complete transition to locale independant core operation

The netsurf core no longer uses any locale dependant operations
excepting the mall number or cases where such operations are
explicitly wanted.

the netsurf_init now calls setlocale with the empty string and lets
the c library setup as per its specific implementation.

any core functionality that specificaly processes ascii text must use
the utils/ascii.h header to do so.
