[bug#57702] [PATCH 0/8] Update rust-clap-3 to 3.2.17

[John Kehayias]

Hi everyone,

Just dropping a note that many of these packages are required for the IceCat 
update that Mark has on the gnuzilla-updates branch. There, some version of the 
needed packages for newer rust (which is on staging already) and rust-cbindgen 
exist, which overlaps with the packages in this patch series. I also had 
contributed similar patches to another channel for building the latest of 
Firefox, which Mark used (along with other's work) for the IceCat update.

Anyway, just wanted to chime in so that this can be coordinated and avoid 
duplicated work. I only looked at this patch series quickly before, but I think 
many of the duplicate patches needed for cbindgen were similar across the 
different versions and should be straightforward to migrate to their proper 
package home outside of gnuzilla. Last I heard staging being merged to master 
was imminent, which will give us the newer rust compilers as well.

Let me know if there is something I can do to help.

John
