Log: [libthr] revert change of visibility of _thread_keytable to unbreak debugger Fix regression by r318539. The sysutils/pstack uses library libthread_db to read information about threads state. The function pt_ta_new makes lookup of several key symbols including _thread_keytable. But r318539 mades this field static. It causes silent ignore of libthr library by pstack and as result sysutils/pstack doesn't output any thread information. This fix changes this field back to non-static.
