    MakeLibrary -- construct a library

    library = MakeLibrary(vectors, structure, init, dSize, segList)
    D0                    A0       A1         A2    D0     D1

    struct Library *MakeLibrary
                          (APTR,struct InitStruct *,APTR,ULONG,BPTR);

    This function is used for constructing a library vector and data
    area.  The same call is used to make devices.  Space for the library
    is allocated from the system's free memory pool.  The data portion of
    the library is initialized.  init may point to a library specific
    entry point.

    Starting with V36, the library base is longword adjusted.  The
    lib_PosSize and lib_NegSize fields of the library structure are
    adjusted to match.

    vectors - pointer to an array of function pointers or function
            displacements.  If the first word of the array is -1, then
            the array contains relative word displacements (based off
            of vectors); otherwise, the array contains absolute
            function pointers. The vector list is terminated by a -1
            (of the same size as the pointers).

    structure - points to an "InitStruct" data region.  If NULL,
            then it will not be used.

    init -  If non-NULL, an entry point that will be called before adding
            the library to the system.  Registers are as follows:
                    d0 = libAddr    ;Your Library Address
                    a0 = segList    ;Your AmigaDOS segment list
                    a6 = ExecBase  ;Address of exec.library
            The result of the init function must be the library address,
            or NULL for failure.   If NULL, the init point must manually
            deallocate the library base memory (based on the sizes stored
            in lib_PosSize and lib_NegSize).

    dSize - the size of the library data area, including the
            standard library node data.  This must be at leas
            sizeof(struct Library).

   segList - pointer to an AmigaDOS SegList (segment list).
             This is passed to a library's init code, and is used later
             for removing the library from memory.

    library - the reference address of the library.  This is the
              address used in references to the library, not the
              beginning of the memory area allocated.  If the library
              vector table require more system memory than is
              available, this function will return NULL.
