translate: use compositional suspension on request

Browse source 
This has to be turned on using "-x comp-susp" and other
related options documented in spot-x (7).

* src/tgbaalgos/translate.hh, src/tgbaalgos/translate.cc:
Add support for calling composition-suspension, with
optional simulation, WDBA-minimization, and composition.
* src/bin/spot-x.cc: Document the new options.
* src/bin/man/spot-x.x: Add some bibliography.
* src/tgbatest/ltlcross2.test: Test it.
