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)

392b3ddf2e The crash test works now, at least on unix. Untested on windows. But it never 
worked on windows before so if it still does not there is no big loss.  I am
still troubled by the current design of the OS overloading mechanism.  Expect
to see more changes. (CVS 2794)

1a23593dc0 The crash tests now compile, at least. But they get wrong results. The 
problem is fundamental and suggests I need to completely rethink how the
new OS backend should work. (CVS 2792)

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)
