Clean up a few bugs in the bytes implementation
Clean up a few bugs in the bytes implementation

A few functions were renamed but not updated in the bytes implementation in
Buffers.chpl. Give them the right names.

A bytes constructor was using the wrong name for one of its fields.  It was
also assigning c_nil to the same field with type "qbytes_ptr_t". Fix the name
and change the nil assignment to use QBYTES_PTR_NULL.
