espeak: do not call espeak functions after a failed reinitialization

Browse source 
When resuming from CMD_PAUSE, queue_process_entry ignored the result
of reinitialize_espeak: if espeak_Initialize failed, paused_espeak
remained set, yet the entry was processed anyway, calling
espeak_Synth & co on a terminated engine.  Combined with the
busy-retry loop, this produced an endless stream of failing calls
against a dead engine.

Make reinitialize_espeak report failure, and when espeak is
unavailable, leave the entry queued and back off before trying to
reinitialize again.
