Instead of having a fixed array of fonts register the fonts dynamically.
This allows easier adding of fonts to the tree since only one file per
font has to be added and no other files modified.
Currently we have to register the fonts very early before the first
framebuffer is registered. This is because of our limited
dev_add_param_enum() which wants to know the number of elements when
called, so we can't add elements once after we've called
dev_add_param_enum(). Maybe a dev_add_param_array() has to be created
whithout this limitation, but that's left for a future exercise.

Since dev_add_param_enum is passed a pointer containing the actual value
it can contain an invalid value. Protect against it so that we do not
access invalid array elements.

Not only the array containing the pointers should be const but
also the strings themselves, so instead of using const char **
use const char * const *.

So far we only supported blitting the whole screen from the shadow
fb to the framebuffer. Add a function to blit areas.

The fb core now has builtin support for offscreen rendering, use
this and drop offscreen handling in the gui code.

Some character devices may perform meaningful operations in their
implementation of close() -- a good example would be socfpga.c which
checks if the FPGA was programmed succesfully in it's close() method
-- so ignoring return value of this call may cause false positives in
checking exit status for success.

This adds the new barebox logo to the tree. This is added as svg
image which is converted to different png images during build time. The logo
can be found under /logo/barebox-logo-<width>.png in the running barebox.

Allocate the screen dynamically in fb_open. This opens the way to create
a fb_create_screen function which takes a struct fb_info * instead of a
filename. This is suitable for the framebuffer console which already has
a struct fb_info *.

get_pixel converts a 32bit trgb color into framebuffer format. This
is useful for other code aswell, so export it.
Other functions in the graphics utils code use the name get/set_pixel
aswell, but instead of converting data they get a pixel from the framebuffer
or set a pixel on the framebuffer. To separate from these rename the
function to gu_hex_to_pixel.

The MAC dev parameter functions would only be built when CONFIG_NET is
set. This was okay as long as only network devices were using MAC dev
params. This has changed with the merge of the state framework, so
always compile them in if CONFIG_PARAMETER is set.
Fixes:
common/built-in.o: In function `state_mac_create':
common/state.c:387: undefined reference to `dev_add_param_mac'

Bootstrap_read_devfs does not remove the devices it creates during the
course of its execution which might be considered as a resource

In case of a failure in one of the cdev_* functions original version
of bootstrap_read_devfs would not release memory allocated for barebox
header or memory allocated for the image. This commit fixes this by
adding resource deallocation code.
