kgv cda06ac0e3 0029152: Coding Rules - eliminate GCC compiler warnings -Wmisleading-indentation when using MinGW
OSD_File::myFileHandle/myIO pair is now switched within class definition
instead of myFileHandle_is_only_for_Windows/myFileChannel_is_only_for_Linux macros.

OSD_Directory/OSD_Disk/OSD_File methods implementation of WinAPI/non-WinAPI
has been merged within .cxx file and reformatted.
Resolved several inconsistences on handling invalid input
between WinAPI/non-WinAPI implementations.
NCollection_Array1 is now used in several places instead of
raw memory allocation (HeapAlloc()/HeapFree()/new/delete).
TCollection_ExtendedString is used instead of StringCchCopyW.

Unused field OSD_Disk::myQuotaSize and not implemented methods OSD_Disk::*Quota*() have been removed.

Obsolete code fragment "for Visual Age compiler" is removed.
Macro __try is undefined before redefinition on MinGW to avoid warning.
