Make 10.23.0 releasev10.23.0

 - Commit ee25489 ("menuconfig: Print '----' instead of '---> (empty)'")
   makes the menuconfig display empty menus (e.g. from disabled
   'menuconfig' symbols) in a less spammy way, matching the C tools.

 - Commit 6313925 ("Remove message re. Kconfiglib 10 backwards compat.
   break") removes an old message printed when the top-level Kconfig
   file can't be opened and $srctree is set. Hopefully it's been noticed
   by now.

 - Commit a1a4430 ("Use 'foo.__class__ is Bar' instead of
   'isinstance(foo, Bar)'") improves parsing and evaluation performance a
   bit.
