Zbigniew Jędrzejewski-Szmek 8458ca26c1 networkd: reword debug messages 
"left from <something>" is not correct. "left <something>" would be the
usual form, but "left master interface" is not clear at all. So reword
those messages totally.

Follow-up for 3881fd406b.

Yu Watanabe b732606950 network: automatically determine timeout of waiting for carrier regain 
The commit 6706ce2fd2 made
IgnoreCarrierLoss= setting also take timespan, to make users handle
issues like #18738 or #20887. But still users needed to explicitly set
a timespan.

This makes networkd automatically determine the timeout when the
situations #18738 or #19832 is detected. Unfortunately, still users have
issue #20887 need to specify a value.

Closes #19832.

Lennart Poettering ba4e0427e9 time-util: assume CLOCK_BOOTTIME always exists 
Let's raise our supported baseline a bit: CLOCK_BOOTTIME started to work
with timerfd in kernel 3.15 (i.e. back in 2014), let's require support
for it now.

This will raise our baseline only modestly from 3.13 → 3.15.

Yu Watanabe e26d3d407c network: make Request object take Manager* 
Previously, even though all Request object are owned by Manager, they
do not have direct reference to Manager, but through Link or NetDev
object. But, as Link or NetDev can be NULL, we need to conditionalize
how to access Manager from Request with the type of the request.
This makes the way simpler, as now Request object has direct reference
to Manager.

This also rename request_drop() -> request_detach(), as in the previous
commit, the reference counter is introduced, so even if a reference of
a Request object from Manager is dropped, the object may still alive.
The naming `request_drop()` sounds the object will freed by the
function. But it may not. And `request_detach()` suggests the object
will not be managed by Manager any more, and I think it is more
appropreate.

This is just a cleanup, and should not change any behavior.

Yu Watanabe b1d9c504d3 network: wait until the DSA master interface becomes up 
This is for the DSA subsystem, which have several stacked interfaces
on the master interface. To bring up a stacked interface, it is necessary
that the master is already up. See
https://github.com/systemd/systemd/issues/7478#issuecomment-348508263.

Note this is not necessary for newer kernels which includes
https://github.com/torvalds/linux/commit/9d5ef190e5615a7b63af89f88c4106a5bc127974.

Fixes #7478.

Yu Watanabe 71df07760e network: sd-ipv4ll and sd-ipv4acd only support ethernet interfaces 
The deny list in link_ipv4ll_enabled() are mostly non-ethernet type,
whose link->iftype are not ARPHRD_ETHER, e.g. ARPHRD_NONE for bareudp,
ARPHRD_WIREGURAD for wireguard, ARPHRD_GRE for gre, and so on.

Only the exception is vrf, which is ARPHRD_ETHER, but seems not to
support ARP.

Yu Watanabe 879377cad5 network: do not block configuring addresses by creating stacked netdevs
