Added character set support to mod_auth_LDAP to allow it to

convert extended characters used in the user ID to UTF-8
before authenticating against the LDAP directory. The new
directive AuthLDAPCharsetConfig is used to specify the config
file that contains the character set conversion table.

Backported to v2.0 from v2.1
