Rust 1.39

[Chuck Musser]

Ok, cool. I did a pkg upgrade on my 5.6 system and used 1.40 to
successfully compile a program  that uses the new async/.await feature,
so that's pretty nice. Thanks for the work on the Rust port.

I have pushed  now what we used to create the bootstrap for 1.40 (which is now in  DPorts/master and in the binary packages), and that's the recommended  one to use in DragonFly BSD installations, it should work in both  release and master.

This directory contains  shared libraries whose names have long suffixes. I'm not sure where  these live on a "production" system.

Also, one of the existing  patches, to a part of LLVM had to be modified so that the proper  name of a field in the statvfs structure was used. I'm not sure how  much of this stuff is correct or can be incorporated into a more  official build, but it's there for anyone who wants to look around.
