a renaming of internal objects and methods to use external names, through
there are a few small wrapper functions.

to avoid dirtying pages that are unchanged.

if they change. This prototype works some, but still has issues.

because of uninitialized padding bytes.

The function might return an offset to the main table or to an index,
depending on whether the column X would be loaded from the main table or
from the index.

column X. location(X) returns NULL if X is not an ordinary table column or
if SQLite cannot figure out the location because it is using a covering index.

defragmentPage() is called on a btree page with a corrupted
freeblock list. The corruption is now detected early and results in
an SQLITE_CORRUPT return before the memmove() is reached.

faster, and easier to maintain. In place of the scratch allocator, add the
SQLITE_CONFIG_SMALL_MALLOC configuration option that provides a hint to SQLite
that large memory allocations should be avoided.
