[pgpool-committers: 6489] pgpool: Feature: Check if socket file exists at startup and remove them

[Bo Peng]

Feature: Check if socket file exists at startup and remove them if PID file doesn't exist.

If the previuos socket files exist, pgpool startup fails due to bind() failire.
This commit is to remove socket files at startup if PID file doesn't exist.

Also, I found some messages are effectively ignorede because log system is not yet initialized at start point.
I changed them to standard fprintf(stderr...).
