xstrdup, xtrndup: allow NULL argument

Accept NULL argument in xstrdup and xtrndup functions to allow use
of "xstrdup(str)" instead of "str ? xstrdup(str) : NULL".

* xmalloc.c (xstrdup, xstrndup): Handle NULL argument.
* xmalloc.h: Add comment regarding this deviation from the behaviour
of the POSIX counterparts of these functions.
