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.

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.

This removes the call to button_clear_queue which interfered with the mechanism in action.c to wait for a key
release event when the button context is changed.

For this it needs to look at the plugin header. Since lc_open() doesn't know
it's a plugin, the header needs to be changed slightly to include the new lc_header (which needs to be the first element in plugin_header so it can be casted savely).

Use host's functions for file i/o directly (open(), close() ,etc.), not the sim_* variants.
Some dir functions need to be wrapped still because we need to cache the parents dir's path (host's dirent doesn't let us know).
For the same reason (incompatibility) with host's dirent) detach some members from Rockbox' dirent struct and put it into an extra one,
the values can be retrieved via the new dir_get_info().
Get rid of the sim_ prefix for sleep as well and change the signature to unix sleep().

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

- cosmetics: remove trailing white space
- mark all functions and variables as static
- merge struct definition and declaration when possible
- rename tuner_settings -> settings (because it's shorter)
- remove unused enums
- don't give pointer to settings struct as argument since there is only
one struct, same for the settings filename
- fix error cases in settings load:
reset settings when loading failed
close file when it hasn't the right size
- inline small load/save functions only used once
- remove unused print_char_xy
- inline print_str and print_int_xy, and use lcd_putsf (added to the
plugin API)

It's a used by codec/plugin loading and vastly reduces code duplication. It's also a step forward in getting rid of libuisimulator in the application ports.
Apparently sh needs linker symbols prefixed with _ even if they're referenced without from C code.

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)
