[tor/maint-0.2.5] When decoding a base-{16, 32, 64} value, clear the target buffer first

commit 47760c7ba5f1c87c945f4a018e3b3da6d127a8b9 Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Dec 22 12:56:35 2014 -0500 When decoding a base-{16,32,64} value, clear the target buffer first This is a good idea in case the caller stupidly doesn't check the return value from baseX_decode(), and as a workaround for the current inconsistent API of base16_decode.
