Reason for LINK_MAX set to 32K?

Mainly because di_nlink is an int16_t in ufs/dinode.h and ufs/inode.h. 
I think it could have been bumped up to an int32_t in UFS2, but it's
probably too late now.  You might be able to change it to a uint16_t to
raise the limit to 64K, but I don't know if the kernel ever relies on a
negative link count at any time.
