Support wide character strings

- "string" lens and "format" pack were extended such that using an
  integer as underlying array type denotes a wide character string.

- several prototypes from wchar.h were added to libc.so.conf.

- ltrace.conf.5 was updated

+    This is useful in particular for:
+
+    | ulong mbsrtowcs(+string(array(uint, zero(arg3))), string*, ulong, addr); |
+
+    Where we would like to render arg2 on the way in, and arg1 on the

     But sometimes we may want to see a different type on the way in and
     on the way out.  E.g. in asprintf, what's interesting on the way in
     is the address, but on the way out we want to see buffer contents.
