[Bug-gnulib] mbswidth.h fix

[Bruno Haible]

Hi,

I'm committing these changes to mbswidth.c and mbswidth.h.

I've now taken the habit to #include the .h file in the .c file at the
beginning, right after <config.h> and possibly #pragma alloca. This
has three advantages:

  1) It tells the reader where to look for general comments and
     typedefs.

  2) It makes a consistency check between the function declaration in
     the .h file and the function definition.

  3) It verifies that the .h file is self contained.

And in fact mbswidth.h was not self contained - it used 'size_t'
without #include <stddef.h>
