[PATCH] process MOD_EXT_VISIBLE like other MOD_FUN_ATTRs

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

The function attribute 'externally_visible' is processed
like a sort of storage modifiers but there is no reason
for it (other than to avoid the problem with function
attributes when returning a pointer) and can now be
processed like the other function attributes.

Fix this by processing it like other attributes modifiers
and adding MOD_EXT_VISIBLE to MOD_FUN_ATTR.
