Pulled chisel-miscutils.

* miscutils, packaging are subprojects which are depended upon
* configured correspondingly in build.sbt, removed symlinks in src
* defined metadata for build artifact (incl. version)
* updated .gitignore to ignore temp files in subprojects

6d4e97b Add build.sbt to define artifact

* AXI4Lite interface
* flexible ControlRegister class hierarchy: constants, single values,
  virtual registers (callbacks)
* implemented unit test cases
* had to implement Axi4LiteProgrammableMaster for batch testing

* muxes N AXI-MM masters to one AXI-MM slave
* read and write channels are mux'ed independently
* no interruptions during bursts, next schedule on LAST
* address valid is used to signal transfer requests
* may cost up to N-1 cycles latency

* renameSignals on AXI bundle should support prefix and suffix in order
  to accomodate multiple instance of the interface in one module

* configurable sliding window module with AXI DMA backend
* uses AxiFifoAdapter internally to retrieve data from AXI slave
* shifts with Decoupled interface
* generic module for arbitrary bitwidths / data types

* has method to fill AxiSlaveModel with structured data for testing

* moved config params into sealed case class
* unified constructors to use new config object
* added companion object for convenience constructors (backward
  compatible)
* changed constructor calls in unit tests accordingly

* size parameter indicates automatic address wrapping
* no need for resets in between (not always feasible)
* wraps on overflow to current value of `base` input

* new methods allow getter access via address or index
* set method supports writing at address

* addresses should only be handshaked when data is actually avaiable /
  needed; previous logic would provide addresses as fast as possible
* this fixes problems with handshaken addresses at other modules when
  adapter is being reset

* opposed to FifoAxiAdapter, addresses may only be supplied via the
  interface if data will be read (slave will supply data)
* this bug led to erroneous read bursts, overflowing the buffer
* fixed some minor condition issues

* addressess in transactions should be supplied as fast as possible
* waiting for the transaction to finish is not necessary and harms
  performance
* not sure if this implementation is ok; there could be a large gap
  between address handshake and data - if this blocks the slave it
  must be fixed (further tests required)

* asserts cause unit test to fail w/o VCD dump

* replaced tick-tock-buffers with single FIFO
* burst size now independent of buffer size
* bursts start immediately when FIFO has space for one burst
* operation similar to FifoAxiAdapter
* unit tests work unchanged

* considering the significant delays for real-world rw access
  to memory, AxiSlaveModel should have optional delays to sim
  that behavior
* extracted config to AxiSlaveModelConfiguration class
* adapted existing unit test suites
* bugfix in Axi2AxiSuite: afa now waits for writes to finish
