Memory leaks and uninitialized values in Trust Router / TID code

A substantial number of errors are found by running valgrind on the trust_router or tids binaries. Many of the leaks are likely harmless because they occur only in TID handling sub-processes, which are short-lived. It would still be nice to clean these up or verify that they are, in fact, tolerable.

Running valgrind to see these: as root, "libtool --mode=execute valgrind --leak-check=full --track-origins=yes <binary> [options...]"
