f6c719d7ec replace strlcpy with strmemccpy
replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation

in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base

8bf8036021 lcd: Fix clear_viewport on grayscale displays
The original drawmode change was "x = (~x & INVERSEVID) | SOLID"
which is essentially XOR'ing the INVERSEVID bit, but I changed it
to mask out INVERSEVID by mistake.

Fixes 44b9785465.

5e7c34f5b3 lcd: Fix off by one error in clipping check
When I converted all the clipping checks in 4b8fe8acd1 I messed
up the hline and vline checks. This produced some weird panics on
the Shanling Q1, probably memory corruption -- but somehow it got
past AddressSanitizer. Go figure.

c607bfac6f lcd: Fix update_viewport() for non-default stride viewports
Simplify update_viewport() by calling update_viewport_rect().
The resulting LCD driver calls are the same either way and
for some reason, update_viewport() didn't handle non-default
stride viewports correctly.

09cb3c7843 lcd: Remove HAVE_VIEWPORT_CLIP
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.

3237ae4a4f LCD core move buf ptr and address look up function viewport struct
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

488a1b983e put_line/scrolling: Make the scroll engine inform custom scrollers about start/stop of scrolling.
With the new lcd_putsxy_scroll_func() code can register custom scroll functions
(put_line() makes use of that). In order for the custom scroller to be able
to properly manage its userdata pointer (set via struct scrollinfo::userdata)
the scroll engine must inform the scroller about start and stop of scrolling.

To inform about start the lcd_scroll_* functions now return true when
the line will scroll. To inform about stop the scroll engine calls into the
scroller one last time, with the text set to NULL.

put_line() can use this to release the userdata registered per scrolling line
so that it can be recycled.

This fixes that some scrolling lines became glitchy after some time because
the userdata was recycled too early.

26b317e094 scroll engine: Factor out renderer function so it can be called by lcd code.
This is used by lcd_puts_scroll_worker() to render the line immediately
instead of waiting for the next scroll tick when only the text was updated.
Previously lcd_puts_scroll_worker() did not render anything in this case
which could lead to visible blinking.

This fixes blinking scrolling lines with dynamic text in the skin engine.

fde92de224 lcd_nine_segment_bmp: Fixes for non-ideal image dimensions.
1) The 9-segment images need not be multiple of 3 pixels anymore. If it
isn't the inner segments will be smaller than the corners.

2) If the desired actual images is not a multiple of the segment sizes the
function drawed more than the desired rectangle. This is fixed by
drawing the last segment only partially.

36e469db8b lcd-common: Remove direct style (line decorations) from lcd-puts* functions.
This logic is moved into apps (put_line()) which can better handle line
decorations with respect to scrolling, mulitline and other complications.

Firmware doesn't need this. The remaining drawing function know only one style,
that is foreground on background/backdrop (changing drawmode is still supported).

50eb528bc1 scroll_engine: Major rework to support pixel-based scrolling and scroll callbacks.
Much of the scrolling work is moved from lcd-bitmap-common to lcd-scroll.c,
a small scroll callback routine remains. This callback can potentially be
overridden by more extensive scrollers.

The callback also gets fed with pixel-based scrolling information, which
finally removes the strict line-based nature of the scroll engine. Along with
this is the change from scroll_stop_viewport_line() to scroll_stop_viewport_rect()
which works on a pixel-based rectangle instead of lines.

The ultimate goal is to move most of the scroll work to apps, which can
much better decide which line decorations to apply etc. This work is laying
the ground work.

framebuffer use %x(backdrop filename) instead of %X() inside
a viewport with %VB.
