Commit d47b283df4 ("kernel: Remove fetch target") removed
the 'fetch' target to simplify the Makefile. This left
dependencies on 'sources' lingering. Remove it.

With kernel 5.0.6 we start seeing compile errors such as:
HOSTCXX -fPIC scripts/gcc-plugins/randomize_layout_plugin.o
In file included from <stdin>:1:
/usr/include/libelf/libelf.h:28:5: error: "__LIBELF_INTERNAL__" is not defined, evaluates to 0 [-Werror=undef]
#if __LIBELF_INTERNAL__
^~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
elutils-dev installs a different version of libelf.

All our 4.x kernels had CFQ enabled. This was removed
in 5.x and replaced with BFQ. Enable it.

To reduce the number of kernels we maintain, for s390x
and ar64 we only support the latest LTS and newer kernels.
v4.19.x has been out for a while, so lets remove support for
v4.14.x.

This target allowed to locally download the kernel source
tar balls. We haven't used this foir a while and adding
v5.x kernel support for it would add yet another conditional.
Remove it to keep the Makefile simpler.

The build of the perf utility has been quite bothersome,
with different arches and kernel versions failing.
Since we now have the ful kernel source in the package,
factor out the actual build into Dockerfile.perf

* wg-quick: freebsd: allow loopback to work
FreeBSD adds a route for point-to-point destination addresses. We don't
really want to specify any destination address, but unfortunately we
have to. Before we tried to cheat by giving our own address as the
destination, but this had the unfortunate effect of preventing
loopback from working on our local ip address. We work around this with
yet another kludge: we set the destination address to 127.0.0.1. Since
127.0.0.1 is already assigned to an interface, this has the same effect
of not specifying a destination address, and therefore we accomplish the
intended behavior. Note that the bad behavior is still present in Darwin,
where such workaround does not exist.
* tools: remove unused check phony declaration
* highlighter: when subtracting char, cast to unsigned
* chacha20: name enums
* tools: fight compiler slightly harder
* tools: c_acc doesn't need to be initialized
* queueing: more reasonable allocator function convention
Usual nits.
* systemd: wg-quick should depend on nss-lookup.target
Since wg-quick(8) calls wg(8) which does hostname lookups, we should
probably only run this after we're allowed to look up hostnames.
* compat: backport ALIGN_DOWN
* noise: whiten the nanoseconds portion of the timestamp
This mitigates unrelated sidechannel attacks that think they can turn
WireGuard into a useful time oracle.
* hashtables: decouple hashtable allocations from the main device allocation
The hashtable allocations are quite large, and cause the device allocation in
the net framework to stall sometimes while it tries to find a contiguous
region that can fit the device struct. To fix the allocation stalls, decouple
the hashtable allocations from the device allocation and allocate the
hashtables with kvmalloc's implicit __GFP_NORETRY so that the allocations fall
back to vmalloc with little resistance.
* chacha20poly1305: permit unaligned strides on certain platforms
The map allocations required to fix this are mostly slower than unaligned
paths.
* noise: store clamped key instead of raw key
This causes `wg show` to now show the right thing. Useful for doing
comparisons.
* compat: ipv6_stub is sometimes null
On ancient kernels, ipv6_stub is sometimes null in cases where IPv6 has
been disabled with a command line flag or other failures.
* Makefile: don't duplicate code in install and modules-install
* Makefile: make the depmod path configurable
* queueing: net-next has changed signature of skb_probe_transport_header
A 5.1 change. This could change again, but for now it allows us to keep this
snapshot aligned with our upstream submissions.
* netlink: don't remove allowed ips for new peers
* peer: only synchronize_rcu_bh and traverse trie once when removing all peers
* allowedips: maintain per-peer list of allowedips
This is a rather big and important change that makes it much much faster to do
operations involving thousands of peers. Batch peer/allowedip addition and
clearing is several orders of magnitude faster now.
