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

This is actually tied up in [here|https://reviews.apache.org/r/66431/], but it needs to be split out.

> The function {{os::ftruncate}} on Windows uses the CRT API {{_chsize_s}} which requires an integer file descriptor. We can replace this with the semantically similar if not equivalent logic of {{SetFilePointer}} followed by {{SetEndOfFile}}. Major different is that it doesn't write null bytes when extending the file; it leaves the data uninitialized.
