fdd6e85a34 Initial infrastructure for recognizing DESC indices and being able to read

them.  Nothing is close to working yet. (CVS 2822)

054889ec6d Restructure the OS interface yet again. This time make the OsFile object 
a virtual base class which is subclassed for unix, windows, and the crash
test simulator.  Add the new file "os.c" for common os layer code.  Move
all OS-specific routines into the sqlite3Os structure. (CVS 2795)

9cbe635219 Make the OsFile structure opaque with its internal structure known only to 
the appropriate os_*.c implementation.  Omit the os_unix.h and os_win.h
include files.  The crash tests are broken by this patch. (CVS 2791)

9c06c95309 Modify the OS layer so that I/O routines are called through a virtual function 
table.  The os_test.c module has been replaced by test6.c.  The crash tests
are busted now and need to be fixed. (CVS 2785)

0342b1f542 Sorting is now done using a sorting index rather than loading the entire 
result set into memory and doing a merge sort.  The old merge sort technique
was a carry-over from SQLite version 1.  The new method uses a bounded amount
of memory and scales to much larger result sets.  There are still errors:
some 39 regression tests fail. (CVS 2653)
