* BuildCallFrom16Func
*
* Build a 16-bit-to-Wine callback glue function.
*
* The generated routines are intended to be used as argument conversion
* routines to be called by the CallFrom16... core. Thus, the prototypes of
* the generated routines are (see also CallFrom16):
*
* extern WORD WINAPI PREFIX_CallFrom16_C_word_xxx( FARPROC func, LPBYTE args );
* extern LONG WINAPI PREFIX_CallFrom16_C_long_xxx( FARPROC func, LPBYTE args );
* extern void WINAPI PREFIX_CallFrom16_C_regs_xxx( FARPROC func, LPBYTE args,
* CONTEXT86 *context );
*
* where 'C' is the calling convention ('p' for pascal or 'c' for cdecl),
* and each 'x' is an argument ('w'=word, 's'=signed word, 'l'=long,
* 'p'=linear pointer, 't'=linear pointer to null-terminated string,
* 'T'=segmented pointer to null-terminated string).
*
* The generated routines fetch the arguments from the 16-bit stack (pointed
* to by 'args'); the offsets of the single argument values are computed
* according to the calling convention and the argument types. Then, the
* 32-bit entry point is called with these arguments.
*
* For register functions, the arguments (if present) are converted just
* the same as for normal functions, but in addition the CONTEXT86 pointer
* filled with the current register values is passed to the 32-bit routine.
