fix linked list corruption in flockfile lists
commit 5345c9b884e7c4e73eb2c8bb83b8d0df20f95afb added a linked list to track the FILE streams currently locked (via flockfile) by a thread. due to a failure to fully link newly added members, removal from the list could leave behind references which could later result in writes to already-freed memory and possibly other memory corruption. implicit stdio locking was unaffected; the list is only used in conjunction with explicit flockfile locking. this bug was not present in any releases; it was introduced and fixed during the same release cycle. patch by Timo Teräs, who discovered and tracked down the bug.
