261919cc16 Some elements of the new malloc() failure handling. Not all cases work properly yet. Also, library is not threadsafe if malloc() fails right now. (CVS 2800)

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)

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)

91636d58c0 The --enable-cross-thread-connect configuration option or the 
-DSQLITE_ALLOW_XTHREAD_CONNECT compile-time option permits database
connections to be moved across threads.  This will cause latch-ups
and failures on some linux systems such as RedHat-9.  Do not use these
options if you want a portable build. (CVS 2778)
