Removed a pointless declaration of a function in lan_discovery_test
and cleaned up the one error message there. Did an entire restructuring
of the version_test using macros that resulted in fewer lines of code but more
thorough testing.
Formatting of version_test.c
back to old way, save comments and one change
Missing space
My greatest enemy
Add `#include <cstdio>` for `std::printf`.
Make tox.c unambiguously parseable.
Rules:
1. Constants are uppercase names: THE_CONSTANT.
2. SUE[1] types start with an uppercase letter and have at least one
lowercase letter in it: The_Type, THE_Type.
3. Function types end in "_cb": tox_friend_connection_cb.
4. Variable and function names are all lowercase: the_function.
This makes it easier for humans reading the code to determine what an
identifier means. I'm not convinced by the enum type name change, but I
don't know a better rule. Currently, a lot of enum types are spelled like
constants, which is confusing.

Use run_auto_test.h test fixture for some auto-tests.
Most of the auto-tests should use this fixture, but I've only done a few
to set an example.
