[Merge] lp:~mvo/goget-ubuntu-touch/populate-ab into lp:goget-ubuntu-touch

[Michael Vogt]

I tested this branch this morning and wrote a daily snappy arm image on my card. The image contains both /boot/uboot/{a,b} with kernel/initrd/dtbs as expected.

I then tested this with the snappy-go branch lp:~mvo/ppy/snappy-sync-bootloader-udf that does no longer contains "SyncBootFiles()" and upgraded with a fake stating point of "1" in "system-b". This upgraded the kernel in /boot/uboot/b from the assets/ as expected. Then rebooted, set "system-a" to "1", upgraded and /boot/uboot/a got updated too. I then set system-b to "N-1" (without a kernel update) and updated. This caused no change to the kernels (as expected).

So I think once this branch lands in u-d-f we can simplify the snappy-go code.
