Missing braces arround extern declarartions in __SET_EXTERNAL define was making problem with GCC in switch case statements

Moved __INIT_* defines within type definition headers files

Fixed warning in accessor __SET_EXTERNAL

Fixed bug when defining task with single_data_source instead of interval_data_source

Merged Mario's changes

Fix bug related to FB invocation of FB instances declared as VAR_EXTERN.

Merged Mario's changes

Partial fix to VAR_EXTERN vs VAR_GLOBAL check. Now considers globals declared in resources too. TODO: recursively check FB declared in the program.

Allow variables declared inside resources to be referenced by res_name.var_name

Add a new node to the abstract symtax tree, which will let us do datatype checking of FB variable declarations using the standard algorithm, and no special cases.

Print filename when debugging abstract symbol table.

Consider fb_name_decl_c a non base data type class!

Fill symbol->datatype anotation for FB declarations.

Fill in the symbol.datatype annotation in symbol classes used in derived data type declarations.

Use simple_spec_init_c inside en_param_declaration_c (will reduce need to handle it as a special case in the future).
