fb2c170b6e [ntcore] Simplify local startup (#4803)
The current approach was slightly more efficient but didn't correctly
handle meta-topic publishing for topics published before the server was
started.

a865f48e96 [ntcore] Pass pub/sub options as a unified PubSubOptions struct (#4794)
In Java, PubSubOption is still used for passing options, but this
simplifies C++ use substantially, as it allows aggregate construction.

342c375a71 [ntcore] Add subscriber option to exclude single publisher
This enables limited self-exclusion for entries seeing their own changes
or similarly with a pub/sub pair.

aa6499e920 [ntcore] Fix special topic multi-subscriber handling (#4740)
It now matches server behavior, where "" doesn't match special topics.

Also fixes duplicate notification that could occur in some cases.

Essentially this separates duplicate value detection between network and
local.

ffbfc61532 [ntcore] Add NetworkTable table-specific listeners (#4640)
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.

4ba16db645 [ntcore] Various fixes and cleanups (#4544)
* 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

1c3c86e9f1 [ntcore] Cache GetEntry(name) values (#4531)
These are typically cached at higher levels anyway, but cache at lowest
C++ layer as well for consistency with NT3.

794669b346 [ntcore] Revamp listeners (#4511)
- 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

ae208d2b17 [wpiutil] StringExtras: Add substr() (#3742)
Unlike std::string and std::string_view, this substr() allows a start
greater than the length of the string, in which case an empty string
is returned.  This matches llvm::StringRef behavior.

d6f185d8e5 Rename tests for consistency (#3592)
I started with the output of styleguide#217, then renamed a few classes
to fix compilation.

ntcore's StorageTest needed some manual renaming since it put the Test
word in the middle instead of at the end.

One limitation of wpiformat is test cases that were only named "Test"
were unmodified, and an error was generated. These test cases were
manually given more descriptive names:

* TimedRobotTest mode test cases had "Mode" appended to the name. Java
  tests were renamed to match.
* UvAsyncTest and UvAsyncFunctionTest cases were given alternate names

161e211734 [ntcore] Match standard handle layout, only allow 16 instances (#3577)
Now that there are only 16 instances, store them all statically.

Make tests more reliable by using different ports for each connection in listener tests.

- 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).

fmt::print() with wpi::raw_ostream

5fe8f9017f [build] Refactor CMake flags (#2788)
The CMake enable/disable flags as currently structured are a confusing mix of
WITH, WITHOUT, and USE with odd defaults.  This changes the flags to consistently
use WITH and default the build options to everything enabled.

f84018af5f Move entirety of llvm namespace to wpi namespace.
During shared library loading, a different libLLVM can be pulled in, causing
llvm symbols from dependent libraries to resolve to that library instead of
this one. This has been seen in the wild with the Mesa OpenGL implementation
in JavaFX applications (see wpilibsuite/shuffleboard#361).

This is clearly a very breaking change. For some level of backwards
compatibility, a namespace alias from llvm to wpi is performed in the "llvm"
headers.  Unfortunately, forward declarations of llvm classes will still break,
but compilers seem to generate clear error messages in those cases
("namespace alias 'llvm' not allowed here, assuming 'wpi'").

This change also moves all the wpiutil headers to a single "wpi" subdirectory
from the previously split "llvm", "support", "tcpsockets", and "udpsockets".
Shim headers will be added for backwards compatibility in a later commit.
