Better error messages than "something went wrong in type 20".
Also fix bazel-asan/tsan builds.

refactor: Add mem module to allow tests to override allocators.
...
This will allow us to do more interesting things with memory allocation
within toxcore, and allow fuzzers to explore various allocation failure
paths.

eventually.
Also update the bootstrapd checksum, since the alpine image changed a
bit.

test: Enable fuzzing for TCP.
...
If the `recvbuf` network function returns 0 all the time, that means
there is never any data available on the TCP socket. This change makes
it so there is a random amount of data available on the TCP socket.
This invalidates the bootstrap fuzzer corpus.

fix: Fix potential array out-of-bounds in DHT random node retrieval.
...
It can't happen in almost every reality, except when the RNG is fairly
broken and doesn't add 2 fake DHT friends on startup. Still, this code
should be defensive and never index outside `num_friends` elements.

test: Don't abort fuzz test when tox_new fails.
...
Right now, it can't fail, but later we want the fuzzer to randomly let
I/O functions fail, so we shouldn't assert tox_new succeeded.

Ideally this would be able to reach some of the events, so we can write

These help creating fuzzer fixtures with non-trivially constructed
