[v10,00/10] Extensions for PTWRITE

  From: "Willgerodt, Felix" <felix.willgerodt@intel.com>

v9 can be found here: https://sourceware.org/pipermail/gdb-patches/2023-July/200621.html

I only fixed some small comments by Eli and Tom (thanks!).
But I thought I would post it again anyway. I think what is missing
is another look from Markus and Simon on the new changes since
Simon's review of v7. Those were in patches 5, 8, 9 and 10.

Changes since v9:
* Patch 06: Added NEWS entry.
* Patch 09: Improved and new checks for return values in recpy_call_filter.
* Patch 10: Moved NEWS entry to the right section. Fixed small /doc nit..

Thanks,
Felix
