All three functions are nearly identical regardless of the
LCD pixel format. Consolidate them into a generic version in
lcd-bitmap-common.c.

In-viewport clipping code is duplicated across 8 files, making
it a chore to change anything related to clipping; refactor the
clipping logic into dedicated functions.

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.

This was only enabled for the mrobe500 and sansaconnect targets.
Most targets are therefore running without this "safety" measure,
and presumably we'd have noticed long ago if there was a problem.
So in all likelihood this is just a bunch of dead code that we
don't need to carry around.

flags were getting un-initialized memory
it really didn't matter with the flags getting initialized
anyway
But once I added a new flag that didn't explicitly
set or clear the flag at init well here we are
set flags to VP_DEFAULT_FLAGS in viewport_set_defaults()
add the flags variable to the default vp's set to 0
(it was already initialized to 0 by bss, make it explicit)

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

-- apparenty 0x4 aligned doesn't work properly
requires 0x8 alignment at least for the h10 20gb
but enabled for all arm processors
assign the default framebuffer to the default_vp as well

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

On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h

With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.
It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.
lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.
All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

An upcoming lcd-24bit.c driver will re-use a lot of code from the 16bit
drivers, so prepare for that.
