* who.c: Rename UTMP to UTMP_FILE for compatibility with SysV
utmp.h. Include some additional header files.
(main): Recognize some options from SysVr3 who. Call usage.
Set new global var `program_name' from argv[0].
(usage): New function.
(who): If -q given, only print count of users logged on.
(print_entry): New function to format an entry on the output;
make format more like that of the Unix who programs.

output field.
(who, who_am_i): Call print_entry and print_heading.
(valid_entries): New function to return count of nonempty
