When sharing URLs through KDE Connect, the incoming "url" usually contains some
additional description that was added by the source application. Use regext to
pick up any valid http[s] URLs that may be found in the text.

drop autotools, use meson exclusively

TLS support

Fingerprint is avaialble as CertificateFingerprint property, the format is the
same as produced by GnuTLS' certtool, eg:

   sha1:d7860c6978d714e9e8f9805065602ea14e295df9

mconnect's certificate is accessible as Certificate property of
org.mconnect.DeviceManager interface on /org/mconnect/manager object.

Display device certificate when running show-device in verbose mode. To
introspect the certificate run the following:

    mconnectctl show-device --verbose /org/mconnect/device/0 | \
      certtool -i

Previous version of mconnect did not have a 'certificate' key in device section.
When loading such device do not fail instantly but rather log a warning and let
the loading continue further.

Glib TLS support is required to run some of the tests
