drh 7b4d780b54 Use exponential buffer size growth in StrAccum, as long as the size does not
grow to large, to avoid excess memory allocation resize operations.  Also,
document the fact that setting scratch memory causes SQLite to try to avoid
large memory allocations.

drh 7f5a7ecd21 When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to
record the entire size of the allocation, not just the requested size.

ADD COLUMN) then make sure the output register is fully NULL and does not
