#7339 new enhancement

HLS-Retry mechanism for HTTP-Upload segments

Summary of the enhancement:
Retry hls-segment upload once, if web server returns HTTP 500.
How to reproduce:

% ffmpeg -i -ar 48000 -c:a libfdk_aac -b:a 128k -f hls -hls_time 2 -method PUT -hls_segment_filename '' -master_pl_name 'master.m3u8' -timeout 2 '' -loglevel trace
ffmpeg version n4.0.1
built on ubuntu 16.04

First I thought I can just rerun „ff_http_do_new_request“ if result shows failed state
But function does NOT return any errors, if webserver returns HTTP 500.

„ff_http_do_new_request“ refers to -> „http_open_cnx“
I thought that I can extend handling for http_code 30x for http_code 500, but function „http_open_cnx_internal“ did never return this code, though web server did (see 1.)

„http_open_cnx“ refers to -> „http_open_cnx_internal“ refers to -> „http_connect“.

Here this function returns ALWAYS http_code 200 for posting data.

Function „http_read_header“ will NEVER be executed.
