/**
* Validate a given classpath and output location for a project, using the following rules:
*
* <ul>
* <li>Classpath entries cannot collide with each other; that is, all entry paths must be
* unique.
* <li>The project output location path cannot be null, must be absolute and located inside the
* project.
* <li>Specific output locations (specified on source entries) can be null, if not they must be
* located inside the project,
* <li>A project entry cannot refer to itself directly (that is, a project cannot prerequisite
* itself).
* <li>Classpath entries or output locations cannot coincide or be nested in each other, except
* for the following scenarios listed below:
* <ul>
* <li>A source folder can coincide with its own output location, in which case this
* output can then contain library archives. However, a specific output location
* cannot coincide with any library or a distinct source folder than the one referring
* to it.<br>
* Note: Since 3.8, this behavior can be overridden by configuring {@link
* JavaCore#CORE_OUTPUT_LOCATION_OVERLAPPING_ANOTHER_SOURCE}
* <li>A source/library folder can be nested in any source folder as long as the nested
* folder is excluded from the enclosing one.
* <li>An output location can be nested in a source folder, if the source folder coincides
* with the project itself, or if the output location is excluded from the source
* folder.
* </ul>
* </ul>
*
* Note that the classpath entries are not validated automatically. Only bound variables or
* containers are considered in the checking process (this allows to perform a consistency check
* on a classpath which has references to yet non existing projects, folders, ...).
*
* <p>This validation is intended to anticipate classpath issues prior to assigning it to a
* project. In particular, it will automatically be performed during the classpath setting
* operation (if validation fails, the classpath setting will not complete).
*
* <p>
*
* @param javaProject the given java project
* @param rawClasspath the given classpath
* @param projectOutputLocation the given output location
* @return a status object with code <code>IStatus.OK</code> if the given classpath and output
* location are compatible, otherwise a status object indicating what is wrong with the
* classpath or output location
