Macros RTF_GETx and RTF_PUTx

Depending on settings in file Rtfcfg.h, RTF_GET16, RTF_GET32, RTF_PUT16, and RTF_PUT32 expand either to macros or to function calls. They can be used to access little-endian and potentially misaligned data in FAT data structures which have type RTF_U16 or RTF_U32.

typedef struct { 
   BYTE B[2]; 
} RTF_U16; 

typedef struct { 
   BYTE B[4]; 
} RTF_U32; 

WORD  RTF_GET16(const RTF_U16 w); 
DWORD RTF_GET32(const RTF_U32 d); 

void  RTF_PUT16(RTF_U16 & dest, WORD w); 
void  RTF_PUT32(RTF_U32 & dest, DWORD d);

Types RTF_U16 and RTF_U32 are not used on little-endian platforms which can access misaligned data (such as x86), so the use of these macros is not required here.
