uncompress_buf is used each time uncompress is called, so
make sure it is initialized correctly so that we do not
call free() on an already free pointer.

uncompress() has the same prototype as the various kernel decompress
functions. It automatically detects the compression type and selects
the correct uncompress function.

Allow the user to manually select the uncompression support
he wants to have so that we have a single point where a user
can see which uncompression support will be compiled in.

The kernel uncompression functions have a unified API. Switch
to the kernel implementation to unify the different uncompression
APIs. As a bonus the kernel implementation is much smaller.

If read_key is feeded by STRG + KEY_LEFT you run into the while(1)
loop and corrupt memory through esc array.
Force return if index gets too high.

unlzo support is broken for files > 256k (more than one block)
since commit a3463cc128
(lib/decompress_unlzo: use fill and full to read and write data)
This patch updates unlzo support to the latest version of the kernel
plus a small buffer free fix.

This adds basic device tree command support. So far we can
parse a flat device tree (-p), which also stores the tree
in memory, dump it (-d) and free (-f) the internally stored tree.
The chosen node can be updated with barebox bootargs, no other
device tree manipulation is implemented yet.

We might want to add real resource tracking later. Also
The first resource may not be a IORESOURCE_MEM at all.
For these reasons introduce a wrapper function for
driver so that they do not have to fiddle with resources
directly.

for now we keep the old map_base and size temporary but will switch all of
the used step by step to them resource way
and mirror the first resource to the map_base and size if available

With this kallsyms finally start working at least on ARM. This
enables us resolving addresses into symbols which is particularly
useful in combination with stack unwinding support. As kallsyms
now compile and work we can remove the depends on BROKEN.

this will all to simplify the sync with the kernel and later easly add the
self decompression support to barebox
as example with a lzo compression will reduce barebox from 180224 to 99863
bytes so 55.41%

we also reduce the binary size by 224 bytes

The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().
