b1eea6d4fe [seccomp] Whitelist rseq syscall
Used by glibc 2.35 and later.

f126b88781 [seccomp] Whitelist newfstatat and fix a few #ifdefs
Some newer versions of either glibc or libsqlite3 seem to require this
syscall for the server to terminate properly.

2dbe2629c1 Tweak CNShared
* Separate pruning frequency from timeout
* Pluralize CNShared map: login -> logins
* Increase connection timeout to 15 minutes
* Do not deallocate a nullptr in playerEnter()
* Kill connections rejected by playerEnter()
* Remove redundant inclusions of mutex headers in a few places

741bfb675b Revamp CNShared logic
* Use a specialized connection object
* Copy the Player object less frequently
* Use a randomly generated serial key for shard auth
* Refuse invalid shard connection attempts
* Clean up connection metadata when a Player joins the shard
* Prune abandoned connections when they time out

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

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.

d3af99fcef A few cosmetic changes in Missions.cpp
* Removed a redundant failure case in endTask()

* Removed unnecessary comment in mobKilled()

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.

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.

25ce0f6d82 Rewrite /lair command
This wasn't strictly necessary as this command has outlived its
usefulness, but I had gone ahead and rewritten it because it was (barring
taskStart()) the only place in the codebase that accesses Chunking::chunks
outside of Chunking.cpp. This became apparent during a (currently paused)
effort to improve the API that the Chunking namespace exposes to the
rest of the codebase.

I went ahead and rewrote the rest of this command as it was poorly
implemented anyway. This has been sitting in my working directory
uncommitted for a few months, so I may as well push it.

Mobs can now get criticial hits
Explanation: it was uncertain whether mobs could perform critical hits, since the color of damage numbers didn't change at all. However, I found that male characters will actually use a different sound effect when receiving a crit (I confirmed this SFX appeared in old FF videos), so I went ahead and re-enabled it.

5c1bb0acc9 Add enabledpatches config option
The server administrator must now specify which patches they want the
server to load (if deviating from the defaults). There are multiple
reasons for this:

* It's useful to be able to pick and choose which patches you want to
boot the server with; without having to move the directories in and out
of the patch directory
* This way, we can have different default patches for different builds
of the game (104 vs 1013)
* ...ergo, it's easier to rapidly switch builds without having to
rearrange your workspace to properly run them
* This also allows us to remove the std::filesystem stuff, which has
spotty compatibility with slightly older (but still current) versions of
the compilers
