Replace lib:/// scheme by mvn:/// and file:/// and jar+file:/// everywhere

[jurgenvinju]

This PR:

• removes the implementation and use of the lib:/// scheme. This also removes a lot of printing on stderr.
• builts on the introduction of the mvn:/// scheme
• moves the original resolution code from the lib:/// scheme implementation to PathConfig.createProjectConfig...
• adds path resolution error messages and warnings to a PathConfig field called messages, including version clashes on the rascal and rascal-lsp project, missing pom.xml files, etc.
• changes all clients of PathConfig.createProjectConfig to pretty print resolved paths and error messages.

These were the TODO's:

• shorten all paths into the local maven repo to mvn:///groupid!artifactid!version
• replace lib:/// in the processing of dependencies (Require-Libraries) with other schemes, including mvn, file, and jar+file. This means sometimes dynamically computing an absolute path rather than leaving it to an opaque scheme.
• remove Require-Libraries implementation (is replaced by mvn dependency:list and bundle dependencies in Eclipse)
• remove lib resolver from the implementation
• test, test, test
• figure out how the rascal summaries for the IDE can work without the lib:/// scheme that is now introduced by the Packager. Some form of relocation is necessary, but it can't be the old lib:/// scheme anymore.

This fixes #1916, #1961, #1826, #1825, #1824, #1777, #1767, and #1478

Downstream projects like rascal-lsp and rascal-maven-plugin may need some modifications:

• In particular everywhere we use URIUtil.correctLocation("lib", name) should become PathConfig.resolveDependencyFromResourcesOnCurrentClasspath("name") or URIUtil.correctLocation("mvn", etc.)
• Where we receive a new PathConfig instance we can chose to register or print the diagnostic messages.

This PR fixes #1961

[DavyLandman]

I've taken a first look at the code, not sure why everything is happening yet, but it seems like this will cause a whole downstream of changes and issues, so we're going to have to write down some new documentation of how it is supposed to be used I think.
