gdbstub: extend GByteArray to read register helpers
...
Instead of passing a pointer to memory now just extend the GByteArray
to all the read register helpers. They can then safely append their
data through the normal way. We don't bother with this abstraction for
write registers as we have already ensured the buffer being copied
from is the correct size.

Similarly to what we already do with qdev, use a helper to overload the
reset QOM methods of the parent in children classes, for clarity.

Remove unassigned_access CPU hook
...
All targets have now migrated away from the old unassigned_access
hook to the new do_transaction_failed hook. This means we can remove
the core-code infrastructure for that hook and the code that calls it.

exec: Factor out cpu_watchpoint_address_matches
...
We want to move the check for watchpoints from
memory_region_section_get_iotlb to tlb_set_page_with_attrs.
Isolate the loop over watchpoints to an exported function.
Rename the existing cpu_watchpoint_address_matches to
watchpoint_address_matches, since it doesn't actually
have a cpu argument.
