Hello,

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

* Found out that one issue I was having with gdbserver was caused by an
  incompatibility it has with zsh (sourceware bug 26116).
* Fixed a gdbserver crash in my code where a register set was NULL in
  the target description.
* Now working on an issue where the target description says SVE isn't
  supported, but the regsets information says they are. This is caused
  by my code sometimes moving the first ptrace call to get the inferior
  registers to a time before it is properly stopped.

# Sourceware bug 28561 - [gdb/testsuite] Error due to not reading \r\n
  at end of mi prompt

* Set up a few containers and KVM guests to attempt to reproduce this
  bug on different environments. Reproduced it successfully on an
  openSUSE Leap 15.3 guest, as well as Ubuntu 20.04 and 22.04 containers
  in said guest. I wasn't able to reproduce on Ubuntu 20.04 nor 22.04
  guests. Suspecting it's a kernel issue where the fix was backported to
  the Ubuntu kernels.
