Valentin Tolmer e8f7155d98 grammar: record used associativity and print useless ones ...

Record which symbol associativity is used, and display useless ones.

* src/symtab.h, src/symtab.c (register_assoc, print_assoc_warnings): New
* src/symtab.c (init_assoc, is_assoc_used): New
* src/main.c: Use print_assoc_warnings
* src/conflicts.c: Use register_assoc

Due to the new warning, many tests had to be updated.

Add the associativity warning in the expected results.
* tests/java.at: Fix the java calculator's grammar to remove a useless
associativity.
* doc/bison.texi (mfcalc example): Fix associativity to remove
warning.
