Newer Jupyter version are able to capture the system's stdout and
stderr to display it in the notebook. This is done asynchronously,
with a thread polling those file descriptor. While this will help us
debug (finaly we can see the tracing code we put in C++) this causes
two issues for testing. One is the asynchronous behaviour, which
makes it very hard to reproduce notebooks. The second issue is that
older version of Jupyter used to hide some of the prints from the
notebook, so it is hard to accommodate both.
In the case of the ltsmin-pml notebook, loading the PML file from
a filename used to trigger a compilation silently (with output on the
console, but not in the notebook). The newer version had the output
of that compilation spread into two cells.
* python/spot/ltsmin.i: Work around the issue by triggering the
compilation from Python, and capturing its output explicitly, so it
work with all Jupyter versions. Also adjust to use the more recent
and simpler subprocess.run() interface, available since Python 3.5.

Adjust some comments.
"Strategy" was used for mealy machines and game strategies a like.
Introduced the notion of mealy machine in three different flavors:
mealy machine: twa_graph with synthesis-outputs
separated mealy machine: mealy machine and all transitions
have conditions of the form (bdd over inputs)&(bdd over outputs)
split mealy machine: mealy machine that alternates between
env and player states. Needs state-players

not display source filename in user facing errors. Use GNU-style
"file:line: " prefixes for locations. Adjust all sscanf() calls
to check for ignored trailing data. Add some missing checks about the
order of input and output names, checks that output names do no
intersect input names. Fix incorrect line number for unexpected
input variable number, and avoid using std::stoi as that throws
an std::invalid_argument on parse error.
* tests/python/aiger.py: Add test cases for each error message.

traditional dot syntax, indenting the output, adding some hard-coded

an example of horizontal layout.

structure contains only synthesis stuff. Also rename "solver" to
"algo" to match the ltlsynt option.

synthesis_info.
