1) NULLs on top when sorting on ASC index, DESC stays the same.
2) Support for larger index lengths, can be up to 1/4 page size.
3) Store record-number on non-leafpages for faster lookup in many duplicates.
4) Jump-nodes for faster key-lookup in index on larger page-sizes.
5) Segment selectivity calculation added.
-Replace codes.h with iberror.h (or remove)
-Move gds__vax_integer and gds__event_block* to alt.cpp and isc_ to gds.cpp
-Use ISC_QUAD internally
-Use isc_vax_integer internally
placed some variables in context
fixed some function signatures
closed a few possible buffer overruns
sorry to the platform maintainers, I can't verify what I did for non-Win32 builds
- Include service entrypoint in each proto file and remove from it the private function common to service and standalone. (burp, alice and gsec)
- Replace functions output_svc/output_thread/output_netware with SVC_output callback common for all. (burp, alice and gsec)
- Create typedef pfn_svc_output common for all svc, and correct SVC_read_ib_log and thread_test to be compatible with pfn_svc_output typedef. (svc.cpp)
- Put inside an ifdef code for '-svc_re' switch (in all sources).
