Code is cleaner now with less special cases, handles DB_DBT_(MALLOC|REALLOC|USERMEM) as well as no flags now.
Closes #144

We never touch ulen.  If DB_DBT_USERMEM and ulen is too small, we set size, (do not write anything)
and return DB_BUFFER_SMALL.

This includes test_db_dbt_mem_behavior.c

mixing toku_malloc and malloc is not a problem.  At least with BUFFERED_MALLOC not defined.  Added a test, and a {{{#error}}} inside {{{memory.c}}}.  Fixes #161.

and pruning stale records in secondary databases.
Closes #144
Closes #158
Fixed bug where we modify key or pkey or data if we return errors and
we really just pruned stale records.

Added test to verify we have no memory leaks caused by these issues.

There was a bug in brt.c which checked to see if the number of pinned pages is zero at the beginning of a lookup.  With an open cursor, that doesn't have to be true.

Fixes #64, #141.
