When a worker receives both a signal and a udev event in the same epoll_wait
run, the event must be processed first because the udev parent considers the
event already dispatched. If we process the signal first and exit, udevd
times out after 60 seconds waiting for a response from an already-dead
worker.

On some systems the list of units in systemctl output came out wrong,
all on one line and with missing descriptions.
It turns out printf() really attempts to mmap 2G memory when INT_MAX is
passed as the field width. On machines with small virtual memory
without overcommit the mmap inside printf() failed.
Do not use INT_MAX for unlimited width.
KEYMAP are use to pass keymap configuration to initrd, but not to the
system itself. Since the initrd might get out of date we need to make
sure that changes made in userspace override the settings from the
cmdline, hence drpo any use of it all for these variables.
Provide nicer output by taking advantage of the available columns.
Expand UNIT and DESCRIPTION if possible. Economize the space:
- never give UNIT more width than it can use.
- if there's a shortage of space, give 25 columns to UNIT, even
if it would result in overflowing the total columns. The field would not
be useful below width 25.
- then if possible, assign up to 25 columns to DESCRIPTION.
- then split any remaining space evenly between UNIT and DESCRIPTION.
Keep the columns aligned even with '--full'.
Print the legend (the column headers and the footer with hints) by
default even to non-tty output. People seem to get confused by the
difference when they redirect the output.
Add a parameter to suppress the printing of the legend.

In the very unlikely scenario where none of the external pagers is
available, use an internal implementation to pass stdin to stdout.
Don't bother with trying 'cat', because it's no more useful than the
internal pager.

In situations like this:
root@omap4430-panda:~# systemd-analyze
Startup finished in 1499ms (kernel) + 916ms (userspace) = 2416ms
The svg plot will only have the 0s marker and no subsequent markers for scale. This patch forces the 1s marker to always be drawn.
'man systemd.target' says:
Unless DefaultDependencies= is set to false, target units will
implicitly complement all configured dependencies of type
Wants=, Requires=, RequiresOverridable= with dependencies of type
After= if the units in question also have DefaultDependencies=true.
It did not work because of a forgotten negation.
