* external Vivado/Vivado HLS processes only log to files
* for debugging it would be helpful to have the stdout and stderr of the
  processes log directly in the console
* added ProcessLogger for the outputs; trace level, should only be
  activated selectively

Update BlueDMA and MSIxIntrCtrl to the newest versions

See merge request !5

    - PCIE Burst Length 64
    - FPGA Burst Length 256
    - Alignment 32 Bytes
    - Fixes SUPPORTS_NARROW_BURST parameters
    - Adds NUM_READ_OUTSTANDING and NUM_WRITE_OUTSTANDING to help
    interconnects decide on the DMA features

* memory usage estimates are based on numbers reported by the
  Lichtenberg cluster, but are too conservative for normal users
* removed check for memory entirely

Adds 'sbt assembly' as necessary step to exeute tapasco.

See merge request !4

Allow evaluation of kernels using primitives provides as .ngc-files;

See merge request !3

Ports changes of the ATS Branch of TPC to Tapasco

See merge request !1

* more detailed logs for each event, easier for debugging
* also provides a rough idea of current progress during bughunt

* another bug appeared, fixed
* cleaned code, added more verbose output to log

* address map code did not work correctly, fixed

* netlist-only IP cores lead to problems with the clock constraints
  regarding the bus interfaces: Vivado could no longer infer the clock
  for each AXI interface automatically, leading to broken cores
* removed netlist creation; deactivation of OOC builds in 2016.4+ fixes
  the core problem of synthesizing the same core dozens of times

* ZipUtils now has flatten option for unzip (set by default)
* if not set, will recreate directory structure in target dir

* evaluation was too pessimistic for many cores, leading to designs
  significantly slower than possible
* fixed by using more aggressive synthesis options
* more aggressive pnr options had no measurable effect on WNS
* using new options in both evaluation and compose

* alternatives are now checked and built, in case the alternatives
  dimension is activated in DSE
