{lib}mediainfo{-gui}: 0.7.84 -> 0.7.86

From the changelog:
```
Version 0.7.86, 2016-05-31

+ Linux/Mac: more output formats (PBCore, EBUCore, FIMS)
+ FFV1 parsing optimization, avoiding by default a too verbose trace
+ Matroska: more elements support and typo fixes in the trace
+ #I172, Trace feature: provide the name of the main parser in the media element
+ Matroska: consider all values below 0x10 EBML names as 1-byte junk
x Matroska: better support (including speed improvement) of huge lossless frames (e.g. 20 MB FFV1 4K)
x #I144, Python binding: Python 2 on Linux does not automatically provide the locale to the shared object
x HTML output: don't escape carriage returns from the input file
x FFV1: some streams were rejected despite the fact they are valid
x Python binding: some errors during call of Get() API with Python3 on Linux/Mac
