functions to plugins and adjust places calling
rb->splash() to use the correct variant so that we now have naming
consistency between the core and plugins.
* Fix one latent bug that would cause my sim to crash with the above
changes and correct P2STR and P2ID macros, thanks to pondlife.
