[pgpool-committers: 267] pgpool: Reset ps status to idle when SELECT result fetched from memory

[Tatsuo Ishii]

Reset ps status to idle when SELECT result fetched from memory cache.
For this purpose new function pool_ps_idle_display() is created
and used because similar process exists in several places.
Some of them were wrong (for example, show pool_version did
not show correct transaction status). This part may be backpatched
to V3_1_STABLE but I do not want to risk to incorporate this
kind of refactoring (it seems it's not worth the trouble).
