ARROW-360: C++: Add method to shrink PoolBuffer using realloc Added no explicit unit test for this as I want to keep the freedom to the allocator in the future to advise the PoolBuffer on an acceptable minimal size. In some cases it might be worth it to occupy a whole page. Resizing to a smaller size is tested though, so we already have a unit test ensuring that this code runs smoothly. Author: Uwe L.
