There was a lot of repeated code, some of which properly checked return
values and some of which didn't.  This is all replaced and folded into
the GetProperty function of each interface.

A side-effect is that it should be more efficient (we only check the
interface argument once instead of once for each property, and there
should be a smaller overall code size).

Pull out code to marshal the various properties into separate functions
(and make sure the return type of those functions is int).  This is in
preparation for adding org.freedesktop.DBus.Properties.GetAll support.

Re-use the AddProperty method (used in GetAllProperties) and use macros
to reduce repetition of code.  Now all the calls should be
error-checked.

 * Add missing call to vlc_object_release() in MarshalMetadata
 * Separate code paths with empty lines
 * Fix bracket position in if blocks

VLC was getting kicked from the D-Bus when a track was stopped, because
it was generating invalid data on the wire when sending the
PropertiesChanged signal for the Metadata property.

The issue was that if there was now no current track, GetInputMeta would
never be called and the the variant would never be populated with the
"a{sv}" structure that the call to dbus_message_iter_open_container
claimed it would be.

We now share the code that GetProperties used, which dealt with this
correctly, although now both use CurrentInput (which is what the signal
previously used) instead of CurrentPlayingItem (which is what
GetProperties previously used).

Rate should never be 0.0 (according to the spec), so we pick a sensible
default when we do not have a current track: 1.0.

Also, when the current item changes, the Rate may also change.  So add
it to the PropertiesChanged signal just to be sure.

Several of these entries, such as xesam:artist, should be lists of
strings, not strings.

Previously, Fullscreen could be requested via
org.freedesktop.DBus.Properties.Get, but would not be returned by
org.freedesktop.DBus.Properties.GetAll.

This is in preparation for implementing GetAllProperties for the player
and tracklist interfaces.

This is the right place to make sure an art file that was not available at
input launch time gets a chance to be displayed as soon as it becomes available.

When MP4_ReadBoxContainerChildren() returns, one expects the position in
the stream to be that of the next box after the last parsed box.

Without this very patch, if the last parsed box is an "unknown" one,
the position in the stream would be at the begining of that box,
preventing playback of latest Anevia's MS Smooth Streaming live streams,
for example.

Since non-ASCII or non-printable characters are not supposed to occur
in URL, it does not matter much how they are dealt with.

The caller of decode_URI() can anyway not assume anything about the
decoded string. In particular, decode_URI() does not validate UTF-8
sequences in any case.

When changing a skin theme on the fly, an input may already be running
 and the art file is expected to display in the new theme.

This patch takes into account a possible art file already kwown
at initialisation of a new image control with art enabled.

Art display used to rely on an event issued by vlc core which has been renamed into "activity" lately. The issue was that it seems no longer fired when a new
 input is launched.

A relative jump of +1 is the same than 0, we need +2 to skip the next
instruction.
Use named label so it is more clear than +2.

Read the InstallDir regkey, "" points to vlc.exe

Mpeg-4, H.264, VP8 and other deadlocks with -mt have been fixed
and fuzzed by Janne, notably, since a few weeks/months.

That future version is expected to remove a number of already
deprecated interfaces, such as CODEC_ID_* or the Snow codec.
VLC still uses these interfaces as of today.
