... stacktrace into a file on non-Win32 systems. This has a few advantages: - First, we don't need to duplicate stacktrace code inside the independent gimp-debug-tool (I even noticed that the version in the tool was gdb-only and not updated for lldb fallback; proof that code duplication is evil!). Instead, even on a crash, we can create the stacktrace from the main binary and simply pass it as a file. - Secondly, that allows to fallback to the backtrace() API even for crashes (this was not possible if the backtrace was done from a completely different process). That's nice because this makes that we will always get backtraces in Linux (even though backtrace() API is not as nice as gdb/lldb, it's better than nothing). - Finally this makes the code smaller (i.e. easier to maintain), more consistent and similar on all platforms.
