Netatalk and AFP 3.x

It's alpha work, don't use it on a production box or on an existing volume,
it will trash filenames.
Filenames convention is subject to change.

AFP 3.0 and AFP 3.1 are OSX extensions to AFP Apple protocol.

New features:
------------
- UTF8 name
- support for files > 2 GBytes

Requirements
------------
- I think glibc2.2 or >
- a kernel with large files support.

Compilation
-----------
configure --enable-afp3

if you have an error about AC_SYS_LARGEFILE you need to upgrade yours
autoconf/automake tools.

UAMS 
----
uams_guest.so 
uams_pam.so uams_passwd.so  (clear text login)
uams_dhx_pam.so uams_dhx_passwd.so 

Configuration
-------------
afpd.conf
use only uams above with -uamlist

For volumes
add options:utf8, don't use it with codepage: but you can use mswindows

UTF8 strings
------------
-Only Mac roman to UTF8 for pre OSX
-255 bytes max.

-Decompose/precompose issue
OS X uses the decomposed form:
 latin small letter a with grave is 0x65 0x301 

iconv from Mac to UTF8 and by default NT and Linux keyboards use precomposed form:
 latin small letter a with grave is 0xe0

Filenames are saved in precomposed form and are decomposed for OSX

- It doesn't convert existing volumes to UTF8
