> RBF: Format safe-mode related logic and fix a race.
>
> Both {{RouterAdminServer#enterSafeMode()}} and
> {{RouterSafemodeService#periodicInvoke()#leave}} can change the router state
> at the same time.
> Safe-mode change logic should be condensed into one method. And some races
> may happen in the current implementation, such as:
> # {{RouterAdminServer#enterSafeMode()}} set router stat to
> {{RouterServiceState.SAFEMODE}}
> # {{RouterSafemodeService#periodicInvoke()#leave}} got true when checking
> {{safeMode && !isSafeModeSetManually}}
> # {{RouterAdminServer#enterSafeMode()}} set {{safeMode}} and
> {{isSafeModeSetManually}} to {{true}}
> # {{RouterAdminServer#enterSafeMode()}} get {{true}} when checking safe-mode
> # {{RouterSafemodeService#periodicInvoke()#leave}} call {{leave()}} to leave
> safe-mode.
> This RBF is not in safe-mode and {{safeMode}} is {{{}false{}}}, but
> {{isSafeModeSetManually}} is {{{}true{}}}.
