* Add --list-verbose option.
* Make sure that help related options always come first in the help output.

Modules have a psz_help string. This is currently used by 1 module only (headphone audio filter) ... but that doesn't mean that it shouldn't be stored in cache. This commit will break the cache so we need to change a cache version somewhere. Since i didn't know where to look ... this is yet to be done.
+ misc changes

Adds one instance in NEWS

I thought the comments where pretty clear.

(disk full?)

* Core: add var_Command function. This is used to execute a command registered on a object with a given name.
* rc.c: use var_Command (instead of own code)
* telnet.c: add support for object commands (like in the rc interface)

Allow changing the subpicture filter chain at runtime. (This currently kind of segfaults some of the time (after 2 changes) ... somemore bughunting is needed)

vout_subpictures.c: enable scaling for RGBA subpictures.

vout_subpictures.c: Do not call the scaling module if the subpicture is using RGBA. The current way subpictures scaling and blending modules loading work is kind of flawed. It assumes that the module will be able to handle all the possible types of input chromas. This worked fine previously (since all modules allowing to scale/blend YUVP also handled YUVA), but doesn't now (the scaling module doesn't support RGBA. blending works fine).
vout_pictures.*: Add core support for RGBA pictures.

- libvlc: new libvlc_video_redraw_rectangle() API, this allows caller to tell vout to redraw part of video, vout needs to implement VOUT_REDRAW_RECT message to support this

- getaddrinfo.c : cleanup replacement APIs for win32 and make sure the shim logic only searches for real APIs only once

- control/input.c: don't rely on exceptions to control the state of API internal logic as these are optional
