C++11 remove std::unary_function bases from functors

std::unary_function is deprecated since C++11 and removed in C++17

90% done with regexp magic.
removed obsolete <functional> includes.

The std::unary_function base class was used in 3 places:
* chart2/source/tools/DataSeriesHelper.cxx: lcl_MatchesRole
is used in a std::not1 function helper who uses the members
return_type and argument_type.
- replace deprecated std::not1 with a lambda
* chart2/source/tools/ModifyListenerHelper.cxx:
lcl_weakReferenceToSame used the argument_type member in the
operator() parameter.
- inline the parameter type.
* xmloff/source/chart/SchXMLExport.cxx: lcl_SequenceToMapElement
used result_type and argument_type in operator().
- inline the types

Also fix compile error with gcc about finding std::for_each.
