Before this was just implemented inline wherever it was needed. Now
it is provided as 2 inline functions in a header called checksum.h.
There should be no differences in actual behavior.

This removes all the pre-release bootloader of version 7 and
replaces them with production releases of version 8. The
pre-releases have their own problems and should be left
behind as they were never officially released.

The table is now gated by the FLASH_SIZE macro as any given
target will not have a known rom chip of a differing size
than the FLASH_SIZE. This will reduce the resulting code
a bit as well.

I discovered it was doing this on the H300 during longer operations
and I freaked out at first. This disables this feature until the
program is finished so as to not give anyone else an unnecessary
fright while using it. It will also cut down on frivilous reports.

This overhauls most of the code to be easier to understand in terms
of the interactions with the flash. I found the original to be rather
confusing with how it kept switching between byte and word offsets.
My solution was to make all external access to the flash in terms of
sectors and bytes. Whatever the flash uses internally is now handled
by the subroutines for performing the erase, program, and verify
operations.
This helps make it far more consistent for the code that actually uses
these operations as they do not need to concern themselves with word
sizes and offsets anymore.
As a side effect of this change the flash operations are now done
entirely by subroutines; even the batch operations that used to use
custom loops.
Additionally some functions were merged with other functions in order
to reduce the amount of functions as well as consolidating common
code fragments.

Nothing in the core has used it for some time. It's exported to the
plugin API but the last plugins to use it were switched to the mixer API
back in 2011.
This allows us to get rid of pcm_play_dma_pause() from all audio drivers

First the argument should be const since the original parameter is.
Second the pointer arithmetic for detecting whether rockbox is running
from ROM or not is incorrect. It ends up being at a location twice as
far as intended since the arithmetic does not account for the pointer
type's underlying size. It should also be dependent on the target's
FLASH_SIZE.
Third the LCD setup is moved to the entry point since it is the best
place to setup and restore the LCD changes.

The main change is revising how the checksums are guarded by macros.
But both are also converted to static linkage so they can be better
optimized by GCC. I also change the types around to reflect how the
space the data types actually need. Furthermore I make use of C99
changes to how variables can be declared to move them closer to where
they are used.

This moves the checksum into the local stack and turns the second
parameter into an optional argument. This also reads the model
segment that was previously unused so it can also be checked as
an extra safeguard in the event the checksum somehow matches
yet the model is incorrect.

First neither of these functions can fail on supported targets
so they have become void functions. Their return values were
not being used anyway.
Second support for other flash chips not even used on the
supported targets has been removed. It appears they were
only ever used on the discontinued Arch devices.
Third cfi_read_id was restructured to remove obsolete code
for error checking that is not necessary at all. The datasheets
appear to indicate that the commands used cannot fail.
Fourth cfi_get_flash_info was restructured to use a new approach
to initializing the flash_info struct. It no longer initializes
the structure twice.
Fifth the relevant code has been updated to use the full 16 bits
that are exposed by the flash rom ID interface.

This uses the toggle bit method referenced in the datasheets for the
supported ROM chips and moves the code to a reusable subroutine. It
also introduces a short delay to give the bus a chance to recover. The
older ROM datasheet doesn't mention this delay as necessary but the
newer one does so it now does this for both.

I'm currently running up against the limitations of the lcd_draw functions
I want these functions to be able to be used on any size buffer not
just buffers with a stride matching the underlying device
[DONE] allow the framebuffer to be decoupled from the device framebuffer
[DONE need examples] allow for some simple blit like transformations
[DONE] remove the device framebuffer from the plugin api
[DONE}ditto remote framebuffer
[DONE] remove _viewport_get_framebuffer you can call struct *vp = lcd_set_viewport(NULL) and vp->buffer->fb_ptr
while remote lcds may compile (and work in the sim) its not been tested on targets
[FIXED] backdrops need work to be screen agnostic
[FIXED] screen statusbar is not being combined into the main viewport correctly yet
[FIXED] screen elements are displayed incorrectly after switch to void*
[FIXED] core didn't restore proper viewport on splash etc.
[NEEDS TESTING] remote lcd garbled data
[FIXED] osd lib garbled screen on bmp_part
[FIXED] grey_set_vp needs to return old viewport like lcd_set_viewport
[FIXED] Viewport update now handles viewports with differing buffers/strides by copying to the main buffer
[FIXED] splash on top of WPS leaves old framebuffer data (doesn't redraw)
[UPDATE] refined this a bit more to have clear_viewport set the clean bit and have skin_render do its own screen clear
scrolling viewports no longer trigger wps refresh
also fixed a bug where guisyncyesno was displaying and then disappearing
[ADDED!] New LCD macros that allow you to create properly size frame buffers in you desired size without wasting bytes
(LCD_ and LCD_REMOTE_)
LCD_STRIDE(w, h) same as STRIDE_MAIN
LCD_FBSTRIDE(w, h) returns target specific stride for a buffer W x H
LCD_NBELEMS(w, h) returns the number of fb_data sized elemenst needed for a buffer W x H
LCD_NATIVE_STRIDE(s) conversion between rockbox native vertical and lcd native stride (2bitH)
test_viewports.c has an example of usage
[FIXED!!] 2bit targets don't respect non-native strides
[FIXED] Few define snags

It was originally hard-coded at 0x200 which is 512 sectors. This
only works for the H100 and H120. The larger ROM of the H300 is 1024
sectors in size. In either case the bootloader starts 16 sectors before
the end of the ROM so rely on this fact to correctly calculate where to
stop the bootloader erasure.

* HOME_DIR is now either "/" or special "<HOME>"
* target-specific "home dir path" is defined solely by PIVOT_ROOT
* PIVOT_ROOT path is now defined in toplevel config files
* Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
* Do not prepend PIVOT_ROOT path if the path already has it!
* Do not play these games for __PCTOOL__ builds

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?
