129d1c2fe3 Use a specialized null value for ChunkPos
This prevents logic errors related to being in chunk 0 0 0.

Also:

* Moved some duplicated chunk teleportation logic to a new helper
  function
* Made ChunkPos into a proper class so it can default to INVALID_CHUNK
  when default-initialized
* Reversed the inclusion order of Chunking.hpp and Entities.hpp to work
  around problems with type definitions

1bd4d2fbee Cleanly remove player when an exit is requested
The client will actually do this itself when clicking the quit button in the tilde menu, but for the idle timer the connection would remain open until the game is closed.

57c9f139a2 Fix quest item drop chances being shared between missions
In our original implementation, quest item drops were rolled on the
spot, so the chances of getting two quest items for different missions
in a single kill (where both missions have you kill the same mob) were
independent of each other.

When we made quest item drop chances shared between group members so
players doing missions together would progress at the same rate, we
accidentally linked the quest item odds of different missions together.

This change makes it so that the odds are per-task, so they're shared
between different group members doing the same tasks, but distinct for
different tasks being done by the same player.

28bfd14362 Quick-fix for doDamage() crash
Couldn't get a reliable repro, but this is probably what that bug was.
It's not very throughly investigated, but we'll be tweaking those parts
of the codebase anyway, so we can examine if there's a deeper issue
later.

384a2ece78 [sandbox] Seccomp filter tweaks
* Restrict fcntl() to only the flags we need
* Non-fatally deny tgkill() and rt_sigaction() so that segfaults don't
  result in a SIGSYS. They're debuggable either way, but this way it's
  clearer what the issue is right away.
* Allow truncate() and ftruncate() for sqlite's alternate journal modes
* Slight macro cleanup
* Add missing colon in a DB log message

We don't need to worry about compilation problems arising if glibc or
musl-libc add their own wrapper for the seccomp() syscall in the future.
Ours will/would just silently take precedence over the external one
without interfering with compilation. This should work regardless of
whether libc uses weak symbols and regardless of whether libc is
dynamically or statically linked into the executable. The wrapper's
signature has been stripped of its static and inline qualifiers, as it
must match the exact declaration the libc headers will/would use.

Further, if a pre-compiled binary is run on a system which genuinely
doesn't support seccomp(), it'll just return ENOSYS and the server will
terminate with an error. The user can then just disable the sandbox in
the config file. We don't need any special logic for that scenario.

There are some network configurations in which it's undesirable; such as

2eb64540d1 Usernames are now case-insensitive
This fixes a UX issue, where if you accidentally capitalized a letter
in the username when logging in, it would instead create a new account.

The behavior was confusing, since to the user it looks as if their
characters were deleted or progress was not saved.

In order for this to work, duplicate accounts (e.g. username and USERNAME)
need to be deleted/renamed. The server will *detect* if any duplicates
exist. If any are found, it will direct the server operator to a pruning
script, or they can choose to resolve the duplicates manually.
