e8601c6561 Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by 
check-in [1a1cf5aa86734c8].  That check-in was to remove harmless
compiler warnings.  So once again, we have introduced a real bug
into SQLite by attempting to eliminate a harmless compiler warning.

5b15b75ada In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8).

58a450c041 Treat identifiers in the HAVING clause the same as in the WHERE clause. 
Only consider AS names from the result set to match if there are no other
matches.  Continuation of the fix for [2500cdb9be05].  This check-in
fixes a bug found by [http://www.sqlite.org/sqllogictest/ | SqlLogicTest]
during release testing for version 3.7.17.
