11caf4f4b7 In cases where a readonly_shm client cannot take the DMS lock on the *-shm 
file, have it parse the wal file and create a wal-index to access it in heap
memory.

dea5ce36f5 Avoid locking shm-lock WAL_READ_LOCK(0) during recovery. Doing this allows 
recovery to proceed while a readonly_shm connection in unlocked mode has an
ongoing read transaction.

92c02da33e If a readonly_shm connection cannot map the *-shm file because no other 
process is holding the DMS lock, have it read from the database file only,
ignoring any content in the wal file.

fca23557fe Reactivate query flattening when the result set of the outer query has 
no function calls or subqueries.  This is a partial reversal of 
check-in [c9104b59].  Co-routines are still preferred if the outer
query has a complex result set, but for simple results sets, query flattening
is used.  Check-in [4464f40ccd7] is completely backed
out due to this change.
