Fix #2186: Synchronize classpath handling with Scala 2.12
This commit is a very crude port of the classpath handling as it exists
in the 2.12.x branch of scalac (hash: 232d95a198c94da0c6c8393624e83e9b9ac84e81),
this replaces the existing Classpath code that was adapted from scalac
years ago.
This code was written by Grzegorz Kossakowski, MichaĆ Pociecha, Lukas
Rytz, Jason Zaugg and other scalac contributors, many thanks to them!
For more information on this implementation, see the description of the
PR that originally added it to scalac: https://github.com/scala/scala/pull/4060
Changes made to the copied code to get it to compile with dotty:
- Rename scala.tools.nsc.util.ClassPath to dotty.tools.io.ClassPath
- Rename scala.tools.nsc.classpath.* to dotty.tools.dotc.classpath.*
- Replace "private[nsc]" by "private[dotty]"
- Changed `isClass` methods in FileUtils to skip Scala 2.11
implementation classes (needed until we stop being retro-compatible with
Scala 2.11)
I also copied PlainFile.scala from scalac to get access to
`PlainNioFile`.
