7e343b530e meson: Generate fuzzer inputs with directives 
The lists of directives for fuzzer tests are maintained manually in the
repo. There is a tools/check-directives.sh script that runs during test
phase and reports stale directive lists.
Let's rework the script into a generator so that these directive files
are created on-the-flight and needn't be updated whenever a unit file
directives change. The scripts is rewritten in Python to get rid of gawk
dependency and each generated file is a separate meson target so that
incremental builds refresh what is just necessary (and parallelize
(negligible)).

Note: test/fuzz/fuzz-unit-file/directives-all.slice is kept since there
is not automated way to generate it (it is not covered by the check
script neither).

a5398c774b fuzz: rename test cases for brevity and meaning 
Those long indentifiers make test output very wide, and they are ultimately
not very useful for humans to look at. Let's use some short string to identify
the test failure instead.

ec4954d934 network: rename netdev kind virtual-wlan -> wlan 
The Kind= setting in [Match] section of .network files takes "wlan".
This makes the same setting in .netdev files matches the one in .network
files.

cbcdcaaa0e Add support for conditions on the machines firmware 
This allows to limit units to machines that run on a certain firmware
type. For device tree defined machines checking against the machine's
compatible is also possible.

0d0de133f0 network: add support for MACVLAN source mode 
Add support for creating a MACVLAN interface in "source" mode by
specifying Mode=source in the [MACVLAN] section of a .netdev file.

A list of allowed MAC addresses for the corresponding MACVLAN can also
be specified with the SourceMACAddress= option of the [MACVLAN] section.

An example .netdev file:

    [NetDev]
    Name=macvlan0
    Kind=macvlan
    MACAddress=02:DE:AD:BE:EF:00

    [MACVLAN]
    Mode=source
    SourceMACAddress=02:AB:AB:AB:AB:01 02:CD:CD:CD:CD:01
    SourceMACAddress=02:EF:EF:EF:EF:01

The same keys can also be specified in [MACVTAP] for MACVTAP kinds of
interfaces, with the same semantics.
