[ros-diffs] [ion] 20414: Fix kernel-mode executive atom implementation (mostly add SEH and tidy up the code). Then fix kernel32 implementation which was sending incorrect sizes, and also re-factored the entire code, since most functions were quatriplicated. now there are 3 main functions instead of 12. Also fixed a bug in RtlCreateAtomTable.

Fix kernel-mode executive atom implementation (mostly add SEH and tidy
up the code). Then fix kernel32 implementation which was sending
incorrect sizes, and also re-factored the entire code, since most
functions were quatriplicated. now there are 3 main functions instead of
12. Also fixed a bug in RtlCreateAtomTable.
