used for lookaside cache and increase the size of the cache to use the
full allocation.

6a8ab6d9cb For the mem1.c system malloc implementation, use the malloc_usable_size() 
function if the HAVE_MALLOC_USABLE_SIZE macro is defined.  Update autoconf
to look for that function when configuring.

029ead645d If an error occurs within sqlite3_step() on a statement prepared using sqlite3_prepare_v2(), transfer both the error code and error message to the database handle before sqlite3_step() returns (so that they are available via sqlite3_errcode() and sqlite3_errmsg(). Prior to this commit, only the error code was transfered. The error message was not available until after either sqlite3_reset() or sqlite3_finalize() had been called on the statement handle.
