* modules/video_filter/deinterlace.c: fixed aspect-ratio + pass on cropping info (could be optimized to only deinterlace cropped part).

 * if --sout-rtp-ttl=0  use --ttl for c= line

different ttl each.
Need to re-think relations with --ttl and SAP within #404

In any case, that's ugly and thread-safe. The proper solution would
be to reimplement an atof() version that is locale-independant and
use in the many places that expect C/American float numbers. Even
then, there might be some buggy underlying libraries breakage
(e.g. Live555 ?).

Tested on Linux (both UTF-8 and Latin-x locales).
Needs testing on Win32.

I'm not explaining this again.

(fixes #406)

For absolute path use ftp://foo.bar//usr/local/etc/filename
-This line, and those below, will be ignored--

M    modules/access/ftp.c

(this command does nothing at the moment ;)

 * for RTP, prebuffering is done within RTP access
 * reordering now working within this buffer
 * solves synchro problems since packet rate is preserved 

by a simple click (was a double click before) which is more
natural

 (at the moment the tree control is still entirely rebuilt,
 but now it will be easier to fix that)
 + coding style fixes

 (was broken for quite a long time...)
* ctrl_tree.cpp: removed debug messages

Hosts should never send packets with TTL=0

psz_uri is NEEDED - it determines the destination for SAP announces

* modules/video_output/x11/xcommon.c: support cropping to i_visible_width/height in xvideo (not implemented in x11 yet).

* src/video_output/video_output.c: get rid of hack for for grey line with hdtv streams (proper way is to have video outputs support cropping to i_visible_width/height).

* src/video_output/vout_pictures.c: use fmt_in.i_visible_width/height and i_sar_num/den in vout_PlacePicture().
