    afs: add afsd -inumcalc option
    
    This commit adds the afsd -inumcalc command line switch to specify the
    inode number calculation method in a platform neutral way.
    
    Inode numbers reported for files within the AFS filesystem are generated
    by the cache manager using a calculation which derives a number from a
    FID. Long ago, a new type of calculation was added which generates inode
    numbers using a MD5 message digest of the FID.  The MD5 inode number
    calculation variant is computationally more expensive but greatly
    reduces the chances for inode number collisions.
    
    The MD5 calculation can be enabled on the Linux cache manager using the
    Linux sysctl interface.  Other than the sysctl method of selecting the
    inode calculation type, the MD5 inode number calculation method is not
    specific to Linux.
    
    This change introduces a command-line option which accepts a value to
    indicate the calculation method, instead of a simple flag to enable MD5
    inode numbers.  This should allow for new inode calculation methods
    in the future without the need for additional afsd command-line flags.
    
    Two values are currently accepted for -inumcalc. The value of 'compat'
    specifies the legacy inode number calculation. The value 'md5' indicates
    that the new MD5 calculation is to be used.
