Updated ha_tokudb::index_read and comparison functions based on code review.
Also put in some (very informal) comments about how index_read is supposed to work.

fix the EDOM errors by makeing the key compare function implement a total order on the key space (including key prefixes), and using DB_SET_RANGE in place of DB_SET for cursor operations.  closes #576 closes #587

file->offset(addr) were assuming addr was within the field's record, which is not always the case.  closes #592

tokudb does not implement the DB_RMW cursor get flag.  updates were gettting EINVAL fromthe storage engine. tokudb turns read locks into write locks when required, to the flag is just an optimization.  we plan on replacing the affected code with the tokudb delete both method in the future.

the old key compare function uses extra context: the bdb_return_if_eq and insert_or_update.  this will not work in tokudb as keys are compared after the insert has already completed.  

the bdb_return_if_eq will be replaced with some new cursor operations.  the insert_or_update feature applies to varchar keys (and is not compiled into the 5.1.22 code).
