If you setSortingEnabled after setting model, it doesn't call sorting,
otherway around it does. Missed thatone on previous try.

(Cherry-picked from commit 28b4ac7c)

This should be more clearer to user what column is used to sort (eg if
it's hidden, then hide sortIndicator also).

macosx: prepare the switch from dyld to 'Dynamic Loader Compatibility Functions' as partially intended by [7147338b]

Using Apple's legacy object file image functions around NSModule is strongly discouraged and won't work in the future at all.

This reverts commit 7147338b.

it checks table of frequencies that usually contains channels. Thou
dvb-c users need to check if modulation and symbol-rate are correct for
them (atleast for me modulation auto didn't work).

example commandline that worked for me:
vlc dvb:// --dvb-srate=6875000 --dvb-modulation 128

Thisway playlist don't run sort when created (in case of you start vlc,
and don't set playlist visible then adding stuff. When you open playlist
it would sort the stuff).

Also remove showing sort-indicator incorrectly on start (don't show
it at all before user clicks to sort).

It is a manual backport of:
- [9b8c543c] Subtitles accuracy
- [9c462ffb] Ephemere destruction
- [fabf2399] Fixes for previous commits

It does not changes existing functions, but add 2 new ones.

Now seeking and skipping behave exactly the same.
It also allows forward seeking in non seekable stream by reading the data.
It closes #2994.
As it is a critical section of code, it must be carefully tested.

This will still assert in debug build due to a core bug

EXTRA_DATA doesn't seem to be a "primary" even if DATA is and EXTRA is a valid prefix.
Also i don't think .vlt are often rebuilt so it should be in clean rather than mostly clean

dialog_ProgressCreate can return NULL. For this case,
only deal with the result if it is not NULL.
