Patch by Richard Hosking: Userptr IO buffers need to be aligned according to the V4L2 reference capture c example (which has been updated with this recently). Also, the reference program has the device close operations after the 'free' calls so they have been moved. This fixes the issue I was having with my device crashing vlc on close. Also fixed a typo in an error message and renamed a local function which was badly named by me. 

vlc_intf_strings.h: with the current intf having changing icons on the button (and not activated/desactivated state), tool tips can be confusing. So reword a strings slightly. Also "No repeat" may need to be improve

Qt4 - fix the assert bug on releasing the Video. There are other to do, but I don't have time this WE, but here is the way to do it correctly.
funman ? :D

btw, faad2.6 is out and they have supposedly changed their headers...

Now, the synthetizer is "pinged" at regular interval.
This fixes the annoying stuttering when two consecutive notes where too distant

ncurses: ressuscite file browser, and 'A' key (add an entry) with support for media library\nchecks vasprintf() return value

playlist/services_discovery.c: Isolate more the services_discovery code from the playlist code by having two separate header. Partly revert [22536].

playlist/services_discovery.c: Attempt at removing also node as well as regular items. Need some testing with the hal services_discovery module.
