liba is an adhoc libc.
  
  Warning: you must call "liba_init()" before using liba.
  
  We need a very small subset of the functionality provided by the standard C
  library. We could use an available libc implementation, but those are usually
  way too large and may have problematic licenses.
  
  It wouldn't even be fair to call liba a libc at all since it doesn't come close
  to implementing a significant portion of the standard. However, we do need some
  functionality usually provided by libc, so instead of reinventing the wheel we
  just implement the same entities (types, functions, etc…).
