format version to prevent it from being used with older versions.

libobs: Fix circlebuf_pop_back returning front

On Linux the preview widget scaling uses only the integer part of the
scale. This results in a partially non-repainting window that looks
buggy and annoying.

UI: Revert default tab in Settings > Output: Advanced tab to Stream tab

Commit 2fedcab9 changed the default index for widget "advOutTabs"
in OBSBasicSettings.ui; revert to index 0 (stream tab).

rtmp-services: Remove dead servers/services

Closes obsproject/obs-studio#1563

A mono input with surround output is upmixed by swresampler by routing
it to FC (front center) by default which corresponds to third channel
for 3.0, 4.0, 4.1, 5.0, 5.1, 7.1. (The other channels are muted.)
But the volume meters are set to show the first channel for mono sources.
Therefore although audio is processed, it would not show on the meter.
This fixes this display issue.
