Function prototypes in grib2.h repeated in g2_getfld.c, except it adds function g2_unpack2()

[edwardhartnett]

In grib2.h we have (note that unpack2 is missing):

/*  Prototypes for unpacking sections API  */
g2int g2_unpack1(unsigned char *,g2int *,g2int **,g2int *);
g2int g2_unpack3(unsigned char *,g2int *,g2int **,g2int **,g2int *,g2int **,g2int *);
g2int g2_unpack4(unsigned char *,g2int *,g2int *,g2int **,g2int *,g2float **,g2int *);
g2int g2_unpack5(unsigned char *,g2int *,g2int *,g2int *,g2int **,g2int *);
g2int g2_unpack6(unsigned char *,g2int *,g2int ,g2int *,g2int **);
g2int g2_unpack7(unsigned char *,g2int *,g2int ,g2int *,g2int ,g2int *,g2int ,g2float **);

In g2_getfld.c we have:

g2int g2_unpack1(unsigned char *,g2int *,g2int **,g2int *);
g2int g2_unpack2(unsigned char *,g2int *,g2int *,unsigned char **);
g2int g2_unpack3(unsigned char *,g2int *,g2int **,g2int **,
                 g2int *,g2int **,g2int *);
g2int g2_unpack4(unsigned char *,g2int *,g2int *,g2int **,
                 g2int *,g2float **,g2int *);
g2int g2_unpack5(unsigned char *,g2int *,g2int *,g2int *, g2int **,g2int *);
g2int g2_unpack6(unsigned char *,g2int *,g2int ,g2int *, g2int **);
g2int g2_unpack7(unsigned char *,g2int *,g2int ,g2int *,
                 g2int ,g2int *,g2int ,g2float **);
