liburcu: update to 0.9.1

Remove all patches: one of them is fixing a problem with gcc 4.8
that is no longer in use, and the other two are backports.

LICENSE checksum has changed, but visually the text has stayed the same.

-Subject: [PATCH] uatomic: Specify complete types for atomic function calls
-
-This was unearthed by clang compiler where it complained about parameter
-mismatch, gcc doesnt notice this
-
-urcu/uatomic/generic.h:190:10: error: address argument to atomic builtin
-must be a pointer to integer or pointer ('void *' invalid)
-                return __sync_add_and_fetch_4(addr, val);
-
-Fixed all instances thusly
