Adding debug statements to this code path does not make much sense
since when enabled it will massively spam the console.

Bootstrap_read_devfs does not remove the devices it creates during the
course of its execution which might be considered as a resource
leak. Remedy that by adding the code to remove those devices upon
function completion.

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.

Original version of 'read_image_head' would not free the memory
allocated for barebox header in cases of any failure. Fix this by
adding a dedicated resourse de-allocation code path.

This corresponds to kernel commit 72cf90124e87d975d0b
This fix ensures that we never meet an integer overflow while adding
255 while parsing a variable length encoding. It works differently from
commit 206a81c ("lzo: properly check for overruns") because instead of
ensuring that we don't overrun the input, which is tricky to guarantee
due to many assumptions in the code, it simply checks that the cumulated
number of 255 read cannot overflow by bounding this number.
The MAX_255_COUNT is the maximum number of times we can add 255 to a base
count without overflowing an integer. The multiply will overflow when
multiplying 255 by more than MAXINT/255. The sum will overflow earlier
depending on the base count. Since the base count is taken from a u8
and a few bits, it is safe to assume that it will always be lower than
or equal to 2*255, thus we can always prevent any overflow by accepting
two less 255 steps.
This patch also reduces the CPU overhead and actually increases performance
by 1.1% compared to the initial code, while the previous fix costs 3.1%
(measured on x86_64).
The fix needs to be backported to all currently supported stable kernels.

This reverts barebox commit ecb1dc0b1e859bca9
This corresponds to kernel commit af958a38a60c7ca3d8
As analysed by Willem Pinckaers, this fix is still incomplete on
certain rare corner cases, and it is easier to restart from the
original code.

If strdup() fails with out-of-memory, __dev_add_param() should fail
with -ENOMEM.
(Note strdup() is always given with a non-NULL pointer. If the
argument name is given with NULL, the system would already have
crashed in the get_param_by_name() function.)

This adds simple console support to the PBL which makes it
possible to print more complex messages in the PBL than just
strings or hex numbers. For now puts_ll is used to print the
messages, so it depends on CONFIG_DEBUG_LL which makes it
more a debugging option. However, this could be extended later
to get regular output from the PBL if desired.

This is done because we want to have printf support in the PBL, but PBL
