[pgpool-committers: 8056] pgpool: Fix pcp_proc_info, show pool_processes and show pool_pools comm

[Masaya Kawamoto]

Fix pcp_proc_info, show pool_processes and show pool_pools command.

I added new fields to the result of those commands in following commit:
https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commitdiff;h=45152975fdf8d57deaff07dc6c34117fa8eeb3db

The usage of client_idle_limit was mistaken. Child processes are
restarted by child_life_time not client_idle_limit, and client_idle_limit
is related to Client idle duration and disconnects the connection.

So, I changed the display of Start time and Client idle duration.
I modify wait_for_connections function to calculate the time remaining
until the child process is restarted by child_life_time; Instead of
using child_life_time as the timeout for select(2), select(2) with 1 sec
timeout is looped through child_life_time times to get the elapsed time.

Moreover when there were multiple backends, Client idle duration was
only displayed in backend0, so I fix this too.
