Bump to the latest cake recipe.
This backports tc class support to kernel 4.9 and other than conditional
kernel compilation pre-processor macros represents the cake that has
gone upstream into kernel 4.19. Loud cheer!
Fun may be had by changing cake tin classification for packets on
ingress. e.g.
tc filter add dev ifb4eth0 parent 800b: protocol ip u32 match \
ip dport 6981 0xffff action skbedit priority 800b:1
Where 800b: represents the filter handle for the ifb obtained by 'tc
qdisc' and the 1 from 800b:1 represents the cake tin number. So the
above example puts all incoming packets destined for port 6981 into the
BULK (lowest priority) tin.

More important bug fix:
402f05c Use full-rate mtu_time in all tins. Fixes an issue where some
cake tins experienced excessive latency since 49776da (dynamically
adjust target)
Minor bug fixes:
31277c2 Avoid unsigned comparison against zero. Fix compiler warning,
no known impact.
8cf5278 ack_filter: fix TCP flag check. A very contrived case may have
lead to dropping a SYN packet that should not be dropped.

There has been recent significant activity with the cake qdisc of late
but in the cobalt branch. Some of that effort is related to upstreaming
to kernel & iproute2 mainline but we're not quite there yet. Relevant
feature changes:
ingress mode: Instead of only counting packets that make it past the
shaper, include packets we've decided to drop as well, since they did
arrive with us on the link and took link capacity.
This mode is more suitable for shaping the ingress of a link
(e.g. from ISP) rather than the more normal egress.
ptm mode: Minor optimisation in packet overhead calculation.
dual-src/dsthost/triple-isolate: Optimise only calculating src or dst
host hashes only if required.
ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in
highly assymetric links (downstream v upstream capacity) where the
majority of upstream link capacity is occupied with ACKS for downstream
traffic.
A separate iproute2 patch to teach it about Cake's new features will
follow.

The last two parameters passed between user space tc and kernel space
sched-cake were transposed due to a merge mistake in a parameter header
file.
As such, using a packet overhead figure was likely to set cake to wash
packet DSCP values. Similarly, the DSCP wash flag was used as an offset
to the displayed packet overhead value.

Follow upstream cake:
diffserv3: a simple 3 tin classifier more in line with sqm-scripts
defaults for other qdisc algorithms.
defaults: default qdisc options are now diffserv3 and triple-isolate.

Track upstream changes, incl changes in packet overhead accounting
(automatically taking care of linux' packet sizing knowledge),
improvements to triple isolated DRR handling (new flow dominance),
statistics tweak & allow more packet drops in stressed conditions.
Under tests this has significantly improved latency control under
'many flows to one' scenarious as is typical of bittorrent and MS
Windows update.
I also restored 'DSCP washing' functionality in my repo which follows
upstream closely (like a hawk!) with tc keywords 'wash/nowash'. This
allows cake to limit/control packets in bands determined by a packet's
DSCP but to clear those DSCP bits on qdisc egress. This functionality
was originally removed as part of an attempt to push cake into the
kernel, which hasn't actually happened as yet.
A matching commit is required to iproute2/tc to support the new overhead
handling, keyword changes as well as the 'wash/nowash' tweak.

* Change git packages to xz
* Update mirror checksums in packages where they are used
* Change a few source tarballs to xz if available upstream
* Remove unused lines in packages we're touching, requested by jow- and blogic
* We're relying more on xz-utils so add official mirror as primary source, master site as secondary.
* Add SHA256 checksums to multiple git tarball packages

COBALT is a hybrid codel/blue algo combining best elements of both.
Exhibits improved behaviour in presence of abuse from unresponsive flows
handled by 'blue', whereas responsive flows are still handled by codel.
