This hot path was discovered by retronym using FlameGraph.
This removes intermediate creation of Array.
`filesModifiedBytes` in particular was bad as it was going through all `*.class` files, each generating an Array. This replaces that with `fileModifiedHash` that accepts `MessageDigest`.
According to the flamegraph, evalCommon footprint reduced from 4.5% to 3.6%.
Using `time sbt reload reload reload exit`, the median reduced from 41.450s to 39.467s.
previously I was using separate thread in a forked test to test the server, but that is not enough isolation to run multiple server tests.
This adds `RunFromSourceMain.fork(workingDirectory: File)`, which allows us to run a fresh sbt on the given working directory. Next, I've refactored the stateful client-side buffer to a class `TestServer`.

This works around the name conflict between sbt.test package and sbt.Keys.test.
1. sbt.test package is renamed to sbt.scriptedtest. This allows 1.0 plugins and builds to use `test` to mean `Keys.test`.
2. To keep binary compatibility for sbt 0.13 scripted, I am adding `sbt.test.ScriptedRunner` and `sbt.test.ScriptedTests` in `scripted-plugin` artifact.
3. Another affected user is Giter8 plugin that uses ScriptedPlugin. Since the intereactions are limited to `sbt.ScriptedPlugin.*`, we should be fine here. - https://github.com/foundweekends/giter8/blob/v0.11.0-M2/plugin/src/main/scala-sbt-1.0/giter8/SBTCompat.scala
Fixes#3538
This brings in `sbt.ScriptedPlugin` as `sbt.plugins.ScriptedPlugin` into sbt mothership.
In addition, `sbt.plugins.SbtPlugin` is added that enables the scripted plugin and `sbtPlugin := true`.
This allows plugin authors to bring in scripted plugin by writing:
```scala
lazy val root = (project in file("."))
.enablePlugins(SbtPlugin)
```
