- Added stdio thread locking functions flockfile(), funlockfile(),

and ftrylockfile().

- Modified the internal FILE structure to allow for thread locking.
  Note that this again requires that the library is rebuilt!

- Added or modified macros for getc_unlocked(), getchar_unlocked(),
  putc_unlocked() and putchar_unlocked().

- Added rand_r().

- Added flockfile()/funlockfile() wrappers around all stdio
  functions.
