Keyboard doesn't work with Qt 5.5

[Timo Jyrinki]

Possibly related to bug #1447190, the keyboard simply does not show when used with Qt 5.5 (no crash file created).

Qt 5.5 final is now testable on the phone, more information at https://wiki.ubuntu.com/Touch/QtTesting

maliit-server.log contents:

Since this affects being able to unlock the screen if passphrase is set, it's useful to know: gdbus call --session --dest com.canonical.UnityGreeter --object-path / --method com.canonical.UnityGreeter.HideGreeter

The QPlatformInputContextFactoryInterface_iid changed in Qt 5.5, however maliit had the string for this hard coded, resulting in the maliit plugin not being loaded inside applications. The attached patch fixes this, however I've also submitted this patch upstream and it's already been accepted so it might be worth using this as an opportunity to sync with upstream?

The patch will be included in the 012 PPA starting with a test build version number "0.99.0+git20130923+17fdf86-0ubuntu11~wily1~test4~qt550", although do note that because of the GCC5 transition now happening in wily archives it will probably take a good while now before the PPA is actually usable since all of Qt 5.5 will also need a rebuild. Anyway, once the GCC5 transition is completed annd PPA rebuild are done , the keyboard should then work which is great news!

Syncing with upstream in general, even before any Qt 5.5 landing is possible, sounds like a good idea.
