4ec502a7f6 a) Refactor sort module. All related sort_work_file management moved into TempSpace class now. Former sort_work_file is now TempSpace::Segment 
b) Add parameter names to declarations of TempSpace methods. It make sources much more readable, i believe, and allow IntelliSense to make useful hints
c) Reworked sort module to use more memory for merge buffers. It significantly increased speed of large sorts. Memory mostly reused from TempSpace memory blocks

b3dcfede36 Close external table's file when relation is not used by the engine. 
This is simplest fix for bug CORE-132 (Restore fails on external table) and CORE-961(Free external tables)

b94c6d20e5 Misc: 
- DSC_EQUIV is no longer a macro; no need to wrap arguments in extra parenthesis.
- Make reinterpret's explicit.
- No need to cast dsc_address to UCHAR* since it's already of this type.
Hope I didn't screw someone.
