42d2fce7f5 Provide the SQLITE_DIRECTONLY flag for app-defined functions that prohibits 
the use of those functions within triggers or views.

2e6d83bc49 Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not 
NULL is a pointer to a database connection which seeds the connection from
its schema cookie.  In this way, fuzzers can control the PRNG seed.

some branch instructions can never take the NULL path and that the OP_Jump
opcode is only interested in equal/not-equal.  The
SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly
differently (it provides the callback with a bitmask of the branch action,
rather than an integer).
