The old max dma transfer size was set to 2^15 because allowing
values up to 2^16 would result in overflow of the transfer count
in many places. This was a problem with the old register headers
because the macros didn't make sure the result is contained in
the bitmask of the field. The new macro do so 2^16 will actually
end up being 0 which means 2^16 for the hardware. This is kind of
hacky but it works and I prefer that this stays a power of two
because setting it to 2^16-1 would be extremely weird.

- take advantage of the new rmi power function implemented to:
1) lower usual power_mode to low_power as it seems to be enough and might save
some battery
2) implement a system that lower that state to very_low_power
after 1 minute of inactivity.
3) implement touchdev_enable(bool) that can be use later to disable the
touchpad when needed
4) improve the debug screen report of the current power state and
changing the power state using volume keys

The code was broken in a subtle but crucial way: storage idle
callbacks are oneshot so after the first flush everything would
stay in the buffer forever and would never be written to the disk
thus resulting into many events being lost. This changed correctly
registers the idle callback each time the buffer is not empty.
Note that the idle storage code checks if a callback
has is in the queue already so we don't register twice.

The old code used get_action which is bad because it belongs to
apps/. Instead rewrite a simple version of get_action, also
rewrite the top level handler. Since the number of screens is
becoming quite high, it now shows a list and the user can start
from any screen. Once in a screen and as long as the user presses
select, it will advance to next screen until it finally returns
to the list on cancellation.

The current code was spreaded over power and powermgmt which made
it behave strangely, especially since there are relationships
between power management and frequency scaling. The new code makes
sure power management is initialised before frequency scaling
starts. It also makes sure to start from a known state, thus
fixing potential issue when the bootloader stops in a trickle
state where DCDC is improperly configured.

buflib_allocatable() is what buflib_available() was before (it was in fact
simply renamed). It returns the largest contiguous block of memory. This
can be allocated and will definitely succeed, although larger allocations
may also succeed if the buffer can be compacted and shrinked.
buflib_available() now counts all free bytes, contiguous or not. This
better matches the description and how the caller use it.

Replaces the NATIVE_FREQUENCY constant with a configurable frequency.
The user may select 48000Hz if the hardware supports it. The default is
still 44100Hz and the minimum is 44100Hz. The setting is located in the
playback settings, under "Frequency".
"Frequency" was duplicated in english.lang for now to avoid having to
fix every .lang file for the moment and throwing everything out of sync
because of the new play_frequency feature in features.txt. The next
cleanup should combine it with the one included for recording and
generalize the ID label.
If the hardware doesn't support 48000Hz, no setting will be available.
On particular hardware where very high rates are practical and desireable,
the upper bound can be extended by patching.
The PCM mixer can be configured to play at the full hardware frequency
range. The DSP core can configure to the hardware minimum up to the
maximum playback setting (some buffers must be reserved according to
the maximum rate).
If only 44100Hz is supported or possible on a given target for playback,
using the DSP and mixer at other samperates is possible if the hardware
offers them.

Basically, just give it a good rewrite.
Software codec recording can be implemented in a more straightforward
and simple manner and made more robust through the better codec
control now available.
Encoded audio buffer uses a packed format instead of fixed-size
chunks and uses smaller data headers leading to more efficient usage.
The greatest benefit is with a VBR format like wavpack which needs
to request a maximum size but only actually ends up committing part
of that request.
No guard buffers are used for either PCM or encoded audio. PCM is
read into the codec's provided buffer and mono conversion done at
that time in the core if required. Any highly-specialized sample
conversion is still done within the codec itself, such as 32-bit
(wavpack) or interleaved mono (mp3).
There is no longer a separate filename array. All metadata goes
onto the main encoded audio buffer, eliminating any predermined
file limit on the buffer as well as not wasting the space for
unused path queue slots.
The core and codec interface is less awkward and a bit more sensible.
Some less useful interface features were removed. Threads are kept
on narrow code paths ie. the audio thread never calls encoding
functions and the codec thread never calls file functions as before.
Codecs no longer call file functions directly. Writes are buffered
in the core and data written to storage in larger chunks to speed up
flushing of data. In fact, codecs are no longer aware of the stream
being a file at all and have no access to the fd.
SPDIF frequency detection no longer requires a restart of recording
or plugging the source before entering the screen. It will poll
for changes and update when stopped or prerecording (which does
discard now-invalid prerecorded data).
I've seen to it that writing a proper header on full disk works
when the format makes it reasonably practical to do so. Other cases
may have incorrect data sizes but sample info will be in tact. File
left that way may play anyway.
mp3_enc.codec acquires the ability to write 'Info' headers with LAME
tags to make it gapless (bonus).
