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.
