loadenv: allow more fine grained environment loading ...

This implements two new options for the loadenv command:

-s: removes (scrubs) old directory contents to be able to
    create a fresh environment from for example /dev/defaultenv
-n: no overwrite. Do not overwrite existing files. This allows
    to keep parts of the old environment.

ARM omap spi image: print error to stderr ...

Since the utility outputs the image on stdout we have to print the
error messages to stderr in order to see them.

ARM omap spi image: relax size constrains ...

The omap spi utility requires the image size to be a multiple of four
bytes. This seems unnecessary, we can just pad with a few bytes to
get the required alignment.

scripts: add tool to create image for SPI boot on AM35xx ...

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:

- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian

The mk-am35xx-spi-image tool converts barebox.bin to
this format.

environment generation: Fix dependencies ...

The dependencies for generating the environment do not work properly:

- If files are removed from the defaultenv, a subsequent make will not
  update the default environment.
- If CONFIG_DEFAULT_ENVIRONMENT_PATH changes, the default environment
  also will not be regenerated.

This patch fixes this by introducing a cmd_env which has the content of
$(ENV_FILES) in the command so that the if_changed mechanism recognizes
a change when $(ENV_FILE) changes. This also results in a nice "  ENV "
string in the build process.

Make: Fix if_changed when command contains backslashes ...

The call if_changed mechanism does not work when the command
contains backslashes. This basically is an issue with lzo
and bzip2 compressed kernels. The compressed binaries do not
contain the uncompressed image size, so these use size_append
to append the size. This results in backslashes in the executed
command. With this if_changed always detects a change in the
command and rebuilds the compressed image even if nothing
has changed.

Fix this by escaping backslashes in make-cmd

This was worked out together with Jan Lübbe. The same patch
has recently been accepted to the kernel.
