[Bug-readline] [PATCH] hide symbols for helper xmalloc/xrealloc/xfree functions

[Robert Millan]

Hi!

libreadline is exporting symbols for its internal helper
xmalloc/xrealloc/xfree functions.  These function names are
quite common, but might not behave exactly the same way as
readline expects.

Attached patch fixes the problem by adding a "hidden" attribute to
them.

I'm also attaching a test case.
