RTMP authentication requires the curStreamIdx and nStreams be set
between the disconnect / reconnect that occurs in PublisherAuth. Now
that there's no good place to clean them up, zero the whole rtmp->Link
before starting a new stream.

win-capture: Fix format string warning

libobs: Only manipulate input source ref counts

win-capture: Handle NULL VkApplicationInfo

UI: Fix scenes as sources for SL import

Filters can be hidden without being shown, which can unbalance the ref
count and destroys them prematurely. We really only care about input
sources having a chance to clean up from the render thread from the hide
handler, Windows 10 window capture specifically.

UI: Fix override transition not working

UI: Do not disable t-bar

The previous fix for repeated names accidentally meant that if a scene
item in a scene was meant to show another scene that was lower in the
list, it would fail to create the item, and wouldn't make it into the
imported collection.

This fix makes sure that scenes as sources still works properly in that
situation.

Closes obsproject/obs-studio#2448

In window capture, it will search for a window with a specific title,
but will not search minimized windows.  This fixes that by making is
acquire the correct window even if that window is minimized, rather than
potentially risk it capturing the wrong window of the same type.

obs-ffmpeg: Fix some incorrect settings for srt output

This fixes some configuration parameters which were incorrect (for audio).

UI: Fix importing SL collections with repeated names

For some reason this has a noticeable performance improvement,
presumably because Qt is notifying all the child widgets?

Fixes a CEF initialization issue where CefInitialize would internally
call a Chromium function that would change process permissions.  The
permissions it changed would break other functionality within the
program, such as the new window capture method based upon
Window.Graphics.Capture.

UI: Dynamically set widget index when renaming sources

CMake: Disable incremental linking on Windows

Not compatible with /OPT:REF, and caused warnings.

When "Automatic" was added, the index for the item that needed to be
disabled became incorrect (to disable WCG).

CMake: Enable /OPT:REF for Windows

This ensures that the OBSBasicSettings destructor has been run before
the restart prompt appears, preventing bugs related to OBS shutting down
with the settings window still having active callbacks.

This can be fired by a callback during source removal. The code was
re-adding the source that was just removed, causing the program to
freeze when trying to remove all sources.

Sources may be removed or destroyed by other threads which resulted in
GUI calls outside of the main Qt thread.
