Template unit files (those with '@' in their names) are not handled with
native version of systemctl. This is usually not a problem, as the
native systemctl fails and systemctl command is executed during first
boot. But some early boot template units may fail during first boot
because opkg configure for first boot is pulled too late for them
(although I encouter it only with some of my services, not with oe-core
ones).

Handling of template unit files is same as in original systemctl. Also
DefaultInstance directive in template is respected. As with original
systemctl, enabling of template without instance and DefaultInstance
does nothing.

systemd has presets as described here

http://lists.freedesktop.org/archives/systemd-devel/2011-July/002830.html

This patch will let distros define presets file
which will override the enable/disable specified
by recipes.

systemctl preset without any argument will run presents
on all services

systemctl preset service1 service2 will run presets on
specified pervice.

something like enable * or disable *
would mean that all services will be either enabled or
disabled by default.

If no user-presets are specified then 'enable' is default

systemd allows basic globs but we do not implement them
except '*'

The Alias and WantedBy directives can accept all valid unit types when
using the systemctl from systemd. And since the systemctl script should
match the behavior of systemd as much as possible, add the current set
of unit types listed at
http://www.freedesktop.org/software/systemd/man/systemd.unit.html
to the Alias and WantedBy directives.

The deficiency was exposed when trying to use:
    Alias=default.target
in a foo.target. No symlink was created by running
"systemctl enable foo.target" during the package's postinst.

Old script failed to parse unit files containing comments like

| #Alias=some-alias

or whitespaces like

| WantedBy = foo

correctly.  Patch changes script to interpret keywords only when they
are at the beginning of a line and ignores whitespaces before the '='.

Add systemd recipes and associated support recipes.
