The functions strcasecmp, strncasecmp are provided by a single module:
'strcase'.
Similarly, the functions c_strcasecmp, c_strncasecmp are provided by a
single module: 'c-strcase'.
While this saves a little bit of module description and *.m4 code, it
has two drawbacks:
- It blurs the usual correspondence of 1 function = 1 module.
- It causes 2 compilation units to be compiled even when only one of
them is needed.
These patches straighten the situation, by creating a new module for
each of these functions. Of course, the modules 'strcase' and 'c-strcase'
remain functional, for backward compatibility.
