* Changed genmodule so that now no .ref needs to be generated when the
functionlist section is present in the .conf file. The syntax of the
functionlist has changed now so that the function prototype is present and
this results in a syntax similar to the function list in a .sfd file.
* A function can now be made private by adding a line containing .private
after the prototype in the functionlist
* .cfunction specification has to be added after a function that has
register based argument passing for the outside API of the library but is
declared as a normal C function internally (e.g. not using the AROS_LH
macros). A stub function will then be generated that converts the arguments
passed in registers to C type argument passing.
* Adopted %rule_genmodule_files and %rule_genmodule_incldes in
config/make.tmpl so that no ref file is generated when not needed.
* Changed oss.conf and freetype2.conf so that they now use the new syntax
for the functionlist. freetype2.lilbrary now also uses the tagcall generated
from genmodule
* Internally in genmodule now the argument type is not separated from the name anymore.
Only when spitting out AROS_LH macros these are separated. This should allow
to use function pointers as a function argument when the AROS_LH support it
(but this is not the case at the moment).
