WT-1315. Added support for join cursors:

- "join:" URI handling added to WT_SESSION::open_cursor, added WT_SESSION::join.
- Added support for in-memory bloom filters.
- Minor fix to cur_dump_close CURSOR_API_CALL.
- Some refactoring in __wt_{curindex,curtable}_get_value() to allow them
    to be called internally.
- Use new macro JOINABLE_CURSOR_API_CALL() instead of CURSOR_API_CALL()
    to trap illegal calls to joined cursor.
- __wt_curtable_open now takes an owning cursor arg.
- Added __wt_struct_unpack_size() and __wt_struct_repack()
