To support fm radio a kernel module was written. This module is added to
the patched firmware that loads Rockbox. It's pre-compiled but its source
archive provided.
The kernel module provides raw-access to the built-in si4709 radio chip.
Our existing si 47xx drivers can be re-used this way.
The module itself was written Lorenzo Miori, I only integrated it
into the tree.

Emulates the basic "Meier" crossfeed (2 capacitors, 3 resistors)
as discussed in
http://www.meier-audio.homepage.t-online.de/passivefilter.htm
This crossfeed blends a bit of low-pass filtered L signal into
the R signal (and vice versa) while adding about 300 us delay
to the crossfed-signal. A difference with the crossfeed already
present in rockbox, is that this algorithm keeps the total
spectrum flat (the one currently in rockbox accentuates
low-frequency signals, making it sound a bit muffled).
This implementation is quite lightweight, just 3 multiplies per
left-right pair of samples. Has a default C implementation and
optimized assembly versions for ARM and Coldfire.
The crossfeed effect is quite subtle and is noticeable mostly
one albums that have very strong left-right separation (e.g.
one instrument only on the left, another only on the right).
In the user interface, the new crossfeed option appears as
"Meier" and is not configureable. The existing crossfeed is
renamed to "Custom" as it allows itself to be customised.
There is no entry for the user manual yet.

Doesnt fix an actual bug because closing a handle is a no-op on all
native targets and others dont use overlay.

Refactor native/hosted implementation seperation while at it

The logic got broken by 6b8330d2.
Since the ifp700 port is basically unmaintained and unfinished and doesn't
build anyway, we can remove the special-casing for it. This simplifies the
logic to "hosted or native, except for bootloaders", which simplifies
further to "not bootloaders".
Fixes FS#12685

When allocating the voice buffer, it's supposed to start at the beginning
of the audio buffer, not at the end of the voice buffer. ;-D
Might clear up a thing or two.

Instead of using the date the voice file was created use the version of Rockbox
the voice file was created for. That way it is possible to see from the
installation log if the installed voice matches the current Rockbox version.

Instead of using some arbitrary and not really useful string use the timestamp
of the downloaded file if version string is provided by the caller. This also
makes it possible to check if the downloaded file is actually a different one.
Use it for manual and game file downloads, as this gives more reasonable values
than using the date transmitted for daily (archived) build and as support for
archived builds will be removed shortly.

Apparently I got the "just-in-case" RXFIFO purge in there before the
RXFIFO was enabled, causing severe hardware spasms.

When it was inactive but enabled, the format change hook was dropping
through to code that it shouldn't execute without it also being active

...by default where they would be interpreted as valid but not actually
be which would cause calls to buffering while it was not initialized.
Add BUFFER_EVENT_BUFFER_RESET to inform users of buffering that the
buffer is being reinitialized. Basically, this wraps all the
functionality being provided by three events (...START_PLAYBACK,
RECORDING_EVENT_START, RECORDING_EVENT_STOP) into one for radioart.c,
the only user of those events (perhaps remove them?) and closes some
loopholes.

Commit bb24ac8c27 replaced the
\opt{iaudiom3,iriverh100} with \opt{remote} which isn't true in the
Iaudio M3 case as this feature is dependent on HAVE_REMOTE_LCD and
the M3 uses this screen as main lcd so doesn't define it. Use the manual
HAVEREMOTEKEYMAP for now as I didn't find a suitable other define yet.

Create symlinks to the iaudiom3 graphics to not duplicate the picture itself
and to not lose the precise 'addressing' of the picture. Change the manual's
makefile to follow symlinks for this to work (thanks to Dominik and Jens for

Several of the problem samples on the tracker use values outside this
range. Trying the larger table doesn't quite seem to fix things, but
its only a small amount of additional memory and looking at ffmpeg,
I think the larger table is correct.

Because DMA descriptors needs to be committed and discarded from
the cache, if they are not cache aligned and/or if their size
is not a multiple of cache ligne, nasty side effects could occur
with adjacents data. The same applies to DMA buffers which are
still potentially broken. Add a macro to ensure that these
constraints will not break by error in the future.
