The whole file-system interface is pluggable - at runtime
if you compile with -DSQLITE_ENABLE_REDEF_IO, or at compile-time
by default. Three different interface modules come with the
code: Unix, Win32, and OS/2. It is not that much trouble to
write a new one for your in-process read-only database. Use
the other three OS interface modules as your guide. You can
skip most of the implementation since you only need read-only.
