sqlite3_result_blob64(), and sqlite3_result_text64().
Add the sqlite3_msize() interface.
Internal memory allocation routines now use 64-bit unsigned
length parameters for safety.
Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid
a integer overflow problem.

When doing a full table scan on a table that has an equality constraint on
an unindexed column, do not allow the estimated number of output rows to
be greater than half the total number of rows in the table.

an alternative to the long-standing algorithm of building a lookup table.
Use the new implementation in circumstances where it is likely to be faster,
such as when the RHS of the IN changes between successive evaluations.

faster queries in some cases, for example when the RHS of the IN operator

turns out to be helpful. If the list is of length 1 or 2, the OR expression
is very slightly faster, but the ephemeral table approach is clearly better for
all list lengths greater than 2. Better to keep the code simple.
