[ACTIVITY] Report for week #3

Hello,

# [GNU-767] Support changing SVE vector length in remote debugging

- Continued preparing patches for upstream submission. Realised I had to document my changes to the remote protocol in the GDB manual, so did that. Also making small code cleanups and updating/rewriting patch descriptions. - Noticed I could to a small optimisation in one patch, but it would involve a lot of refactoring to move GDB-specific code so that it could also be used by gdbserver, so saved the WIP branch for later.

# TCWG CI

- Investigated failure report from yesterday's email. Reproduced on tcwg-jade-03 with a slightly different build failure, but wasn't able to make much progress¹.
