ENH/FIX Change Tree underlying data structure
...
* avoid segfault (#2726 ) by setting base on numpy arrays
* A struct array for tree nodes and values array (size indeterminate at
compile time) are the only underlying structure, so each node is locally
grouped memory, and joblib dumps will save only two numpy files per
tree.
* predict() uses the value array's take method, reducing code repetition

Replaced all BSD style licenses with "BSD 3 clause"
Not checked yet!
Removed duplicate "3 clause, 3 clause"
Removed trailing period if exists
Fixed some missed licences, still about 50 to do, but those can be automated
Think I got the last of them.
Apparently me and sed have different ideas of regex.
Found a few more
