fact that unit files can be specified as unit file paths, not unit
file names, wrongly passing a unit file path to the 1st argument of
manager_load_unit() that handles it as a unit file name. As a result,
the following 4 systemctl subcommands:

    enable
    disable
    reenable
    link
    mask
    unmask

fail with the following error message:

    # systemctl enable /usr/lib/systemd/system/kdump.service

To fix the issue, first check whether a unit file is passed as a unit
file name or a unit file path, and then pass the unit file to the
appropreate argument of manager_load_unit().

By the way, even with this commit mask and unmask reject unit file
paths as follows and this is a correct behavior:

    # systemctl mask /usr/lib/systemd/system/kdump.service
    Failed to execute operation: Invalid argument
    # systemctl unmask /usr/lib/systemd/system/kdump.service

sd-bus: introduce new match type "arg0has=" for matching arrays of strings

Previously, sd-bus inofficially already supported bus matches that
tested a string against an array of strings ("as"). This was done via an
enhanced way to interpret "arg0=" matches. This is problematic however,
since clients have no way to determine if their respective
implementation understood strv matches or not, thus allowing invalid
matches to be installed without a way to detect that.

This patch changes the logic to only allow such matches with a new
"arg0has=" syntax. This has the benefit that non-conforming
implementations will return a parse error and a client application may
thus efficiently detect support for the match type.

Matches of this type are useful for "udev"-like systems that "tag" objects
with a number of strings, and clients need to be able to match against
any of these "tags".

The name "has" takes inspiration from Python's ".has_key()" construct.

Prior to commit c32eb440bab953a0169cd207dfef5cad16dfb340, libudev's
function udev_enumerate_scan_devices() had behaved differently. If
parent match was added with udev_enumerate_add_match_parent(),
udev_enumerate_scan_devices() did not return error if some child devices
had no subsystem symlink in sysfs. An example of such devices is USB
endpoints /sys/bus/usb/devices/*/ep_*. If there was a parent match
against USB device, old implementation of udev_enumerate_scan_devices()
did not treat ep_* device directories without subsystem symlink as error
and just ignored them, but new implementation returns -ENOENT (also
ignoring these devices) though correctly enumerates all other matching
devices.

To compare, you could look at 96df036fe3d25525a44f5efdb2fc8560e82e6cfd,
in src/libudev/libudev-enumerate.c, function parent_add_child():

    if (!match_subsystem(enumerate, udev_device_get_subsystem(dev)))
            goto nomatch;

udev_device_get_subsystem() was returning NULL, match_subsystem() was
returning false, and USB endpoint device was ignored.

New parent_add_child() from src/libsystemd/sd-device/device-enumerator.c
checks return value of sd_device_get_subsystem() and fails if subsystem
was not found. Absence of subsystem symlink should not be really treated
as error because all enumerations of children of USB devices will fail
with -ENOENT. This new behavior also breaks system-config-printer.

So restore old behavior and treat absence of subsystem symlink as no
match.
