pmemblk_set_zero()(DEPRECATED), pmemblk_set_error()(DEPRECATED) - block management functions

       The  pmemblk_set_zero() function writes zeros to block number blockno in persistent memory resident array
       of blocks pbp.  Using this function is faster than actually writing a block of zeros since  libpmemblk(7)
       uses metadata to indicate the block should read back as zero.

       The pmemblk_set_error() function sets the error state for block number blockno in persistent memory resi‐
       dent  array  of  blocks  pbp.  A block in the error state returns errnoEIO when read.  Writing the block
       clears the error state and returns the block to normal use.

       On success, pmemblk_set_zero() and pmemblk_set_error() return 0.  On error, they return -1 and set  errno
       appropriately.
