f031513470 [ntcore] NetworkTable::GetSubTables(): Remove duplicates (#5076) 
In Java, a set is used. Use a two-stage approach in C++ to achieve the
same result.

5d3a133f9f Remove spaces in NOLINT comments (#5407) 
clang-tidy ignores the category filter if there's a space. wpiformat now
ignores categories it doesn't understand, so we can remove the spaces.

652d1c44e3 [wpiutil] Upgrade to macOS 12 to remove concept shims (#5379) 
The macOS deployment target has been upgraded from 10.15 to 11. Also, a
deprecation warning for sprintf() in libuv was suppressed.

Continue to use WPI_DEPRECATED macro for constructors until clang-format is fixed.

2108a61362 [ntcore] NT4 client: close timed-out connections (#5175) 
Pings are sent every 3 seconds.  If we don't see a response to the last
ping before it's time to send the next one, close the connection.

0a66479693 [ntcore] Optimize scan of outgoing messages (#5227) 
The algorithm being used for scanning outgoing messages was O(n^2)
because it did a full linear search and then appended. This scan is
performed for each client. If there is a burst of outgoing changes, the
outgoing queue can get quite deep all at once and this scan can be very
slow. Replacing with a map fixes this.

53b5fd2ace [ntcore] Use int64 for datalog type string (#5186) 
There's a spec difference between NT4 and datalog for integers; NT4 uses
"int", datalog uses "int64". We were using "int" for datalog as well.

Also add backwards compatibility support to datalogtool for treating
"int" as "int64".

8068369542 [wpinet] uv: Stop creating handles when closing loop (#5102) 
This prevents EventLoopRunner::Stop() from hanging in the case when
new handles are created after the async walk closes all the handles.

805c837a42 [ntcore] Fix use-after-free in server (#5101) 
The client name deduplication didn't properly deduplicate.  Instead,
always append the client index to guarantee a unique name.

843574a810 [ntcore] Use wpi::Now instead of loop time for transmit time 
As the send function is called after local processing, there can be a
substantial delay between the loop time and the actual send.

19267bef0c [ntcore] Output warning on property set on unpublished topic (#5059)

49459d3e45 [ntcore] Change wire timeout to fixed 1 second (#5048) 
Previously the timeout was 10 times the update rate, so with low update
rates it could be as small as 50 ms, causing spurious disconnects when
large or many topics were published.

b61ac6db33 [ntcore] Add client disconnect function (#5022) 
As setServer doesn't disconnect, it's useful to have a function that
disconnects without needing to completely stop the client.

8785bba080 [ntcore] Special-case default timestamps (#5003) 
Previously, a setDefault() on the server could override a client doing a
real set() if the time offset between client and server was negative,
resulting in a negative timestamp from the client.  This is a not
uncommon situation with robot code, as the robot code always starts at
time 0, so any clients that set values earlier (in real time) would have
negative timestamps.

Also improve special casing of 0 in the transmit side to make sure a
normal timestamp will never get sent as 0.

9e5b7b8040 [ntcore] Handle topicsonly followed by value subscribe (#4991) 
Previously this wouldn't send the last value on the value subscribe if a
topics only subscription already existed.

008232b43c [ntcore] Write empty persistent file if none found (#4996) 
This avoids the warning appearing on every startup when persistent
values aren't used.

Also add note to message saying it can be ignored if persistent values
aren't expected.

getKeys() work properly regardless of other subscriptions.
