[gsupplicant] Add interface EAP signal. Contributes to: JB#48582

See merge request !8

The EAP signal from wpa_supplicant Interface provides more detailed
information about the EAP handshake and can be used to better deduce
error types.

[gsupplicant] Allow private key without client cert. Contributes to JB#48581

See merge request !7

Allow definition of network with private_key set, but client_cert not
set, as this is the format wpa_supplicant expects PKCS#12 bundles to be
used. Reject requests with client_cert but no private_key.

Plug GSupplicant reference leak

See merge request !6

[gsupplicant] Clear only blobs that are being set. Contributes to JB#45980

Compatibility with glib 2.56

See merge request !3

Handle "notify" instead of "g-properties-changed". It's advertised
by glib docs as the right way of doing it.

If the stubs are generated by gdbus-codegen < 2.56 then strv getters
return shallow copy, i.e. the return result should be released with
g_free(), but the individual strings must not be modified. Luckily,
this can be determined at compile time.

See https://bugzilla.gnome.org/show_bug.cgi?id=770335

Don't rely on gutil_types.h to pull it in.

Maintain the list of connected stations

See merge request !2

This adds 'stations' field to GSupplicantInterface

This is primarily to make gsupplicant_util.h gio-free

Treat SSIDs consisting of all zeros as empty

See merge request !1
