b2a0f75c06 Remove the rarely-used scratch memory allocator. This makes the code smaller, 
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.

184d902db1 In the kvtest.c test utility, reuse the buffer into which blobs are read, 
rather than reallocating it for each row.  This is a closer match to how
other test programs work, and thus provides a better comparison.

befcd8ad84 Add option "--stats" to test program kvtest. Specifying --stats causes kvtest 
to output information similar to the shell tool option of the same name.

cae20d5cf1 In kvtest.c, use stat() instead of fseek()/ftell() to determine the size of 
a BLOB to be read directly from disk.  This makes the pile-of-files database
more competative against SQLite.
