f0e9a2a081 Fix PutBlock after Release bug
There is logic in the broadcast hub to skip the outer acquire if there
is an outgoing release, since the data will be written out through the
release channel. However, this will cause an issue in the case of
PutBlock requests. If the tail beats of the PutBlock show up after the
outer release has already been sent, the data will be corrupted.

The fix is to make the outer release block if there are pending
inner PutBlock beats.

a5ac106bb8 axi4 ToTL: fix decode error arbitration (#417)
When selecting between error generation on R and real data on R,
correctly calculate the R backpressure.

This bug manifests when a valid request is immediately followed by
an invalid request, wedging the R channel.

f382ee70da Sanity check compile-time vs simulation-time options
If user compiles without +define+DEBUG but then requests +vcdfile at
simulation time, that request would be silently ignored. This changes
it to a fatal error.

It's good philosophy to treat plusargs like +vcdfile as commands, not
suggestions, and die immediately if they cannot be honored, instead of
silently ignoring them. Otherwise the user sits through the entire
simulation and then is left scratching his head wondering where his
waveforms are.

9f0fda01b3 Fix Cadence Incisive compile warning
The SystemVerilog LRM (IEEE 1800-2012) clause 20.15.1 ($random
function) says: "The seed argument shall be an integral variable."

This fixes the following compile warning:

    rand_value = $random($urandom);

ncelab: *W,WRNOTL (/home/scottj/rocket-chip/vsrc/TestDriver.v,34|23): Argument to out parameter is not a legal lvalue.
