pvr: Pass selected item to menu hooks

Currently it is not possible to retrieve any information about the
selected item in the addon's menu hook callback. Therefore menu
hooks can only trigger actions per category, but not per item.

This patch removes this limitation by extending CallMenuHook with
an item parameter representing the type (PVR_MENUHOOK_CAT) and the
data of the currently selected item. The type PVR_MENUHOOK_UNKNOWN
indicates that no selection is available (as for settings hooks).

[DVDPlayer/Subs] Save the subtitle number at the end of the OpenSubtitleStream() method.
Regardless of whether the subtitle has been opened successfully or not.
[GuiDialog/PlayerControls] Use CMediaSettings::Get().GetCurrentVideoSettings().m_SubtitleStream instead of g_application.m_pPlayer->GetSubtitle().
The latter one returns the maximal index if the current subtitle could not be opened. This yields wrong info about the subtitle.

[rbp/omxplayer] Simplify clock handling

In OMXClock we have an almost complete copy of DVDClock, so just use DVDClock directly.

The passing through of CDVDClock functions from OMXClock is hopefully temporary,
as I think clock manipulation is better handled from OMXPlayer than audio/video players.
