  1. Issue 17912: Add function for creating a temporary file. 

    This adds std.file.createTempFile, which creates a temporary file with a
random name (optionally with a specified prefix and/or suffix). By
default, the file is empty, but if data is passed to createTempFile,
then the file is populated with that data just like it would have been
with std.file.write. The name of the file that was created is returned.
So, essentially, createTempFile is like write except that it generates
the file name for you and returns it.

Previously, we added scratchFile to std.stdio, which was like
createTempFile except that it gave you an open File object, but it was
scrapped, because the dependencies that it added to std.stdio made
"hello world" bigger. See:
https://issues.dlang.org/show_bug.cgi?id=14599

Just like scratchFile did, createTempFile ensures that a filename is
selected which did not exist previously so that the file can't be
hijacked with different permissions by someone creating a file with the
same name beforehand (the randomness of the name should make that
effectively impossible, but the way that createTempFile opens the file
guarantees it).

These changes also consolidate some of write's implementation across
OSes, since the writing portion of writeImpl was esentially identical
across OSes but needlessly duplicated. That consolidated functionality
is then also used by createTempFile.
