drh 2e9d706252 Remove the (undocumented) query-planner control that prevents 
a "SELECT ALL" subquery in FROM clause from being implemented as a co-routine.

drh 4e6cec1ca0 Fix an issue introduced by check-in [4cd2a9672c59] (2017-03-03) that could 
allow a negative value in the 3rd parameter to memmove() when
defragmentPage() is called on a btree page with a corrupted
freeblock list.  The corruption is now detected early and results in
an SQLITE_CORRUPT return before the memmove() is reached.

LIKE optimization only works for the built-in LIKE operator and ICU overrides
the built-in.

extra space at the end of the record blob as an overrun area to use when
decoding a maliciously malformed record.

line of the Fossil-generated "manifest" file in the SHA3 hash.  That means
that all SQLITE_SOURCE_IDs for trunk versions going back to
check-in [30966d56] (2017-08-22) are incorrect.
