The X cursor postion can be calculated based on the backporch and
interleave values. In the emulation we ignore the HP-UX settings for
backporch and use instead twice the size of the emulated cursor. With
those changes the X-position of the graphics cursor is now finally
working correctly on HP-UX 10 and HP-UX 11.

Drop the hard-coded value of 1146 lines which seems to work with HP-UX
11, but not with HP-UX 10. Instead encode the screen height in byte 0 of
active_lines_low and byte 3 of misc_video as it's expected by the Xorg
X11 graphics driver.
This potentially allows for higher vertical screen resolutions than
1280x1024 with X11.

The framebuffer_update_display() function returns the dirty scanlines that were
touched since the last display update, however artist_update_display() always calls
dpy_gfx_update() with start and end scanlines of 0 and s->height causing the
entire display surface to be rendered on every update.
Update artist_update_display() so that dpy_gfx_update() only renders the dirty
scanlines on the display surface, bypassing the display surface rendering
completely if framebuffer_update_display() indicates no changes occurred.
This noticeably improves boot performance when the framebuffer is enabled on my
rather modest laptop here, including making the GTK UI usable.

Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.
This can help to make some code independent from qemu too.
gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

This patch fix the behaviour and positioning of the X11 mouse cursor in HP-UX.
The current code missed to subtract the offset of the CURSOR_CTRL register from
the current mouse cursor position. The HP-UX graphics driver stores in this
register the offset of the mouse graphics compared to the current cursor
position. Without this adjustment the mouse behaves strange at the screen
borders.
Additionally, depending on the HP-UX version, the mouse cursor position
in the cursor_pos register reports different values. To accommodate this
track the current min and max reported values and auto-adjust at runtime.
With this fix the mouse now behaves as expected on HP-UX 10 and 11.

When writing this code it was assumed that register 0x118000 is the
buffer access mode for color map accesses. It turned out that this
is wrong. Instead register 0x118000 sets both src and dst buffer
access mode at the same time.
This required a larger rewrite of the code. The good thing is that
both the linear framebuffer and the register based vram access can
now be combined into one function.
This makes the linux 'stifb' framebuffer work, and both HP-UX 10.20
and HP-UX 11.11 are still working.

As further simplification the extraction of the x/y coordinates for

vram_bit_write(), so move this code up into the function.
