[patch][bugfix]Http mp4: replace strtod() with improved ngx_atofp() because precision problem.

[胡聪 (hucc)]

Hi, all
I've sent a patch.
http://mailman.nginx.org/pipermail/nginx-devel/2016-October/008932.html
that solves precision problem of ngx_http_mp4_module. 
Did any one noticed this patch.


Downstream cache system receives duplicate data by sending start&end parameters which are analyzed from moov box and aligned with the GOP. PotPlayer becomes not fluent when playing hls stream which is converted from the mp4 (duplicate data). Nginx can not quietly change the parameter value, and send non-requested data to clients or player. 


So the patch is helpful.


Regards,
-hucc
