Due to the LWL/LWR SMP issue on BCM6368, booting with squash might fail
if the rootfs is not word aligned. As a quick fix, work around it by
ensuring this condition is always true.

We do not need to align the start of read only rootfs's to erase blocks.
This allows us to write the squashfs rootfs directly behind the kernel,
potentially freeing up one erase block.
We still need to align for jffs2, so add a flag for imagetag to
optionally align the rootfs start.

Dual image capable CFEs store an image sequence at the same place as
currently OpenWrt stores the actual rootfs length, so it will get
overwritten when flashing through such a CFE.
To prevent this from happening, move the rootfs length field to the next
four bytes, thus completely using the reserved1 field.
Since the reserved1 field is now completely in use, it does not make sense
to allow it to be set from the imagetag utility, so remove the option.

This replaces the proprietary bcmImageBuilder program from the Broadcom source
drops. It basically adds a 256 bytes header in front of the kernel + rootfs
which contains a few text signatures, the locations of the data as well as the
checksums of the data and the tag. It also adds a 12 bytes header in front of
the LZMA kernel which contains the load address, kernel entry and the size of
the compressed LZMA data.
