edit: return error when save_file failed ...

When writing a file failed (e.g. due to a read-only file system), no
error was reported by the 'edit' tool. To be valid (and to not confuse
the poor user) at least '1' should be returned to indicate an error.

edit: handle write() call errors in save_file() ...

save_file() did ignore possible errors of its write() calls.
Now the error code is used as return code for save_file().

write_full() is used instead of write() as it does not perform partial
writes which would require to check for returned size, too.

mci: Print versions with micro levels correctly ...

The version is stored as BCD, e.g. 0x40 -> ".4" and 0x41 -> ".41".
The latter was getting printed as ".65".  Simplify the logic a bit to
not split the minor into nybbles just to re-assemble it into a byte
again.

Make list of flash images and fix link all single image cases ...

Create a new file named 'barebox-flash-images' in the top level output
directory that lists each image generated, one per line.  Paths will
be relative to the top level output directory.  This works if multiple
images are generated as well as for a single image.

Also update the existing barebox-flash-image symlink to point to the
image in all cases where there is a single image generated.  If
multiple images are generated, it will point to the non-existent file
'multi-image-build'.

of_dump: Add option to print node names only ...

Devicetrees tend to become very long and it is hard to find the
interesting nodes in a full tree output.
This patch adds the -n option to the of_node command. With this
option only the names of the nodes are printed, but not the properties.
The resulting output is much shorter and the node one is interested
in can be copy/pasted to a second call to of_node.

common/parser.c: Do not treat zero return code as error ...

common/parser.c: Do not conflate error reporting disciplines ...

Run_command() uses 0 to indicate success and negative values to
indicate errors, whereas execute_command() uses 0 for success and
positive integers to represent error codes. Conflating the two breaks
the code that calls run_command and then checks for error code sign to
detect problems, so avoid that by doing a very simple transformation
on the result of execute_command

arm: Disable unaligned accesses ...

From reading ARM architecture related documentation if appears that
while unaligned memory access is supported by the processor in general
it is not supported if MMU is disabled.

The problem in question can be easily reproduced by building the code
without this patch, MMU disabled, and trying to run 'memtest'
command. Which would in turn call mem_test() which would eventually
call show_progress(). That last function, if build without
-mno-unaligned-access would result in unaligned memory access which
would result in Barebox hanging.

This patch instructs the compiler to not generate any unaligned
accesses to memory thus avoiding the problem.
