bae591a960 Merge the latest trunk changes into shared-schema branch. Also fix a C99-ism 
in that branch.

9c67b2aae0 Add the mode=memory option to URI filenames, which when present forces the 
database to be an in-memory database.  This enables named in-memory databases.

4ab9d254e0 Only allow :memory: databases to share cache if there are created using a 
URI filename.  This minimizes the risk of breakages in legacy applications
that have shared-cache enabled but also use :memory: databases which they
expect to keep separate.

5efb314525 Avoid using sqlite3ResetAllSchemasOfConnection() purely for its side-effects.

81028a455d The former sqlite3ResetInternalSchema() routine was really two different 
routines, selected by parameter, each with a confused mission.  So split
this routine up into three separate smaller routines, calling each
separately as needed.  Hopefully this will make further refactoring and
schema reset collateral damage containment easier.
