* The default chunk size for reading from file-likes in ``iterparse()`` was increased

from 32 KiB to 64 KiB and is now configurable with a new ``chunk_size`` argument.

* Writing to Python file objects minimises data copying by passing buffers around.

Other changes

-------------

* Some internal adaptations were made for libxml2 2.14.x and 2.15.x.

* The ``xmlDict...`` C functions of libxml2 are now declared in ``tree.pxd``.

They remain in ``xmlparser.pxd`` for legacy reasons but Cython code that uses them

should migrate the import to ``tree.pxd``.
