This removes OkHttp dependency.
This also removes an experimental feature to customize HTTP for Ivy called
CustomHttp we added in sbt 1.3.0.
Since LM got switched to Coursier in 1.3.0, I don't think we advertized
CustomHttp.
The `XDG_RUNTIME_DIR` environment variable will be used to choose the base directory in which the sockets will be created by **sbt**. This can help when issues such as #6777 appear. There are other related issues, such as #6101, [Metals issue #2235](https://github.com/scalameta/metals/issues/2235), [Che issue #18394](https://github.com/eclipse/che/issues/18394). Those are closed issues, but there are some cases in which the solution does not work (such as the case in #6777). Furthermore, the solution given seems more like a workaround than an actual fix.
**What causes this issue?**
At least in my case, the **ServerAlreadyBootingException** is thrown after **sbt** tries to create a Unix domain socket and fails. In my specific environment, I was not able to create the sockets in some directories because they were mounted on an NFS. This prevented me from using any automated sbt command on any of those directories (Metals uses sbt under the hood, and it was not able to start because of the ServerAlreadyBootingException), which in turn resulted in me not being able to use Metals on a project that was created on any of those directories.
**How is the issue solved in this PR?**
If the `XDG_RUNTIME_DIR` environment variable is set, then sockets will be created in a folder with a hashed name, inside the directory `XDG_RUNTIME_DIR/.sbt/`. If this variable is not set, everything works exactly the same as always.
Let's see an example:
1. My environment variable `XDG_RUNTIME_DIR` is set to /home/alonso/.runtime-dir`
2. I create my project in `/home/alonso/workspace/hello-world`
3. I run `sbt compile`
4. The socket is created in `/home/alonso/.runtime-dir/.sbt/sbt-socket102030405060/sbt-load.sock`. The number **102030405060** is a hash that is computed from the base directory of the project (it is actually the same hash that is produced in order to create sockets in Windows) and it will be different depending on the location of the project
5. The sbt command executed correctly, which would not have happened if the socket had been created in the `home/alonso/workspace` directory or any of its subdirectories (in this example, `/home/BlackDiamond/workspace` corresponds to a network file share)

At some point the watchOnTermination callback stopped working. I'm not
exactly sure how or why that happened but it is fairly straightforward
to restore. The one tricky thing was that the callback has the signature
(Watch.Action, _, _, _) => State, which requires propagating the action
to the failWatch command. The easiest way to do this was to add a
mutable field to the ContinuousState. This is rather ugly and reflects
some poor design choices but a more comprehensive refactor is out of
the scope of this fix.
This commit adds a scripted test that ensures that the callback is
invoked both in the successful and unsuccessful watch cases. In each
case the callback deletes a file and we ensure that the file is indeed
absent after the watch exits.
This PR makes changes to the existing `xsbti.Problem` to account for an
optional diagnostic code that the compiler can return for a given
diagnostic and also related information.
Given a piece of code like:
```scala
try {}
```
You'll receive the following:
```
-- [E002] Syntax Warning: /Users/ckipp/Documents/scala-workspace/dotty-error-index/examples/002_EmptyCatchAndFinallyBlockID.scala:3:2
3 | try {}
| ^^^^^^
| A try without catch or finally is equivalent to putting
| its body in a block; no exceptions are handled.
```
The `E002` here is the actual code. Right now there would be no
description.
Some diagnostics have multiple positions that they need to represent.
You can see an example of this
[here](lampepfl/dotty#14002) in Dotty with the
use of inlining. Instead of needing to rely on including all of that
information in the diagnostic message it can now be extracted out into
a `DiagnosticRelatedInformation`.
These changes reference the conversation in #6868
