(Oh! another ABI break - if only vlc_input_item_t weren't public)

The input already does the job.

(see MRLSplit), so this has become useless, if not inconsistent.

input/input.c: Misformatted if statement fix. Could someone check if that's really the wanted behaviour though. 

misc/objects.c: Don't rely on vlc_object_destroy() to destroy objects, but expects vlc_object_release to do it when the refcount goes to zero.
* Meaning, that when created objects gets a refcount to 1.
* Destroying is instantaneous and we don't have to poll for a few secondss or so to wait until the object's refcount reach 0.
* We now track vlc_object_t's mem leaks when libvlc_global is released (Hard error for now, so they don't get unoticed)
* We fail hard if an object is released with a refcount of 1 without being detached from its parent and its children, to make sure such cases don't go unoticed.
(make test or make check still pass after that one. VLC is known to leak one object when no module is loaded, this must be fixed).

qt4-interface to use it. var_Change doesn't trigger callback so earlier
version about adding callback to it worked someway as intented only by
luck ;)

This fixes opening file names with colons which some users,
at the expense of requiring "://" to separate the access from the path.
As such udp:@12.34.56.87 won't work anymore, use udp://@12.34.56.87 instead.

 It fixes errors when using mapped file input (for example with asf,
or with truncated files)
 Please, report any regression (with dvb, mapped file, v4l, mms inputs)

removes unused arguments

Missing some cases that I could not test.
Also ffmpeg/chroma.c is locked, so I can but leave it broken.
Fix is for the remaining modules is obvious and the issue is easy to detect.

input/meta.c: Don't re-run the art finder if the art was previously set in input_ArtFind. (Should fix youtube.lua arturl).

input/input.c: Define DEMUX_CAN_SEEK and correctly set "seekable" accordingly. (This could introduce regression such as seekable item no more seekable, but I should have greped enough...).
