lib/talloc: Provide multiple-loading detection for libtalloc via rand()

The use of rand() is strongly discrouanged, but here is it ideal, as we 
just want to select a different
set of random bytes if we are called again within the same process.

lib/talloc: Disrupt buffer overflow attacks on Samba by using random magic

By setting the talloc magic to a random value, we make it much harder to 
overwrite a talloc_chunk
in a valid way with a simple buffer overflow.

The flags are placed before more senstive variables so they have to be 
overwritten first.

Inspired by the exploit in:

build: Move __attribute__ ((destructor)) and ((constructor)) tests to 
wafsamba

This allows us to use them in talloc as well.
