Log Message:
-----------
pp_pack: SvPV_force() pack(p/P, ...) arguments when writable
pack("p"/"P") is generally pretty awful, but we document that you
can pack("P") and then write to the pointer supplied, so make that
safer by ensuring the PV isn't shared with other SVs.
Since _force() throws on a READONLY SV, and you shouldn't be writing
to one, only _force() for a writable SV.
This is still broken when magic is involved, but we did document it
as usable.
Fixes the UUID::FFI part of #22380
Some other modules (and UUID::FFI itself, really) will need XS
fixes.
