Added missings realloc/malloc checks.
Added support for not closed html tags (only if missing at the end).

It is not yet used, but will allow CD-TEXT info support.

This might fix the X_GLXCreateWindow BadMatch error. I cannot reproduce
it, so I cannot confirm this.

glXChooseFBConfig always return NULL if there are no adequate configs.

(still a big problem with callbacks that execute an action directly)

3 options:
- Mousewheel x -> volume && y -> position
- Mousewheel x -> position && y -> volume
- Mousewheel ignored

I think this is not optimal, but it should do it for the VLC 1.0.0-release,
after that, we will see with the multiple-hotkeys development...

This seems to trigger a pseudo-random native failure. Most likely a
critical bug in the VLC meta support.
