* qubesos/pr/25:
replace tinting algorithm with one that partially preserves saturation too
reimplement tint algorithm with numpy for reasonable performance
use PIL image library instead of ImageMagick to load/save images when tinting
add Python pillow and numpy dependencies
remove unused cairo import
Try to find root filesystem by partition label (not filesystem label!).
If that fails, default to 3rd partition according to (new) default
layout.

This will allow to boot the HVM using provided kernel directly (loaded
by qemu in stubdomain), without need for additional bootloader.

Getting loop device backing file path was broken:
${NAME%p*} for not-partitioned devices will cut the actual device name.
Use full name instead. This probably breaks handling partitioned
devices, but such devices should not appear in a directory flagged to be
ignored (VM images)

GCC crash because of -Werror=implicit-fallthrough. However the fallthrough exists but has a typo.
Thanks for omac777 analysis (7d0b8155a3)

(cherry picked from commit ea0c714139)
1. Do not detach device forcefully when it's removed. This breaks
libvirt (which thinks the device is still there). After this change, it
is possible to detach device using libvirt, even if it was already
removed physically from backend domain (unless it is dom0 - in which
case it is still broken). So, this is partial fix for
QubesOS/qubes-issues#1082.
2. Do not trigger "change" udev event when only QubesDB state needs to
be updated - this leads to massive udev events queue, and heavy I/O
usage - for example scanning all LVM many times. In some cases it even
caused infinite event queue.
3. Do not use QUBES_EXPOSED udev property - it was needed a while back
before QubesDB, because concurrent xenstore accesses are expensive
(because of transactions). It isn't the problem on QubesDB.
4. Cache information about device-mapper, so it is possible to
reconstruct it at device remove - when the actual device cannot be
queried anymore. This is specifically about list of lower layer devices
used.
5. Allow excluding loop devices pointing at a file in directory marked
with ".qubes-exclude-block-devices" file. This is more generic than
hardcoding /var/lib/qubes.

int(ceil(log10(100))) is one lower than it should be when max widths are
powers of 10. This means providing a value of 100 when the max is 100
produces an unexpected failure.
Was never triggered because imghdrlen args are only hard-coded
constants, but a bug is a bug.
Before this commit u2mfn got the address via kmap(get_user_pages(...)).
This has the problem that get_user_pages() does not work in some cases.
For example when qemu in a stubdom tries to get the mfn for a page which
is mapped from the target domain u2mfn fails because get_user_pages()
cannot be used for such mappings.
So get the address from the pte with apply_to_page_range(). Since we are
only interested in one page get_locked_pte() would be simpler but it's
not available to modules.
