more tests for libdb btree page split on zero index
Enhance btree debugging output somewhat to limit key printout to the
key length if the key is not null-terminated.
Add additional test case for the zero-index page split bug; test case
can create a corrupted btree database with records unreachable by
random access but reachable by sequential access. Requires
recompiling with CPPFLAGS='-DDEBUG -DDEBUG_IDX0SPLIT' to correctly
model mpool page reuse that would be present in production conditions.
(CPPFLAGS=-DDEBUG would otherwise explicitly overwrite the contents of
reused pages.)
