As I'm going to be away for most of the tree stabilisation period I'm
trying to be proactive clearing my maintainer backlog before the
softfreeze. With that in mind heres what is ready to go in:

Testing

Most stuff is being directly applied as downstreams stop working (c.f.
BSD and MacOS breakage). So all I have left is a fix for qos-tests
that shows up when LTO is enabled.

GDBStub

These are Ilya's fork follow mode patches for gdbstub. I hope to
include Gustavo's signal handling stuff if it is fixed this week.

Plugins

This introduces Pierrick's work to have thread-safe inline counters
via the concept of a vcpu indexed scoreboard. There will be further
work over the next cycle to enable more efficient instrumentation and
address more of the missing pieces people have been asking for.

Finally there are a few cosmetic patches to ensure the disassembly
that plugins get don't include opcodes which plugins can get another
way. They are the only patches that need review:

  target/riscv: honour show_opcodes when disassembling
  target/loongarch: honour show_opcodes when disassembling
  disas/hppa: honour show_opcodes
  disas: introduce show_opcodes

Hopefully I can get the PR for this rolled later this week.

Alex.
