Updates include:
* Use of CrashHandler to provide automatic uploads of the most recent
crash log if an unclean shutdown was detected and it has not been
uploaded yet.
* Detection and handling of unclean shutdowns is delegated entirely to
the CrashHandler class
* Use of OBSLogReply has been replaced with the LogUploadDialog, which
asks for confirmation before new uploads of log files (confirmation is
skipped for files with available upload URLs already - only available
for crash logs with this change)
Architectural changes:
* OBSApp is the layer responsible for application launch and shutdown
states, as well as crash logs and application logs
* The actual handling is delegated to purpose-made classes which OBSApp
owns instances of
* OBSBasic in turn refers to OBSApp for all this functionality, and can
subscribe/connect to appropriate events exposed by OBSApp to this
purpose
* Implementation details (like the existence of the CrashHandler class)
are not exposed to OBSBasic or the LogUploadDialog
The amount of changes for normal log file upload have been purposefully
limited. A proper refactoring of the application log file handling will
move this code out of OBSBasic as well.
With the removal of all legacy code paths, obsconfig.h always exists and
the compile definition always gets set. As such, it's no longer
necessary to check for it.
As removing the definition itself could be seen as a breaking change,
this simply moves the definition to pc.in and cmake.in files for now to
preserve the value for plugins that might expect this to be set. We may
remove the definition entirely in a later release.
When a unique path is set up as the location for user settings,
profiles, or scene collections, migrating the files from one computer
to another will lead to confusing error messages as the original paths
might not exist on the new machine.
The default directories for configuration files are already created by
this point, so using those paths as a fallback should enable OBS Studio
to also create the corresponding fallback settings files.
