The system currently throws numerous nasty warning messages during
the boot, about ignored null bytes in input.
This patch adds a filter to the dd command, to filter these null
bytes out, and thus to prevent these warning messages.

copytree() recursively copies the contents of SRC into DEST.
If DEST doesn't exist it is created; if it exists the contents of SRC
get merged into it (duplicate files are overwritten).
img-lib handles identifying and unpacking archives (uncompressed or
compressed) and filesystem images.
Currently tar and gzip are required; cpio and xz are optional, and bzip2
is supported but unused.
