I noticed that my custom WatchService was never cleaned up by sbt and
realized that after every build we were making a new WatchService. At
the same time, we were reusing the WatchState from the previous run,
which was using the original WatchService. This was particularly
problematic because it prevented us from registering any paths with the
new watch service. This may have prevented some of the file updates
from being seen by the watch service. Moreover, because we lost the
reference to the original WatchService, there was no way to clean it up,
which was a resource leak.

* 1.1.x:
Update mimaPreviousArtifacts/sbt.version
Introduce SBT_GLOBAL_SERVER_DIR env var to override too long paths
Handle very long socket file paths on UNIX
Conflicts:

Fixes#3821
Initially I missed why #3821 was failing.
Looking at it again, the error message reads:
```
Caused by: java.lang.IllegalArgumentException: Interface (NGWin32NamedPipeLibrary) of library=kernel32 does not extend Library
at com.sun.jna.Native.loadLibrary(Native.java:566)
at sbt.internal.NGWin32NamedPipeLibrary.<clinit>(NGWin32NamedPipeLibrary.java:38)
... 7 more
```
Inside `Native.loadLibrary`, it requires the "library" interface to extend `com.sun.jna.Library`, which this adds.
Fixes#3823
When you launch a second instance of sbt on a build, prior to this change it was displaying `java.io.IOException: sbt server is already running` on every command. This make it a bit less aggressive, and just display a warning once.
```
[warn] Is another instance of sbt is running on this build?
[warn] Running multiple instances is unsupported
```
Ref https://github.com/sbt/io/pull/96
Under RFC 8089, both u1 and u3 are legal, but many of the other platforms expect traditional u3.
This will increase the compatibility/usability of sbt server, for example to integrate with Vim.
Currently the server will try to start even if there are existing sbt sessions. This causes the second session to take over the server for Unix domain socket.
This adds a check before the server comes up and make sure that the socket is not taken.

To configure the log level of the server, this introduces a new task key named `serverLog`. The idea is to set this using `Global / serverLog / logLevel`. It will also check the global log level, and if all else fails, fallback to Warn.
```
lazy val level: Level.Value = (s get serverLogLevel) orElse (s get logLevel) match {
case Some(x) => x
case None => Level.Warn
}
```
`NGUnixDomainSocket` throws `java.io.IOException` instead of `SocketException`, probably because `SocketException` does not expose the contructor with a `Throwable` parameter.
To allow clients to disconnect, we need to catch `IOException`.
In addition to TCP, this adds sbt server support for IPC (interprocess communication) using Unix domain socket and Windows named pipe.
The use of Unix domain socket has performance and security benefits.
This adds a new option `dev` to the `reboot` command, which deletes the only the current sbt artifacts from the boot directory. `reboot dev` reads actively from `build.properties` instead of using the current state since `reboot` can restart into another sbt version.
In general, `reboot dev` is intended for the local development of sbt.
Fixes#3590
This adds a sbt.watch.mode system property that if set to 'polling' will
use PollingWatchService instead of WatchServiceAdapter (nio).
On macOS this will default to 'polling' and on all others 'nio'.
This is a temporary workaround for users affected by #3527
