[PATCH] talloc: Add ifdef'd extern "C" to ease use in C++ projects.

[Kenneth Graunke]

Currently, if one wishes to use talloc in a C++ program, one has to write:

extern "C" {
#include <talloc.h>
}

This patch takes care of that in talloc.h so C++ programmers can simply write:
#include <talloc.h>

This is much nicer, especially since forgetting the extern results in obscure
linker errors.  C programs should be unaffected by this patch.
