Testing rust 1.57.0

[Havard Eidnes <he%NetBSD.org@localhost>]

Hi,

you may have noticed that pkgsrc-wip has version 1.57.0
committed.  I'm on the verge of committing that version to
pkgsrc-current.

Based on the description and table in

  https://www.pkgsrc.org/rust/
  
I've drawn up the following table as a normal text file, and
crossed off completed tests and ongoing actions.

However, I also now have a pkgsrc-wip update to 1.58.0 lined up,
and would therefore like to get 1.57.0 into pkgsrc proper as an
interim step.  So...  I'm asking how much more testing we'll need
before I can commit the 1.57.0 update, and I'm also soliciting
filling in some of the blanks in the table below.  Doing all the
steps below is a Lot of work, and so far I've not seen anything
pointing in the direction of an issue with rust itself.

Regards,

- Havard

x - successfully completed
o - ongoing (some of these take a while)
w - waiting for dependent step, intention to complete
u - failure unrelated to rust itself (other package)
f - failed
