'psplash' uses only one buffer which can cause tearing artifacts. This
change uses the FBIOPAN_DISPLAY ioctl as a way to handle page flipping
and also does that after a vsync interrupt to remove any tearing issues.

Psplash: Fix text width calculation.
Using the "psplash-write MSG <message_text>" command, you can display messages
when the splash screen is running. As part of this, psplash needs to calculate
the height and width of the box to render on the screen to hold the text (which
will appear on top of the background image), which it does in the
psplash_fb_text_size() function in psplash-fb.c.
If the message contains multiple lines (i.e. it contains one or more newline
characters), then it looks like the intention is for psplash to use the length
of the longest single line as the width of this text box. However, there's a
bug in this calculation that leads to some multi-line messages being rendered
off the left edge of the screen, instead of properly centered.
To fix this, each time a newline is encountered, if the width of the current
line (w) is greater than the maximum line width (mw), update the maximum width.
Also, reset the current line width to zero so we can correctly calculate the
width of the next line.

A new fbdev file is needed and should be overrided if needed.
The number contained in fbdev will be used as X in /dev/fbX.
By overriding fbdev you can have a splash screen on another
framebuffer than /dev/fbO.
The getenv(FBDEV) line has been replaced by this option since
the environment variables are not read yet when psplash starts.

This function is not used outside psplash-fb.c and by making it
static inline we keep the performance and also make it portable across
multiple compilers and gcc versions

Up till now, image data with a rowstride larger than the value
expected from width and bytes_per_pixel caused a trapezoid
distortion of the displayed image.
