[PATCH] Document talloc with doxygen

[Andreas Schneider]

Hi tridge,

I've finished the talloc documentation. I've used a trick to hide the macros 
and present them as functions. You should use the latest doxygen release to 
generate the documentation. Currently html and manpages are created.

You can take a look at the html output at:

http://www.cynapses.org/tmp/samba/talloc/

I've integrated everything from the talloc homepage so that you can replace 
the html file on talloc.samba.org with the documentation.

You can pull from here:

http://gitorious.org/samba/gladiac-wip/commits/talloc

I've started to document tevent now.

Greetings,
