Split smbldap in a core file and a utility file

Add module support for configuration loading

Add a first implementation of config_ldap module to put samba configuration
on ldap

It worked on my test machine, please try it out and send bugfixes :-)

have fun,
Simo.

INSTRUCTIONS:


Just add something like  this to your smb.conf file:
        config backend = config_ldap:ldap://localhost
        config_ldap:basedn = dc=samba,dc=org

the config tree must follow this scheme:
   ou=foo, dc=samba, dc=org <- global section
   |- sambaOptionName=log level, ou=foo, ...  <- options
   |- ...
   |- sambaShareName=testlc, ou=foo, ...  == [testlc]
      |- sambaOptionName=path, sambaShareName=testlc, ou=foo, ... <- option


here is a sample ldif:
# foo, samba, org
dn: ou=foo, dc=samba, dc=org
objectClass: organizationalUnit
objectClass: sambaConfig
ou: foo
description: Test Foo

# log level, foo, samba, org
dn: sambaOptionName=log level, ou=foo, dc=samba, dc=org
objectClass: sambaConfigOption
sambaOptionName: log level
sambaIntegerOption: 10
description: log level 10 is suitable for good debugging

# testlc, foo, samba, org
dn: sambaShareName=testlc, ou=foo, dc=samba, dc=org
objectClass: sambaShare
sambaShareName: testlc
description: share to test ldap config module actually works

# path, testlc, foo, samba, org
dn: sambaOptionName=path, sambaShareName=testlc, ou=foo, dc=samba, dc=org
objectClass: sambaConfigOption
sambaOptionName: path
sambaStringOption: /tmp
description: Path for share testlc

# read only, testlc, foo, samba, org
dn: sambaOptionName=read only, sambaShareName=testlc, ou=foo, dc=samba,
dc=org
objectClass: sambaConfigOption
sambaOptionName: read only
sambaBoolOption: TRUE
description: Share testlc is read only

# guest ok, testlc, foo, samba, org
dn: sambaOptionName=guest ok, sambaShareName=testlc, ou=foo, dc=samba,
dc=org
objectClass: sambaConfigOption
sambaOptionName: guest ok
sambaBoolOption: TRUE
description: Guest users are allowed to connect to testlc share
