worst until we completly switch to demux2...)

 * livedotcom, mkv: removed all TAB_*.

 from stable, but begin to work. (Tested only with TS).
 Limitation: no synchro with others stream if any (anyway, it would be
a bit stupid to have such stream).
 

Found and fixed:
- some untranslated macros
- some acronyms which were not in capital letters
- a couple of VLC Media Player (_m_edia _p_layer, now)
- typos here and there
- dots missing in some of the long texts
- spaces before ? and :, which is correct in french but not in english :)
- NT services are now called Windows Services

 using weird value after a synch with RTCP.

* modules/demux/livedotcom.cpp: compilation fix.

* include/vlc_common.h: include stdlib.h
* include/ninput.h, src/input/stream.c, src/input/input.c:
    new stream_Block() function to read a block_t from the input.
    es_out_Send() takes a block_t as input, for PES (deprecated) use es_out_SendPES().
* modules/demux/*: changed to new es_out_Send(). asf.c and avi.c still use es_out_SendPES() though.

 * more verbose header parsing code
 * support for compressed announces if zlib is available (using some code
   from Mosu from the matroska project)
 * if the sdp packet contains more than one m= line, pass it to the
   livedotcom module
configure.ac:
 * link sap with zlib if available
modules/demux/livedotcom.c:
 * accept sdp from the sap module

 all: removed i_extra_type from es_format_t.

* ALL: final improvements to the decoders/packetizers api.
   (There are still a few decoders/packetizers left to be converted but this shouldn't take too long).
* ALL: small improvements to the encoders api.

    - added X-QT and X-QUICKTIME video support.
    - first try for seek and position display support.
    (position is buggy, and seek won't really work as long as wx try to seek
    each time the slider is moved)

* configure.aci, modules/demux/livedotcom.cpp: win32 compilation fixes.

    - improve a lot pts handling.
    - added --rtsp-caching.
    - implemented DEMUX_GET_TIME  and declared the input as seekable to
    make the interface displaying the time.
 Now I can read rtp stream from VLC using http export for sdp :) (MPEG4
video, MPEG 1/2 video and mp3 audio tested successfully)

 over tcp doesn't really work yet).
                   - fixed bad usage of delete vs delete[]
(using --rtsp-tcp still leads to segfault)

 lot of mandatory fields missing, like v, o, and s)

    TODO:
        - handle PTS (for now, I just use mdate() :)
        - support TS/PS (hard as it needs a lot of work on TS/PS demuxers).
        - support X-QT and X-QUICKTIME. (I don't know if it's really used).
        - implement pause, seek ...
        - clean up/bugs fixes...
        - ...
