[pgpool-committers: 2116] pgpool: Change pgpool_status file format to ASCII.

[Tatsuo Ishii]

Change pgpool_status file format to ASCII.

Changing to ASCII will bring some benefits:
- Easy to check the file contents by using ordinary text tools
- Easy to modify the contents. This is useful if you set longer health check time out.
  For example, newly added backend will cause failover and it might take long time
  until the procedure finishes. By editing pgpool_status to set the new node
  status as down, you could avoid health checking for the node.

Note that the new file reader understands old binary format
pgpool_status for easy migration from older versions of pgpool-II.
