Merge RTTI changes from packages branch (including adjustments that were required due to changes in trunk since then). These changes favor source backwards compatibility in contrast to Delphi compatibility. Binary compatiblity is however drastically broken due to the indirect references that are platform independant!

Merged revision(s) 28239-28289 from branches/svenbarth/packages:
Provide the possiblity to switch between the direct and indirect RTTI symbols.

ncgrtti.pas, TRTTIWriter:
  + get_rtti_label, get_rtti_label_ord2str & get_rtti_label_str2ord: add new "indirect" parameter and pass that along to rtti_mangledname
hlcgobj.pas, thlcgobj:
  * g_incrrefcount, g_initialize, g_finalize, g_array_rtti_helper: for now pass along False to get_rtti_label()
ncgvmt.pas, TVMTWriter:
  * writevmt: for now pass along False to get_rtti_label()
ncgld.pas, tcgrttinode:
  * pass_generate_code: for now pass along False to the get_rtti_label*() methods
........
Provide possibility to select between using a direct and an indirect RTTI reference. This way the references can be changed for selected cases.

ncgrtti, TRTTIWriter:
  * ref_rtti: new "indirect" parameter that's relayed to rtti_mangledname()
  * write_rtti_reference: new "indirect" paramater that's relayed to ref_rtti()
........
Switch properties to use the indirect type information without breaking backwards compatiblity. :)

compiler/ncgrtti.pas, TRTTIWriter:
  * published_properties_write_rtti_data: use the indirect reference, not the direct one
rtl/objpas/typinfo.pp:
  * to allow compilation with both 2.6.x and 2.7.1 and too avoid too many ifdefs at least in the declarations we define a macro TypeInfoPtr which is either PTypeInfo (2.6.x) or PPTypeInfo (2.7.1 and newer)
  * TPropInfo: rename PropType to PropTypeRef and change type to TypeInfoPtr
  + TPropInfo: add a new property PropType which returns a PTypeInfo out of the PropTypeRef depending on the compiler version
........
Switch further simple types (sets, enums, class references, pointers) to indirect type information (again without breaking backwards compatibility).

compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data:
  * enumdef_rtti, setdef_rtti, classrefdef_rtti & pointerdef_rtti: write an indirect RTTI reference

rtl/objpas/typinfo.pp, TTypeData:
  * rename BaseType to BaseTypeRef, CompType to CompTypeRef, InstanceType to InstanceTypeRef and RefType to RefTypeRef and change their type to TypeInfoPtr
  + add properties BaseType, CompType, InstanceType & RefType which return a PTypeInfo out of the corresponding *Ref field depending on the compiler version
........
Switch class and interface parent as well as extended type to indirect type information

compiler/ncgrtti.pas, TRTTIWriter:
  * write_rtti_data.objectdef_rtti.objectdef_rtti_class_full: use indirect reference for class parent and extended type
  * write_rtti_data.objectdef_rtti.objectdef_rtti_interface_full: use indirect reference for interface parent

rtl/objpas/typinfo.pp, TTypeData:
  + add new method DerefTypeInfoPtr which returns Nil if the indirect reference is Nil and otherwise returns the dereferences indirect reference (for 2.6.x the direct reference is returned as is)
  * rename ParentInfo to ParentInfoRef, HelperParent to HelperParentRef, ExtendedInfo to ExtendedInfoRef, IntfParent ot IntfParentRef and RawIntfParent to RawIntfParentRef and change their type to TypeInfoPtr
  + introduce ParentInfo, HelperParent, ExtendedInfo, IntfParent and RawIntfParent properties that return a PTypeInfo and use the new DerefTypeInfoPtr to return the correct type info value
  * change the other newly introduced properties of TTypeData to use DerefTypeInfoPtr as well to be on the safe side
........
Switch record/object fields to indirect type information references.

compiler/ncgrtti.pas, TRTTIWriter.fields_write_rtti_data:
  * use the indirect reference for the object parent type
  * use the indirect reference for the field type

rtl/inc/rtti.inc:
  * TRecordElement: change TypeInfo to PPointer for 2.7.1 and newer
  * RecordRTTI: correctly dereference the element type for 2.7.1 and newer
  * fpc_copy: correctly reference the element type for 2.7.1 and newer
........
Switch static arrays to indirect RTTI reference.

compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data:
  * arraydef_rtti: write the dimension types and the final field type as indirect references

rtl/inc/rtti.inc:
  * TArrayInfo: switch ElInfo to PPointer for 2.7.1+
  * ArrayRTTI & fpc_copy: correctly dereference ElInfo for 2.7.1+
rtl/objpas/typinfo.pp, TArrayTypeData:
  * switch ElType and Dims to PPTypeInfo; no backwards compatibility needed here as TArrayTypeData was added in 2.7.1 only

tests/test/trtti8.pp: fix test
........
Switch dynamic arrays to indirect RTTI references.

compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data.arraydef_rtti:
  * write indirect references for the two element entries

rtl/inc/dynarr.inc:
  * tdynarraytypedata: change elType2 to PPointer for 2.7.1+
  * fpc_dynarray_clear, fpc_dynarray_setlength & fpc_dynarray_copy: correctly dereference elType2 for 2.7.1+
rtl/objpas/typinfo.pp, TTypeData:
  * rename elType and elType2 to elTypeRef and elType2Ref respectively and change type to TypeInfoPtr
  * add properties elType and elType2 which return PTypeInfo by dereferencing elTypeRef and elType2Ref respecively correctly
  * remove a few stray "inline" directives in the implementation
........
Switch procedure parameters and result type to indirect RTTI references.

compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data.procvardef_rtti:
  * write_procedure_param: use indirect RTTI reference
  * write result info for both methods and procvars as indirect RTTI reference
  * write parameters for procvars as indirect RTTI reference

rtl/objpas/typinfo.pp:
  * TProcedureParam: change type of ParamType to PPTypeInfo (no backwards compatiblity needed here; was added for 2.7.1)
  * TProcedureSignature: change type of RseultType to PPTypeInfo (no backwards compatibility needed here; was added for 2.7.1)
  * TTypeData: remark in the comments of tkMethod that ResultTypeRef and ParamTypeRefs are of type PPTypeInfo and not PTypeInfo

tests/test/trtti9.pp: 
  * fix test
........
Remove no longer needed "indirect" parameter for TRTTIWriter methods.

ncgrtti.pas, TRTTIWriter:
  - ref_rtti & write_rtti_reference: remove "indirect" parameter
  * ref_rtti: call rtti_mangledname with "indirect" always set to "true"
  - remove "true" parameter on callsites of write_rtti_reference & ref_rtti
........
