  Modified files:
    lib/libc/string      swab.c 
  Log:
   - Convert the function definition to declare its arguments
     in the ANSI-C format.
   - Change the code a bit to hopefully save some cycles.
     I.e. (simplified) change
  
       a = b + 1;
       while (--b & 0x7)
          /* ... */
     to
       a = b;
       for (; b & 0x7; b--)
          /* ... */
     and
       while (--a >= 0)
          /* ... */
     to
       for (; a > 0; a--)
          /* ... */
   - Equip two function arguments of swab() with the 'restrict'
     type qualifier in form of the '__restrict' macro.  This is
     specified by POSIX.1-2001.
