[Plplot-devel] Substantial changes to pl_create_tempfile and pl_create_tempfifo

[Alan W. I. <ir...@be...>]

A windows user "DrO" has recently discovered issues with the
pl_create_tempfile function.  (See the discussion in support request
#39 "Otherwise working PLPlot examples dont work on Win7/64").

I have tried to address those issues (after I got the OK for my ideas
from Andrew who was the originator of this code ) with commit 62b5e52
which constitutes a fairly substantial rewrite of both
pl_create_tempfile and pl_create_tempfifo (that latter function is
required by the tk device). PLplot doesn't work at all unless
pl_create_tempfile works so I used pretty extensive testing with
valgrind for both the svg and tk devices to validate my commit (for
details of that testing see the commit message). However, this testing
has a major limitation in that it has only been done on my particular
Linux platform (Debian jessie) at this time.

@Arjen, Phil, Hazen, and Greg:
I would very much appreciate further testing of this commit on the
MSVC, Cygwin, and MinGW-w64/MSYS2 Windows platforms that are available
to you to make sure I haven't introduced any issues for those
platforms.

@Others here:
Further testing on Linux and Mac OS X would also be appropriate.
