[pgpool-committers: 10441] pgpool: Fall back to prompting for password if reading from .pcppass fi

[Bo Peng]

Fall back to prompting for password if reading from .pcppass file fails.

If reading password from .pcppass file fails, it should fall back to prompting the user for input,
similar to how PostgreSQL handles .pgpass.

This commit also changes the following messages to be displayed without requiring the -d option:

    WARNING: password file \"%s\" is not a plain file
    WARNING: password file \"%s\" has group or world access; permissions should be u=rw (0600) or less
