Only the primary contexts (standard, wps, quckscreen, tree, radio)
handle the new keys so far.
Todo contexts: Settings, keyboard, pitchscreen, bookmark, & recording.
Available docs for MODE4 don't list anything other than playback
controls, so it's not clear if there is a path forward here.

GCC 4.9 always emits assembly with divided syntax. Setting unified
syntax in inline assembly causes the assembler to complain about
GCC's generated code, because the directive extends past the scope
of the inline asm. Fix this by setting divided mode at the end of
the inline assembly block.
The assembler directives are hidden behind macros because later
versions of GCC won't need this workaround: they can be told to
use the unified syntax with -masm-syntax-unified.

It's usually only called from init() in main.c, so this is safe.
There is one more call in system-dm320.c from system_init(), but
that's also "safe". I don't know if it's okay to call i2c_init()
twice, but presumably it works...

On single-core targets, system_init() is only called from init()
in main.c, which is also INIT_ATTR, so this is safe.
Multi-core targets additionally call system_init() from cop_main(),
which isn't marked INIT_ATTR. I'm fairly certain that it would be
safe to add INIT_ATTR to cop_main() with a bit of refactoring, but
I don't have a way of testing it. So for now, leave INIT_ATTR off
for multi-core targets.

Instead of putting "#ifdef LCD_STRIDEFORMAT" at every usage of the
macro it's simpler to have config.h define LCD_STRIDEFORMAT to the
default of horizontal stride when the target leaves it unspecified.

Calling multiple levels of indirection in a loop slows things down
Really these need to be rewritten to take a start and end address
like most of the rest of the codebase
But this is safer without having test hardware in hand

The implementation of write_bootdata() and get_redirect_dir() was
copied verbatim in two different places, obviously a bad thing for
maintainability. This moves them to a new file multiboot.c as they
are only used for multiboot.

This kind of reverts 7b596416bf ("Gigabeat S: Update RDS processing to
use asynchronous I2C rather than thread."). However, requiring RDS to
run in thread context will a) allow more upcoming features and b) remove
quite some complexity from the codebase (see the diffstat here) because
Gigabeat is the only user. iMX31 should be able to handle one more
thread, as it can even run Linux.

Based on a patch by Amaury Pouly which was based on a patch from Ryan
Hitchman.
I mainly moved the code for polling into the tuner driver so it can be
reused by other targets. I added the CONFIG parameter for the polling
frequency (in ticks) to save energy. Also, I did some minor cleanups.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

It has only a couple GB of onboard flash storage with no storage
driver in Rockbox. It hasn't seen any meaningful development since
its initial commit, it's not on the build farm, and the bootloader
build is broken by other refactoring.

Do not introduce any change for M:Robe 500 as it uses the two LCD frames
in non-obvious way.
Sansa Connect and Creative ZVM use only single front framebuffer.
Place TTB at DRAM end to minimize memory loss due to alignment.
Reserve as little as possible memory for the LCD frames.
On Sansa Connect this change extends audio buffer by 858 KiB.

AVR interrupt signal can remain active if the state has changed during
state read. In such case, there won't be intterupt and the interface
would appear unresponsive until AVR thread received event (e.g. USB
connection/disconnect). Solve the issue by not waiting for event if AVR
interrupt signal is active prior to event wait.

Make it possible for target to provide voltage, percentage and time to
empty values. The voltage measurement is nice to have in debug menu even
if the actions are taken only based on percentage. Perform battery level
estimation based on voltage only if percentage is not available.
Use time to empty based on actual power consumption. This makes the
estimated runtime displayed in Rockbox Info to react to backlight
setting. The bq27000 updates time to empty estimate every 5.12 seconds
so it is possible to see the estimate with backlight off on the screen
if user enters Rockbox Info, activates hold switch, waits 11 seconds and
releases the hold switch.

AVR requires bigger delays between retries. Read state instead of
version for synchronization purposes as it shifts more bytes.

If the commands repeatedly fail it is likely that the AVR is not
programmed. In such case simply continue normal operation. This is
especially important in bootloader as it makes it possible to load new
rockbox build using bootloader USB mode. Otherwise, the only recovery
option would be to use I2C serial.

Use 32-bit monotime AVR counter for time tracking. Set the time by
adding fixed offset to the counter value. Store the offset in rockbox
directory to make it persistent between reboots.

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).

Wait on semaphore until DMA finishes instead of busy waiting. This
allows the CPU to be used by other tasks during transfers.
Increase peripheral clock frequency, divide AHB by 2 instead of 3.
Function clock frequency is AHB divided by MMC divider + 1.

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.
