Yu Watanabe 2c7b826ddf network: do not drop foreign config if interface is in initialized state 
If the interface is in initialized state, no network file is assigned to
the interface. If an interface is not managed by networkd, previously,
the foreign configs of the interface was dropped.

Fixes #14250.

Yu Watanabe bf331d8717 network: if /sys is rw, then udev should be around 
This switches detect_container() to path_is_read_only_rw("/sys"), as if
systemd-udevd.service is conditionalized with that way.

This also updates the log message.

Susant Sahani 9942b71089 network: tc introduce sfq - Stochastic Fairness Queueing 
Stochastic Fairness Queueing is a classless queueing discipline.
SFQ does not shape traffic but only schedules the transmission of packets, based on 'flows'.
The goal is to ensure fairness so that each flow is able to send data in turn,
thus preventing any single flow from drowning out the rest.

Lennart Poettering 353b2baa20 tree-wide: clean up --help texts a bit 
This cleans up and unifies the outut of --help texts a bit:

1. Highlight the human friendly description string, not the command
   line via ANSI sequences. Previously both this description string and
   the brief command line summary was marked with the same ANSI
   highlight sequence, but given we auto-page to less and less does not
   honour multi-line highlights only the command line summary was
   affectively highlighted. Rationale: for highlighting the description
   instead of the command line: the command line summary is relatively
   boring, and mostly the same for out tools, the description on the
   other hand is pregnant, important and captions the whole thing and
   hence deserves highlighting.

2. Always suffix "Options" with ":" in the help text

3. Rename "Flags" →  "Options" in one case

4. Move commands to the top in a few cases

5. add coloring to many more help pages

6. Unify on COMMAND instead of {COMMAND} in the command line summary.
   Some tools did it one way, others the other way. I am not sure what
   precisely {} is supposed to mean, that uppercasing doesn't, hence
   let's simplify and stick to the {}-less syntax

And minor other tweaks.

Zbigniew Jędrzejewski-Szmek 864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)
