Synopsis
========
This CR fix bug:  
(HLXSRV-361) Helix Server V.15 stops creating segments (.ts) files, if you access a \
live stream before the Minimum Playlist Segments reaches the stated value. \
(http://jira.real.com/browse/HLXSRV-361) (HLXSRV-470) Helix Server to create playlist \
long playlist for live-seeking with generic HLS media players. \
(http://jira.real.com/browse/HLXSRV-470) (HLXSRV-164) Request: Generate a M3U8 \
playlist file before minimum segment value reached. \
(http://jira.real.com/browse/HLXSRV-164)

Branch : HEAD

Suggested Reviewer : Anyone

Description
===========
Repro Steps: 
1. Install Helix Server v15.02 On rhel5 or Win2k8 R2 

2. Open the Helix Administrator. 
    Scroll to Media Delivery ->HLS Setup 
    Ensure that Enable Segmentation is set to Yes. 
    Select /broadcast/ under Edit Source Path -> 
    Ensure that Enable Source Path is set to Yes. 
    Under the Minimum Playlist Segments, enter a value of 60 

3. Create an SLTA stream, send it to the same Helix server you installed in step 1. 
     i.e. 
# ./slta.sh 192.168.127.14 80 admin Avaya live.mp4 meet.mp4 

4. Go to realserver/Segments/HLS_TS/broadcast/live.mp4, Watch the number of .ts files \
grow to between 15-30 .ts files. 

5. Open Safari via an iPad, iPhone or via Vlc media player, playback the live stream. \

Actual:
moving to bug

Expected:
- The .m3u8 file is created even if the number of .ts files in it are less than the \
                number configured in Minimum Playlist Segments
- The .ts files continue to be created,
- The player plays the live stream via HLS 

If for any reason this is not possible or too difficult to implement then an \
alternative acceptable result would be: 

- The .ts files continue to be created
- As long as the number of .ts files is less than the number configured in Minimum \
                Playlist Segments, the playback request is rejected with a 404 error \
                message. 
- When the number of .ts files reaches the number configured in Minimum Playlist \
Segments, an .m3u8 file is created and future playback requests are responded with \
                200 OK and a successful playback.  
- In no case the mere attempt to play back a stream that is "not ready yet" should \
stop the creation of .ts files or make the stream anyhow inaccessible. 

My solution:
Add input label "Maximum Playlist Segments" on HLS set up page to control total \
number of segments. When segments number reaches "Minimum Playlist Segments", \
generates .m3u8 file, and then continue to update this .m3u8 file after a segment is \
done. when segments number reaches "Maximum Playlist Segments", delete the oldest \
segments and update .m3u8 file when a new segment is done. If want to ENABLE HLS Time \
Shifting, we need to set "Maximum Playlist Segments" less than "Minimum Playlist \
Segments".
