basic: add minimalistic table formatter

console, and all is homegrown and awful. Let's replace it with a generic
implementation that can do automatically what the old implementations
did manually.

Features:

1. Ellipsation (for fields overly long) and alignment (for
   fields overly short)

2. Sorting of rows

3. automatically copies formatting from the same cell in the row above

4. Heavy use of varargs to make putting together tables easy

5. can expand and compress tables, with weights

6. Has a minimal understanding of unicode wide characters in order to
   match unicode strings to character cell terminals.

7. Columns can be reordered and individually turned off.

8. pretty printing for various data types

And more.

   result strings won't show too much info still of course, but the code
   becomes a bit more generic and robust to use.

2. If a UTF-8 mode is disabled and the input string is pure ASCII, then
   "..." is used for ellipsation, otherwise (as before) "…". This means

   behaviour otherwise exposed with special_glyph() and friends. Note

networkd: fix dhcp4 link without routes not being considered ready (#8728)

The dhcp4 code sets link->dhcp4_configured when dhcp4_route_handler()
has processed the last message.

However, in case UseRoutes=no has been set in the [DHCP] section, or
in case the DHCP server simply sends no routes, link_set_dhcp_routes()
will not send any netlink messages and dhcp4_route_handler() will
therefore never be called.

This causes the link to never reach LINK_STATE_CONFIGURED, and e.g.
systemd-networkd-wait-online will not consider the link as ready.

Fix that by setting link->dhcp4_configured = true and calling
link_check_ready() in dhcp4_address_handler() in case
link_set_dhcp_routes() sent no netlink messages (dhcp4_messages is
zero).

Lennart Poettering [Fri, 23 Feb 2018 11:32:23 +0000 (12:32 +0100)]
dropin: when looking for dropins for a unit, also look within "-" prefix unit dirs

This extends the logic by which we look for drop-ins for unit files when
loading them. Previously for a unit "foo-quux-bar.service" we'd look in
a directory "foo-quux-bar.service.d" accompanying it for extension
dropins. With this change we'll additionally look in:
"foo-quux-.service.d" and "foo-.service.d", i.e. we'll truncate the unit
name after every dash.

This is an alternative to templating for many services, as it permits
configuring defaults for sets of units that all use the same prefix in
the unit name. This is particularly useful in slice, mount and
automount units which reflect a hierarchy of concepts, as it permits
setting defaults for specific subsets of the tree. For example, in order
to provide every user with a memory of 1G it's now possible to do:

    # mkdir -p /etc/systemd/system/user-.slice.d
    # cat > /etc/systemd/system/user-.slice.d/50-memory.conf << EOF
    [Slice]
    MemoryMax=1G
    EOF
    # systemctl daemon-reload

This makes use of the fact that every user gets his own slice unit when
logging in, named "user-$UID.slice".

This doesn't precisely provide what is requested in #2556, but it does
provide equivalent functionality.
