2d98e95ec0 On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() 
after writing N bytes of content, to force a write-queue flush in the
underlying OS.  This is an experimental hack that is not expected to land
on trunk.

6d7ec6a1d0 Fix another point in zonefile.c so that all files are opened in either "rb" or 
"wb" mode.

4e8f3bbd95 When calling fopen() in the zonefile extension, use modes "rb" and "wb" 
instead of "r" and "w". This makes no difference on unix, but is required when
accessing binary files on other systems.

f313952097 Improve the performance of the built-in REPLACE() function in cases where 
it does many substitutions that make the string larger.  OSSFuzz is reporting
intermittant timeouts when running a test where it does a REPLACE() on a 
930KB random blob. Perhaps this enhancement will fix that.

eab0e10304 In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound 
to persistent SQL statements using SQLITE_STATIC, the binding is replaced with
an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer
to the persistent statement using sqlite3_next_stmt() and attempt to access
the freed buffer using sqlite3_expanded_sql() or similar.
