Per-network option com.docker.network.bridge.trusted-host-interfaces
accepts a list of interfaces that are allowed to route
directly to a container's published ports in a bridge
network with nat enabled.
This daemon level option disables direct access filtering,
enabling direct access to published ports on container
addresses in all bridge networks, via all host interfaces.
It overlaps with short-term env-var workaround:
DOCKER_INSECURE_NO_IPTABLES_RAW=1
- it does not allow packets sent from outside the host to reach
ports published only to 127.0.0.1
- it will outlive iptables (the workaround was initially intended
for hosts that do not have kernel support for the "raw" iptables
table).

commit 1932091e21 removed support
for the --allow-nondistributable-artifacts, but forgot to remove
this section.

Non-distributable artifacts (foreign layers) were introduced in commit
05bd04350b to accommodate Windows images,
for which the EULA did not allow layers to be distributed through registries
other than those hosted by Microsoft. The concept of foreign / non-distributable
layers was adopted by the OCI distribution spec in [oci#233].
These restrictions were relaxed later to allow distributing these images
through non-public registries, for which a configuration was added in the
daemon in 67fdf574d5. In 2022, Microsoft updated
the EULA and [removed these restrictions altogether][1], and the OCI distribution
spec deprecated the functionality in [oci#965].
In 2023, Microsoft [removed the use of foreign data layers][2] for their images,
making this functionality obsolete.
This patch:
- Deprecates the `--allow-nondistributable-artifacts` daemon flag and corresponding
`allow-nondistributable-artifacts` field in `daemon.json`. Setting either
option will no longer take an effect, but a deprecation warning log is added
to raise awareness about the deprecation. This warning is planned to become
an error in the next release.
- Deprecates the `RegistryConfig.AllowNondistributableArtifactsCIDRs` and
`RegistryConfig.AllowNondistributableArtifactsHostnames` fields in the
`GET /info` API response. For API version v1.48 and lower, the fields are
still included in the response, but always `null`. In API version v1.49 and
higher, the field will be omitted entirely.
- Deprecates the `api/types/registry/ServiceConfig.AllowNondistributableArtifactsCIDRs`
field.
- Deprecates the `api/types/registry/ServiceConfig.AllowNondistributableArtifactsHostnames`
field.
- Deprecates the `registry.ServiceOptions.AllowNondistributableArtifacts` field.

Use the same logic to generate IPAMConf for IPv6 as for IPv4.
- When no fixed-cidr-v6 is specified, rather than error out, use
the default address pools (as for an IPv4 default bridge with no
fixed-cidr, and as for user-defined networks).
- Add daemon option --bip6, similar to --bip.
- Necessary because it's the only way to override an old address
on docker0 (daemon-managed default bridge), as illustrated by
test cases.
- For a user-managed default bridge (--bridge), use IPv6 addresses
on the user's bridge to determine the pool, sub-pool and gateway.
Following the same rules as IPv4.
- Don't set up IPv6 IPAMConf if IPv6 is not enabled.

The daemon no longer depends on the iptables/ip6tables filter-FORWARD
chain's policy being DROP in order to implement its port filtering
rules.
However, if the daemon enables IP forwarding in the host's system
config, by default it will set the policy to DROP to avoid potential
security issues for other applications/networks.
If docker does need to enable IP forwarding, but other applications
on the host require filter-FORWARD's policies to be ACCEPT, this
option can be used to tell the daemon to leave the policy unchanged.
(Equivalent to enabling IP forwarding before starting the daemon,
but without needing to do that.)

Support the use of `make install` in packaging scripts, where the
$mandir tree might not exist under $DESTDIR.
For portability, create the parent directories using a separate install
command instead of relying on the non-portable `-D` flag.
Set errexit so the install target fails if any install step fails.

Mostly, this makes sure that literals (such as true, false, host,
private, examples of options usage etc.) are typeset in bold, except for
filenames, which are typeset in italic.
While at it,
- remove some default values from synopsis as it should not
be there;
- fix man pages references (page name in bold, volume number in
regular).
This is not a complete fix, but a step in the right direction.

1. Escape asterisks and underscores, that have special meaning in
Markdown. While most markdown processors are smart enough to
distinguish whether it's a literal * or _ or a formatting directive,
escaping makes things more explicit.
2. Fix using wrong level of headings in some dm options (most are ####,
but some were #####).
3. Do not use sub-heading for examples in some dm options (this is how
it's done in the rest of the man page).
