0ede9ebec7 Improvements to compile-time-option hygiene. Use "#if OPTION" instead of 
"#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work.
Add the "Have-Not" configuration in releasetest.tcl which disables all of
the "HAVE_component" compile-time options.

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.

7f5a7ecd21 When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to
