Log:
  correct readlinkat(2) return type
  
  r176215 corrected readlink(2)'s return type and the type of the last
  argument.  readlink(2) was introduced in r177788 after being developed
  as part of Google Summer of Code 2007; it appears to have inherited the
  wrong return type.
  
  Man pages and header files were already ssize_t; update syscalls.master
  to match.
