Fix for url bug in the qmlvideo examples.

In the FileBrowser paths where being prepended with file:///, since all
the paths already starts with a forward slash, navigating away from the
initial directory was therefore not possible.

To make the examples work on Android, QT += multimedia was added.

Android: Fix for uncaught java exception.

If an exception's getMessage() function returns a null object, we can't
send it directly to the Log function, as it will throw an exception...
To avoid this we can prepend the string from getMessage() with an empty
string.

Multimedia plugins now have a unique JSON metadata 'Keys' property.

They previously had the multimedia services they provided as keys. This
was a problem when several plugins were available on the same platform,
providing the same multimedia service, but with different features or
capabilities. Since they had the same key, only the first plugin in the
directory was loaded.

Nevertheless, it was actually working until commit 732dcfe7 in qtbase,
as all plugins were loaded even when sharing the same key.

The services a multimedia plugin provides are now declared in the
'Services' property. To preserve compatibility with third-party plugins,
if that new property doesn't exist it falls back to the 'Keys' property.

Use correct default audio output and input devices on Windows.

It was returning the first available device as the default, which might
not be the actual default device. Use the WAVE_MAPPER device ID instead
that tells Windows to use the most appropriate device.
