Nexus 5: b16-L / b2-M

Since M-preview sources on shamu were also working on Lollipop and improved idle drain and snappiness, I've also tried to merge the M-preview stuff into our Lollipop kernel. The kernel runs more than 24 hours on several devices and seems to run quite well. I've updated BFQ I/O sched and merged some little fixes for other subsystems on both releases (-L and -M). I still do two builds, since the -M kernel needs Selinux to be disabled to allow root, and the Lollipop kernel doesn't need that.

Changelog:
Lollipop:
-merged M-preview source
-updated BFQ
-merged little fixes here and there
M-preview:
-updated BFQ
-merged little fixes here and there
