[Pdbg] [PATCH v2 00/24] Rework sbefifo library and driver

[Amitay Isaacs]

The current implementation of libsbefifo assumes kernel device driver based
transport for sbefifo.  However, it's possible to use other transport
mechanism (e.g. cronus) to talk to sbefifo.  This is implemented by providing
connect api for specifying custom transport.

V2 changes:
 - Refactoring libsbefifo to separate marshalling routines
   (this made it easier to spot bugs in marshalling)
 - Add connect api to libsbefifo to provide custom transport
 - Split sbefifo hwunit into sbefifo and chipop hwunits
   - chipop hwunit provides all the ops previously provided by sbefifo
   - sbefifo hwunit now defines the transport and provides a method
     for accessing libsbefifo context required for chip-ops
