* spot/twaalgos/gfguarantee.cc: Rework the history computation to keep
an overapproximation of the history, and a longer one. Also replay
the history even if there is no initial trivial SCC. This helps with
translating FG(!a|XXXb) where we need to keep the history of a, but we
were previously unable to do so because some state had both "a" and
"ab" as input.

automata by removing useless trivial SCCs.

interface of spot::fixed_size_pool

Annotate pools with valgrind macros so that it detects errors in pool
usage. Typically, we wish valgrind to detect a leak when the user fails
to call proper deallocation function.
* spot/misc/fixpool.hh, spot/misc/mspool.hh: here

* tests/core/gragsa.test: Add another formula to cover more
code.
Related to issue #351.
* spot/twaalgos/sccfilter.cc: When handling weak automata, we know
they are very-weak if the SCC count is equal to the number of states.
* tests/core/dca2.test, tests/core/monitor.test,
tests/core/parity2.test, tests/core/randomize.test,
tests/core/readsave.test, tests/core/remfin.test,
