This commit looks large, but its really mostly a cleanup step.
1. introduce proper error handling for the return values of fcntl and the fbtl_posix_lock function
2. rename a parameter to more accurately reflect what it does
3. introduce an mca parameter in the fs/ufs component that allows to control
what the level of locking the user would like to enforce
4. move the initialization of the fs_block_size parameter from fs/ufs into the
common/ompio component. An fs component might be allowed to overwrite this
value, but none of the actual fs components do that.

bytes written for individual operations. For collective operations, this is
unfortunately not possible.
