[vlc-devel] [PATCH] Reshuffle after playthrough

there is no simple way to check whether all elements have been played, it
would require me keep track of everything as well as managing adding /
removing elements from the playlist.

my patch does the following: when the NextItem function is invoked as
result of automatically advancing. it checks if the last element has been
played and if so: shuffles the playlist and restarts with element 0.

when using the next button the NextItem function works different. instead
of simply increment i_current_index it uses the p_sys->request mechanism to
figure out which element to play next. firstly i am afraid of breaking
stuff when i alter the code to much (i'm not very familiar with the source
code). secondly when i add shuffle the same way i did on the other part,
there won't be a guarantee every element is played once before shuffling

reason: NextItem gets told which element to play next. if i reshuffle the
playlist this next element which should be played might not be the first
element of the new order, hence some elements are not played before the
last one is reached.
if i override the element request in any way i might break the whole
request mechanism.
