3b8eb08b17 Better than removing the incorrect assert() is to change it into a 
testcase() together with a comment indicating where an appropriate test case
can be found, and the ticket that provoked the change.
Ticket [614b25314c766238]

d8df36bd4e Change the zipfile virtual table so that the xBestIndex method gives a 
reasonable cost estimate even if no filename is specified.  The missing
filename error continues to be raised in the xFilter method.  Meanwhile,
the more reasonable cost estimate avoids unnecessary wierdness in the query
planner.

ffe4d4a2d5 New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and 
sqlite3_filename_wal().  Also sqlite3_uri_key().  And the other sqlite3_uri
functions now work using the journal or wal filename in addition to the
database file.  And the sqlite3_db_filename() result is guaranteed to work 
as an argument to the sqlite3_uri functions.

8875b9e7b5 Rearchitect the way in which filenames are stored in the Pager object so that 
the sqlite3_uri_parameter() interface will work from journal and WAL filenames
too.  This check-in implements the central idea, and compile and runs somewhat,
but crashes on an extended test.
