Updated some comments that still referenced the old CORDIC
implementation, which is no longer used.

White Rabbit is not supported in X410, however the register map included an
incorrect reference to this unsupported feature.
This commit removes the WR reference from both the source and html files.

This change allows assertion errors/failures in ModelSim to be
detected and causes ModelSim to return a non-zero value when such
an assertion error occurs. This allows the return value of ModelSim
to be used to determine whether or not the testbench passed.

VHDL depends on the compile order. This commit changes the order so
that SIM_SRCS are compiled last with ModelSim to avoid issues with
dependencies.

This updates the existing PART_NAME generation used in simulation
makefiles to work with newer part families by calling
viv_gen_part_id.py to generate the part name needed by Vivado.

This is a list of testbenches that don't work with ModelSim and should
be excluded when running run_testbenches.py.

This adds the MSIM_VIV_COMPLIBDIR environment variable to specify
a non-default location for the compilation libraries.
This also allows a modelsim.ini other than the one in the ModelSim
installation folder to be used. By default, the one in the simulation
libraries compilation directory will be used. This can be changed by
setting MSIM_MODELSIM_INI to the one you want to use, or set it to an
empty string to use the one in the ModelSim installation folder.

Run "make ip" in a separate step for each testbench. This allows some
testbenches to work better with ModelSim because it needs IP files that
aren't known until after the IP is generated.
Make run_testbenches.py more log friendly. Add a -l/--logged option for
when the output is being logged. In this case, we don't want to display
elapsed time every second.
Add "Begin TB Log:" and "End TB Log:" to the output to more easily tell
where the output from one testbench ends and another begins.
Use the basedir argument as the base directory in which to search for
testbenches so that a subset of the repo can be easily specified.

Update rfnoc_image_core.v to take into account the new image_core_name
fields and version strings. Add new rfnoc_image_core.vh. Update YAML
where needed.

The script setupenv_base.sh, which is used to setup the development
environmnet in the open source toolchain, adds some functions to the
shell that are used to interact with vivado. Some of the functions were
looking in the wrong argument for the product name. This commit fixes
the bug.
In addition, supplying an incorrect part name returned a rather opaque
error message. This commit also fixes the error handling so that the
intended error message is displayed.

Change version from a numeric to a string, in order to
differentiate between versions like "1.1" and "1.10".

Adds a time_increment port for situations in which the parameter
TIME_INCREMENT can't be used. They offer the same behavior.

This pipelines ctrlport_timer to eliminate the long combinational path
caused by the time comparisons. This change also removes the
PRECISION_BITS parameter and converts it to a signal named
time_ignore_bits.

Add a SystemVerilog interface for connecting AXI4 ports, and an
associated header file with helper macros.

This adds the ability to call BUILD_VIVADO_IP, as before, followed by
REBUILD_VIVADO_IP_WITH_PATCH to patch a file generated by the IP and
then rebuild the IP with the patched file.

This commit includes the following changes to the tools:
- Change part definition in XCI and BD editors for the RFSoC family
- Resolve part name in Vivado IP management utilities with
viv_gen_part_id.py

Per the RFNoC specification, if we set the frequency of flow
control updates to 0 then the input stream will not send flow control
status updates to the output stream handler.
This change makes it so that when the frequency of flow control status
updates is configured to be zero in the FPGA output stream handler
(i.e., cfg_fc_freq_bytes and cfg_fc_freq_pkts are both 0 in
chdr_stream_output) then the output stream handler will not use flow
control. That is, chdr_stream_output will not expect stream status
updates and will not restrict output packets.

The asynchronous feedback loop on the err signal causes X to get stuck
on the sum signal when simulating. This change adds a check for
simulation only to force X to 0 so that unknown inputs get resolved
once the inputs are known.
Also added default values to the ports out and strobe_out, since having
them uninitialized and without reset was causing simulation issues in
other modules. The FPGA will initialize them to 0, so this change makes
the code equivalent to real hardware behavior.

The always(*) block was never executing in some simulators because
there were no signals on the right-hand side in the block. Changing it
to an initial block ensures it always runs.
Original-commit: 0b965d579e2df962b91dac141eef6668f932e992
Removing the FIR filter in the frontend to reclaim resources and remove
redundancy when using a DDC block. The default image has a DDC block,
so only users making custom RFNoC images and using TwinRX will need to
take care to properly downconvert the full bandwidth coming from the
radio block.

- 2to3 was used to convert the Python scripts, except where the tool
choked and manual intervention was required
- All references to "python" where replaced with "python3"
- buffer() was replaced by memoryview()
