[pgpool-committers: 5092] pgpool: Do not update pgpool_passwd if the password length is incorrect

[Tatsuo Ishii]

Do not update pgpool_passwd if the password length is incorrect.

For Pgpool-II 3.7 or before, the password stored in pool_passwd is MD5
password only.  So check the correctness of pool_passwd by scanning
entire file.

Patch created by Takuma Hoshiai. Minor error message tweak by me.
See bug425 for more details.
