all: changeover to eliminate all direct use of master/slave terminology

[deadprogram]

This PR is to changeover to eliminate all direct use of master/slave terminology both for the Git repo, and also the TinyGo peripherals. See https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names

We will also need to change the master branch name to release, and change the default branch in Github.

@johanbrandhorst any way to change the branch used by the repo used for the Arch release? https://github.com/tinygo-org/tinygo/blob/dev/.circleci/config.yml#L368

Couldn't find any information about this so I've posted a question on the AUR forum: https://bbs.archlinux.org/viewtopic.php?pid=1914409#p1914409.

Thanks!

I could be wrong, but the way I understood https://www.oshwa.org/a-resolution-to-redefine-spi-signal-names was that the new signal names are (usually) SDO and SDI (similar to TX and RX). Additionally, I find SDO and SDI easier to understand.

It doesn't seem to be possible right now, but I've asked if it can be changed in the future https://bbs.archlinux.org/viewtopic.php?pid=1914523#p1914523.

@aykevl I like the SDO/SDI better as well. Changes made and force pushed.

@johanbrandhorst thanks for checking into it.

I think that I have now handled all of the boards currently in the dev branch. This PR should now be ready.

@deadprogram could you update the default branch?
Just spent an ungodly amount of time compiling an obsolete branch 😂

@sevki see https://github.com/tinygo-org/tinygo/blob/master/CONTRIBUTING.md#how-to-use-our-github-repository

[aykevl]

While I agree this is a good change in principle, we should be careful to use the correct terminology. I'm worried some changes may make things less clear. We can't really do this kind of thing again without good reason because it will break existing programs.

[deadprogram]

Updated again based on feedback, and also for new boards added since I started this PR.

Anything else needed for this PR?

[aykevl]

A few nits for consistency, but really it looks good to me now. Feel free to fix this (or not) and merge, LGTM.

Looks good to me, so merging. There is a CI failure but that one already existed before this PR (and should be fixed separately).
