ABI: add no-corpus-path flag + Update ABI files with generated in CI worker

[gmelikov]

Motivation and Context

• storeabi: add no-corpus-path flag: just try to minimize diffs
• update ABI files with generated in CI worker: so next updates will have smaller diffs

Description

ABI was generated on latest master via CI https://github.com/gmelikov/zfs/actions/runs/1042626752

Additional notes:

After #12379 we can generate ABI description files with smaller diffs.

Unfortunately, further optimizations may be brought only with fresh libabigail, which is not in our CI and stable OS distros yet. For example, I 've found --no-comp-dir-path was only introduced since 1.7, which is pretty new https://pkgs.org/download/abigail-tools . Good example of latest abigail usage: https://android.googlesource.com/kernel/build/+/c494508%5E%21/

Someone may prepare Docker image with needed abigail-tools, but it's not one-liner to get it work with CI and other machinery (it has to work on compiled binaries).

Let's wait a little, and ask everybody to commit .abi files from CI.

How Has This Been Tested?

CI will validate it.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Performance enhancement (non-breaking change which improves efficiency)
• Code cleanup (non-breaking change which makes code smaller or more readable)
• Breaking change (fix or feature that would cause existing functionality to change)
• Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
• Documentation (a change to man pages or other documentation)

[gmelikov]

So, for future changes in storeabi routine we may regenerate description files in separate commit to minimize new diffs later. In this case actual ABI changes will be granular.

Thanks! It's a shame some these new options aren't available from the distributions just yet.
