[pgpool-committers: 693] pgpool: Fix race condition when using pool_get_passwd. The file descrip

[Tatsuo Ishii]

Fix race condition when using pool_get_passwd. The file descriptor to
pool_passwd is opened in pgpool main and pgpool child inherits
it. When concurrent connections try to authenticate md5 method, they
call pool_get_passwd and seek the fd and cause random md5 auth failure
because underlying fd is shared. Fix is, let individual pgpool child
open the file by calling pool_reopen_passwd_file.
Problem reported and analyzed by Jason Slagle in pgpool-general:1141.
