Add recursive flag for adapt to mesh handle #2244
Description
Feature request
In #2057, set_adapt for the mesh handle is defined. By writing a test, i noticed that the flag recursive does not work out straightforward. Flag is currently removed for the mesh handle.
Current status:
Error occurs (or more precisely infinite runtime) because in t8_forest_adapt in the case of set_adapt_recursive, a list with elements to be refined refine_list is created. The elements are not updated in the mesh handle and no list is created such that the mesh handle adapt works with the old elements. The get_level will not change such that an infinite loop is created if the adapt callback is called recursively.
The infinite loop occurs with the first element to be refined in the test case, coarsening wasn't a problem.
