Comparison operators which compared against every class member variable
now use C++20's default comparison operators.
Also remove operator!= that in C++20 is now auto-generated from operator==.
These are similar, but not quite identical to, the NT3 NetworkTable
table listeners.
Also add table topic-only multi-subscriber to ensure functions like
getKeys() work properly regardless of other subscriptions.
* NetworkTableInstance: set handle to 0 after destroy
* Fix multiple notifications of local values
* Detect mismatch between handles
* Server: fix setting min period when no topics
* Limit maximum number of subscribers/publishers/listeners
This helps find resource leaks and prevents them from causing excessive
slowdowns/crashes. The limit on each is currently set to 512.
* Don't use std::swap in move operation
- In both C++ and Java, add listener functions to Instance class (same as NT3 provided)
- Add WaitForListenerQueue functions (same as NT3 provided)
- Move Java non-poller implementation to Instance (previously only handled single instance)
- Change C++ listeners to take non-const references for subscribers etc to help avoid footguns from use of temporary objects (also add doc comment)
- Fix Preferences making .type persistent
This avoids the need for explicit value() calls (as compared to using
DoubleTopic). The unit name is published as the "unit" property.
Implementation note: the test needs to be in wpilibc because ntcore does
not depend on wpimath.
* TopicListener: Fix Add() return values
* Update PubSubOption poll storage documentation
* Update NetworkTableEntry::GetValue() doc
* Add documentation regarding asynchronous callbacks
* Unpublish entry: set publisher to nullptr
* Implement ValueListenerPoller default constructor
* Remove SetNetworkIdentity, make parameter to StartClient
* URI-escape client ID, improve error message
* Add connected message with client id; also improve disconnected message a bit
* Handle SetServers either before or after StartClient
* Fix client use-after-free; also delay reconnect after disconnect to rate limit
* Don't re-announce to already subscribed client; we especially don't want to send the last value again
* Always accept in-order sets, only use timestamp for tiebreak
* Fix LocalStorage::StartNetwork race
* Remove unused/unimplemented function
Also:
* [glass] Remove debug print
* [glass] Fix mpack string decoding
* [cameraserver] Fix up startclient
* Use explicit this capture required by C++20
* Use C++20 span
* Replace wpi::numbers with std::numbers
* Fix C++20 clang-tidy warning false positive in fmt
* Remove ciso646 include since C++20 removed that header
* Fix global-buffer-overflow asan warnings in ntcore tests
* Add DIOSetProxy constructor to HAL
* Upgrade MSVC compiler to 2022
* Bump native-utils to 2023.2.7 (changes to std=c++20)

* Fix C++ Publisher and Subscriber move assignment
* Fix Publisher comment typo.
* Publish: check that properties is an object.
Print a warning, but still publish, just with empty properties.
Add error print for unassigned type publish.
* Return boolean from SetProperties
* Document exception-throw in Java for invalid JSON.
I generated lists of includes and uses via
`rg -l deprecated.h | sort -u` and `rg -l WPI_DEPRECATED | sort -u`
respectively. If a file was in the first list but not the second, the
include was unused. If a file was in the second list but not the first,
the include needed to be added.
The non-NT portion has been moved to wpiutil.
The NT portion has been moved to ntcore (as NTSendable).
SendableBuilder similarly split and moved.
SendableRegistry moved to wpiutil.
In C++, SendableHelper also moved to wpiutil.
This enables use of Sendable from wpimath and also enables
moving several classes from wpilib to wpimath.
- Twine, StringRef, Format, and NativeFormatting have been removed
- Logging now uses fmtlib style formatting
- Nearly all uses of wpi::outs/errs have been replaced with fmt::print() or
std::puts()/std::fputs() (for unformatted strings).
- A wpi/fmt/raw_ostream.h header has been added to enable
fmt::print() with wpi::raw_ostream
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
This can be dangerous as it refers to a temporary, and GCC 9.0 warns about
its use. Instead add std::initializer_list overloads to common places it
was used in an initializer_list sense.
* Update MSVC arguments
* Fix json allocator
* Fix simulation diamond
* Bump gtest
* Remove empty varargs in unit tests
* Replace test case with test suite
* Remove deprecation warning in optional
* Remove need for NOMIXMAX to be defined in wpilib headers
