Subject: [PATCH 1/3] main: if deactivate when already deactivated return
 immediately

We were trying to ignore second deactivate requests, but
were instead crashing because we're trying to use a nullified
trigger.

This commit makes sure things don't go crashy when a user
does "plymouth deactivate" on an already deactivated plymouthd.

Subject: [PATCH 2/3] two-step: don't update progress when idle

We've already reach a state where we aren't drawing anymore, etc,
so don't update progress and potentially fire off animations
that won't be seen.

Subject: [PATCH 3/3] main: make plymouth show-splash idempotent

plymouth show-splash causes hairy things, that should only happen once,
like activating renderers to happen.

This commit makes subsequent show-splash calls be no-ops.
