Split large string section; add truncation advice
* manual/examples/strncat.c: Remove. This example was misleading, as the code would have undefined behavior if "hello" was longer than SIZE. Anyway, the manual shouldn't encourage strncpy+strncat for this sort of thing. * manual/string.texi (Copying Strings and Arrays): Split into three sections Copying Strings and Arrays, Concatenating Strings, and Truncating Strings, as this section was way too long. All cross-referenced changed. Add advice about string-truncation functions. Remove misleading strncat example.

The behavior of this function is undefined if copying takes place
