 * reduces templates count
 * leaves only one lexical converting class (at least for modern compilers)
 * fixes small TODOs and XXXs from source code
 * makes lexical_stream_limited_src more readable
 * updates status/explicit-failures-markup.xml
 * makes lexical_cast_inf_nan_test.cpp pass on Itanium pltform
 * makes lexical_cast able to convert signed and unsigned chars to wchar_t
 and updates lexical_cast_wchars_test
