7f6fae1f66 Extract ABC results in the order of assigned_cells. 
Currently the order of extraction can vary based on which ABC runs finish first. That's
nondeterministic, therefore bad. Instead, force the processing to happen in the same order
as `assigned_cells`, i.e. the same order we use when not using parallelism. This should
make everything deterministic.

Note that we still allow ABC runs to complete out of order. Out-of-order results are
just not extracted until all the previous runs have completed and their results
extracted.

4fc782ef2b Make ABC_DONE detection more robust. 
1) Change token from ABC_DONE to YOSYS_ABC_DONE to be a bit more robust against false matches.
2) Emit the token from the sourced script so that we don't have to worry about it showing up in the echoing
of the command as it executes. It will only appear in ABC stdout when it executes, i.e. when
our script has completed.
3) `set abcout` doesn't actually switch ABC to line buffering on stdout, since HAVE_SETVBUF is not actually
set in ABC builds in general. So stop using that. ABC does the necessary flushing when
`source` has finished.

2de641d051 Don't redirect spawned ABCs' stderr to our pipe. 
popen() doesn't do this and we should emulate the behavior of popen() as much as possible.

8492c49f6c Remove string_buf by making log_signal() and log_const() return std::string 
We only have to fix one caller in-tree so this probably has very low impact on out-of-tree plugins.
