examples/fluids: Riemann outflow using pressure and temperature

* This allows stable sustained and transient recirculation.

* short-wake domain recirculation behind cylinder has sustained
recirculation. If the exterior temperature is different, the
recirculation will bring in the wrong temperature, but at least
it's stable.
* nwave with slow background causes transient flow reversal when
strong acoustic hits boundary.
* Clean outflow and lid for Blasius

* I tried the 2 P_ext - P_int strategy from Mengaldo (constant density)
and with specified exterior temperature, but they disrupted the interior
flow and were not significantly less reflective.

* The methods I tried for extrapolating interior temperature were not
stable. Simple extrapolation of velocity worked best, and did not show
signs of instability, perhaps because the neighboring flow and implicit
solve ties it together.

* This commit adds support for softmax control of recirculation, but the
parameters were finnicky, solver nonlinearity was a concern, and I'm not
convinced it's ever better than just allowing recirculation.

Merge pull request #1131 from CEED/jed/checkpoint-interval

fluids: checkpoint interval

examples/fluids: write step and time to single binary checkpoint file

The -continue and -continue_time_filename arguments can be skipped when
reading new-style files, which include the step number.

examples/fluids: write step and time to single binary checkpoint file

The -continue and -continue_time_filename arguments can be skipped when
reading new-style files, which include the step number. When reading
legacy files, all three are necessary.

This deprecates the time file.
