cat dde2516304 dbus: handle bizarre dbus proxy behaviour
There is a strange behaviour in xdg-dbus-proxy where if any interface string when stripped of a single ".*" suffix does not contain a '.' byte anywhere, the program will exit with code 1 without any output. This checks for such conditions to make the failure less confusing.

cat e587112e63 test: check xdg-dbus-proxy termination
This process runs outside the application container's pid namespace, so it is a good idea to check whether its lifecycle becomes decoupled from the application.

cat 31b7ddd122 fst: improve config
The config struct more or less "grew" to what it is today. This change moves things around to make more sense and fixes nonsensical comments describing obsolete behaviour.

This should never be a problem, however in case it happens printing a warning message is better than relying on the runtime to panic.

cat e9a7cd526f app: improve shim process management
This ensures a signal gets delivered to the process instead of relying on parent death behaviour.

SIGCONT was chosen as it is the only signal an unprivileged process is allowed to send to processes with different credentials.

A custom signal handler is installed because the Go runtime does not expose signal information other than which signal was received, and shim must check pid to ensure reasonable behaviour.
