- Modernize the format of the open file showing mode output:

Browse Source 
. Print the column headers centered (except for the left-aligned
     TYPE header) using a different header for architectures where
     sizeof(uintptr_t) is not four.
   . Consistently do not print a '0x' prefix for hexadecimal values.
   . Separate columns by a single space character.
   . Pad the columns presenting an address or offset enough to hold
     their respective largest value.
   . Do not restrict the output to unknown file types, inodes and
     sockets; allow displaying of pipes, fifos, kqueues and crypto file
     descriptors too.
 - Shorten an overly long line by removing a cast of printf's return
   value to void.
