acf688ef2e Closes #912 
toku_db_set_* (the dbt setting functions)
no longer require atomicity for ENOMEM cases.
Also, in the case of realloc, we only alloc new memory if
the new size is larger than the old size, or the new size is less than
half of the old size.

Code has some simplifications due to lesser atomicity requirements.

Modified src/tests/test_db_dbt_mem_behavior.c to take into account
that DB_DBT_REALLOC now uses the ulen field.

e22d67bb8e Addresses #893 
Implement db->pre_acquire_read_lock(), db->dbt_pos_infty(), and db->dbt_neg_infty()
functions.

Example usage to lock entire table:
db->pre_acquire_read_lock(db, txn, db->dbt_neg_infty(), NULL, db->dbt_pos_infty(), NULL);
(Above is for db with no duplicates, i.e. primary index).

For db with duplicates:
db->pre_acquire_read_lock(db, txn, db->dbt_neg_infty(), db->dbt_neg_infty(), db->dbt_pos_infty(), db->dbt_pos_infty());

Will return same lock error codes as db calls do (when locks fail).
0 = success
DB_LOCK_NOTGRANTED = failed to obtain the lock.
We can theoretically sleep and try again here.

If you want to grab from DBT* A to infinity..
db->pre_acquire_read_lock(db, txn, A, NULL, db->dbt_pos_infty(), NULL);
