idtree: fix right shift of signed ints, crash on large ids on AIX
Right-shifting signed integers in undefined; indeed it seems that on
AIX with their compiler, doing a 30-bit shift on (INT_MAX-200) gives
0, not 1 as we might expect.
The obvious fix is to make id and oid unsigned: l (level count) is also
logically unsigned.
(Note: Samba doesn't generally get to ids > 1 billion, but ctdb does)
