* Corrected missing part of porb_h route in the caravan chip_io_alt
layout. Correcting the indexing of the "mprj_io_one" connections
to "mgmt_io_oeb" on the left-hand side of caravan, as they were
connecting back to the right side and making a mess of wiring,
instead of being wired locally directly to the nearest I/O.
* Apply automatic changes to Manifest and README.rst
* Corrected the unconnected mgmt_io_in inputs to housekeeping on
the caravan chip (which correspond to the GPIOs that do not exist
in caravan) by connecting them to the "zero" outputs of the
closest GPIO control blocks.
* Apply automatic changes to Manifest and README.rst

* Syntax changes that are non-functional from a synthesis perspective.
There are a few errors that are caught by commercial tools and halt
synthesis, which are handled more gracefully by the open source
tool flow. In housekeeping.v: Some wires declared after they are
used. In housekeeping_spi.v: A non-blocking "=" assignment used
where a blocking "<-" assignment was intended.

* Effectively reverted the change to add spare logic blocks near each
of the GPIO control blocks by changing the definition of
NUM_SPARE_BLOCKS to 4 (the original number of spare logic blocks)
for both caravel and caravan top level RTL verilog modules.
* Apply automatic changes to Manifest and README.rst

* Added enough spare logic blocks to have the existing four above
the processor, plus one each per GPIO (38 for caravel, 27 for
caravan).

This reverts commit 577cc12fe0.
Reverting the change from issue #16. After some discussion, it has
been decided that it is up to the user to implement the pull-up and
pull-down modes correctly by setting the output enable and driving
the output to the appropriate value. Note that this should be well
documented, if by nothing else than a validation testbench that
excercises a user pull-up and pull-down input mode.
* Modified the set_user_id.py script so that mode "-report" returns
a valid value, instead of throwing an error, because the "info.yaml"
file was removed without due consideration of the side effects.
* Apply automatic changes to Manifest and README.rst

* Corrects four signals which were missing from the caravan top level
(management output and output enable to GPIO 0 and 1---these errors
would have prevented the houskeeping SPI from working on caravel).
Corrected RTL verilog (source of the error), GL verilog, and layout.
* Apply automatic changes to Manifest and README.rst
