Merge ~xnox/ubuntu/+source/linux-snap/+git/bionic:master into ~ubuntu-kernel/ubuntu/+source/linux-snap/+git/bionic:master

[Dimitri John Ledkov]

lzma is deprecated, lz4 is the new world order.

This fixes FTBFS of the snap kernels in devel/eoan.

I've checked the configs and lz4 decompress should be enabled on all snap kernels already via the sample-kernels, as dep of squashfs_lz4 or some such. Thus compressing with lz4 should be safe in that regard (it should still boot). Also lz4 is the default across all of ubuntu since 18.10.

Pin any PPAs to the same priority as -updates.

PPAs only have "release" pocket, and do not have -updates, thus at the
moment they get pinned down lower than -updates. Normally, the
snappy-dev/image ppa should be treated on the same priority as
-updates.
