Code cleanup (part 3): generate_c_typedecl_c is no longer needed for code generation in POUS.c It is now only needed for datatype declaration in POUS.h

Code cleanup (part 2): generate_typedecl_c now only prints to POUS.h !

Code cleanup (part 1): subrange check functions are now declared in POUS.h (as static inline functions or #define)

Fix get_datatype_info_c::is_subrange(), which did not work when using base type! (we now use get_equivtype() instead of get_base_type() )

fix a couple of typos.

Fix bug - correctly declare struct members whose type is a directly defined array (e.g.: STRUCT x: ARRAY of XXX; END_STRUCT)

Start using the called_fb_declaration annotation when generating C code from FB calls in ST.

Code cleanup: move datatype analysis to get_datatype_info_c

Fix bug-fix of previous commit.

Fix bug: allow use, as lvalues, structures/arrays inside FBs (e.g. fb1.struct1.r := 33.3).

Fix bug/issue #33 (correctly access struct/array variables declared inside a FB -> r:=FB1.FB2.struct1.array1[3] )

Add assertion suggested by Manuele.

Use get_datatype_info_c::is_type_valid() to determine datatype validity
(some datatype bugs in source code were going unreported!)

Recursively check the datatype compatibility of values/expressions passed in function/FB invocations.
