drh 31999c5cac Fix a bug in the hard_heap_limit pragma so that it returns the new value of
the hard_heap_limit, not the soft_heap_limit.  Change SQLITE_MAX_MEMORY so
that it works by setting the default hard_heap_limit value.

drh 4a7e9a25b6 Set a low limit on the length of strings and blobs in the OSSFuzz module,
in an effort to avoid timeouts when the fuzzer does things like
"randomblob(1e12)".

drh 8055a3ead4 Improvements to the ossfuzz.c fuzz-testing module so that it works with
-DSQLITE_OMIT_PROGRESS_CALLBACK and with -DSQLITE_OMIT_INIT.

drh 56f1774603 Make the shell functional even if compiled with SQLITE_OMIT_COMPLETE.
Omit the sqlite3_complete() call from the fuzzing interface if it is
compiled with SQLITE_OMIT_COMPLETE.

drh 93bbfbe539 Prevent OSSFuzz from using debugging pragmas that are disabled in default builds
and which generate lots of excess output.

drh 174f855306 Add the --native-malloc option to fuzzcheck. Fix ossfuzz.c and fuzzcheck.c
so that they both deallocate the temp_store_directory before closing.

drh 544cab7651 Set a reasonable limit on the number of opcodes in a prepared statement
for ossfuzz.c.  This should prevent timeouts in OSS-Fuzz when it generates
totally unreasonable queries.

drh bbc0177460 In the OSSFuzz test module, invoke the progress handler much more frequently
so that timeouts are detected punctually even if the test script is running
opcodes that individually take a long time (for example, an OP_Function opcode
that invokes "randomblob(1.5e6)").

drh a6bf20b587 Fix an error in the SQLITE_MAX_MEMORY implementation resulting from a bad
merge.  Update the OSSFuzz interface so that it times out after running
the byte-code engine for 10 seconds.

"PRAGMA empty_result_callbacks=1;".  Add the ossshell.c program for
simple command-line testing of ossfuzz.c.
