Changes

ctf: Support overlapping enum values

Support overlapping of both single values and values ranges in the enum
declaration. The internal structure is changed from a TreeSet to a
Multimap. Overlapping can occur for the same key in the multimap
(overlapping single values) or for different keys in the multimap
(overlapping value ranges).

The query result label is the same when no overlap occurs, but when
there is overlap, the matching labels are returned as [l1, l2, ...].
This format can also be returned in the lookup table.

Add unit tests for overlapping and adding without specifying range.

callstack.core: Add kernel thread statuses to tests

[Added] KernelAnalysisStub to add kernel thread statuses to tests
[Added] getStatusIntervalsForThreads to KernelThreadInformationProvider

To add these tests, a stub of the kernel analysis has been added and the
FlameChartDP has been modified to depend on the HostModel and not query
directly from the ThreadStatusDP.

To make the changes to the FlameChartDP, the CompositeHostModel has been
modified to query the thread statuses from multiple threads in one
query.
