Current implementation in hack/make.sh overwrites PKG_CONFIG
if not defined and set it to pkg-config. When a build is invoked
using xx in our Dockerfile, it will set PKG_CONFIG to the right
value in go environments depending on the target architecture: 8015613ccc/base/xx-go (L75-L78)
Also needs to install dpkg-dev to use pkg-config when cross-building

Build currently doesn't set the right name for target ARM
architecture through switches in CGO_CFLAGS and CGO_CXXFLAGS
when doing cross-compilation. This was previously fixed in https://github.com/moby/moby/pull/43474
Also removes the toolchain configuration. Following changes for
cross-compilation in https://github.com/moby/moby/pull/44546,
we forgot to remove the toolchain configuration that is
not used anymore as xx already sets correct cc/cxx envs already.

This reverts commit 2d397beb00.
moby#44706 and moby#44805 were both merged, and both refactored the same
file. The combination broke the build, and was not detected in CI as
only the combination of the two, applied to the same parent commit,
caused the failure.
moby#44706 should be carried forward, based on the current master, in
order to resolve this conflict.

Embedded structs are part of the exported surface of a struct type.
Boxing a struct value into an interface value does not erase that;
any code could gain access to the embedded struct value with a simple
type assertion. The mutex is supposed to be a private implementation
detail, but *network implements sync.Locker because the mutex is
embedded. Change the mutex to an unexported field so *network no
longer spuriously implements the sync.Locker interface.

Basically every exported method which takes a libnetwork.Sandbox
argument asserts that the value's concrete type is *sandbox. Passing any
other implementation of the interface is a runtime error! This interface
is a footgun, and clearly not necessary. Export and use the concrete
type instead.

unshare.Go() is not used as an existing network namespace needs to be
entered, not a new one created. Explicitly lock main() to the initial
thread so as not to depend on the side effects of importing the
internal/unshare package to achieve the same.

- The oldest kernel version currently supported is v3.10. Bridge
parameters can be set through netlink since v3.8 (see
torvalds/linux@25c71c7). As such, we don't need to fallback to sysfs to
set hairpin mode.
- `scanInterfaceStats()` is never called, so no need to keep it alive.
- Document why `default_pvid` is set through sysfs

When userland-proxy is turned off and on again, the iptables nat rule
doing hairpinning isn't properly removed. This fix makes sure this nat
rule is removed whenever the bridge is torn down or hairpinning is
disabled (through setting userland-proxy to true).
Unlike for ip masquerading and ICC, the `programChainRule()` call
setting up the "MASQ LOCAL HOST" rule has to be called unconditionally
because the hairpin parameter isn't restored from the driver store, but
always comes from the driver config.
For the "SKIP DNAT" rule, things are a bit different: this rule is
always deleted by `removeIPChains()` when the bridge driver is
initialized.
Fixes#44721.

If the imported layer archive is uncompressed, it gets compressed with
gzip before writing to the content store.
Archives compressed with gzip and zstd are imported as-is.
Xz and bzip2 are recompressed into gzip.
