Kalle Olavi Niemitalo 62d6db44aa Bug 381: Make codepage data const.
Before:

   text	   data	    bss	    dec	    hex	filename
  25726	  62992	   3343	  92061	  1679d	src/intl/charsets.o
 653856	 120020	  82144	 856020	  d0fd4	src/elinks

After:

   text	   data	    bss	    dec	    hex	filename
  60190	  28528	   3311	  92029	  1677d	src/intl/charsets.o
 688320	  85556	  82112	 855988	  d0fb4	src/elinks

So 34464 bytes were moved from the data section to the text section
and should be more likely to get shared between ELinks processes.
