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.

If logf is enabled, panic() will print the last lines. On small
screens this is more or less useless, but on large screens it
can be very useful for debugging.

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.

Greylib performed a horrible hack and stored fg and bg patterns in other
struct viewport fields. One of them was just removed. So instead of
this hack simply enable the *_pattern fields for mono targets as well,
so that greylib can use them normally.

These where used for line styling during scrolling, which is now done in apps/,
The viewport struct doesn't need to record these anymore.

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).

This main (and only) purpose for it was to adjust the pixel position of the text
in otherwise linebased (scrolling) functions. With pixel-based scrolling
this isnt necessary anymore.

Since scrolling is now pixel-based this is not necessary anymore. custom line
height is handled by put_line() but can also possible to implement with
lcd_puts_scroll_func().

With this functions removed there is no exported function in firmware left
that draws line decorations. Also no function supports specifying an y-offset
anymore (was used for pixel accurate positioning of otherwise strictly line-based
API calls).
Both should be handled in apps/ now.

It is similar to lcd_gradient_fillrect(), except that it only draws a part
of the complete gradient. This can be used to draw only the bottom half
of a full gradient.

This function supports installing a custom scroll callback. This will be
called when the scrollengine redraws the line. It allows to draw extended
styles (or anything your can possible imagine) along with the text.
It is also strictly pixel-based, the first pixel-based function that supports
scrolling.

disconnect() needs to be called exactly once per call to init_connection().
In case of bus resets, disconnect() was not called, which led to leaking
alloc_maximum() allocated buflib handles, which led to buflib running out
of memory to allocate.

Some seldomly used drawmode combinations did not work in conjunction with
alpha bitmaps and backdrops. Now all should work (see comment added) by using
more bits.

bpb_is_sane() used to effectively multiplying the sector size (relative
to 512 bytes) twice, which meant that filesystems with e.g. 2K sectors and
32 sectors per cluster were rejected because while this adds up to 64K
clusters (i.e. the upper limit), the calculation wrongly came to 256K.
This bug tends to affect 5.5G ipods when formatted using dosfstools.

This fixes the radioart crash that was the result of buffering.c working
on a freed buffer at the same time as buflib (radioart uses buffering.c for the
images). With this change the buffer is owned by buflib exclusively so this
cannot happen.
As a result, audio_get_buffer() doesn't exist anymore. Callers should call
core_alloc_maximum() directly. This buffer needs to be protected as usual
against movement if necessary (previously it was not protected at all which
cased the radioart crash), To get most of it they can adjust the willingness of
the talk engine to give its buffer away (at the expense of disabling voice
interface) with the new talk_buffer_set_policy() function.

This function relocates a buflib back buffer, updating pointers in struct
buflib_context. It does not move any data by itself.
The intended use-case is buflib-on-buflib, where a buflib back buffer is
allocated with buflib and attempted to be moved. The move_callback() can call
this and return BUFLIB_CB_OK on success. No move_callback() is called for the
subordinate buflib buffer, therefore it must not contain non-movable
allocations. The caller is generally responsible moving the data and all its
implications.

This function will now ask shrinkable allocations to give up all of their
memory. With future support of playback.c this can be used as a safe
replacement for audio_get_buffer().

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.
