Log Message:
Update to version 2.0.2.  This, among a lot of other things, fix
compilation against newer OpenLDAP, as shown in bulk builds results.

Changes since 2.0.1:

Modules:
* Fixed detecting appropriate OpenLDAP libs version for
  determining whether ldap_whoami_s() is available or not.
  This fixes build problems with OpenLDAP libs 2.1.0 up
  to 2.1.12.
----------------------------------------------------------------
Changes since 2.0.0:

dsml:
* Fixed wrong exception message format string

ldap.schema.models:
* Fixed Entry.__delitem__() to delete really everything
  when deleting an attribute dictionary item.
----------------------------------------------------------------
Changes since 2.0.0pre21:

ldif:
* Empty records are simply ignored in ldif.LDIFWriter.unparse()

Modules/:
* New method result2() returns 3-tuple containing the msgid
  of the outstanding operation.

ldap.ldapobject:
* New _ldap wrapper method LDAPObject.result2() (see above)
  which is now used by LDAPObject.result().
----------------------------------------------------------------
Changes since 2.0.0pre20:

setup.py:
* runtime_library_dirs is set

Modules/:
* (Hopefully) fixed building with OpenLDAP 2.2 libs in errors.c
* Removed meaningless repr() function from LDAPObject.c
* Removed setting LDAP_OPT_PROTOCOL_VERSION in l_ldap_sasl_bind_s()
* Modified string handling via berval instead of *char
  in l_ldap_compare_ext() makes it possible to compare attribute
  values with null chars.
* Wrapped ldap_sasl_bind() for simple binds instead of ldap_bind()
  since 1. the latter is marked deprecated and 2. ldap_sasl_bind()
  allows password credentials with null chars.
* Removed unused sources linkedlist.c and linkedlist.h
* Function l_ldap_whoami_s() only added if built against
  OpenLDAP 2.1.x+ libs (should preserve compability with 2.0 libs)

ldap.ldapobject:
* LDAPObject.bind() only allows simple binds since Kerberos V4
  binds of LDAPv2 are not supported anymore. An assert statement
  was added to make the coder aware of that.
* Renamed former LDAPObject.sasl_bind_s() to
  LDAPObject.sasl_interactive_bind_s() since it wraps OpenLDAP's
  ldap_sasl_interactive_bind_s()
----------------------------------------------------------------
Changes since 2.0.0pre19:

Modules/:
* Removed doc strings from functions.c
* Removed probably unused wrapper function l_ldap_dn2ufn() since
  ldap_dn2ufn() is deprecated in OpenLDAP 2.1+
* Removed wrapper function l_ldap_is_ldap_url().
* Removed macro add_int_r() from constants.c since it caused
  incompability issues with OpenLDAP 2.2 libs
  (Warning: all result types are Integers now! Use the constants!)
* New wrapper function l_ldap_whoami_s()

ldap.ldapobject:
* New wrapper method LDAPObject.whoami_s()

ldap.functions:
* Removed is_ldap_url(). The more general function
  ldapurl.isLDAPUrl() should be used instead.

ldap.sasl:
* Added class cram_md5 (for SASL mech CRAM-MD5)

ldap.async:
* Use constants for search result types (see note about
  add_int_r() above).
----------------------------------------------------------------
Changes since 2.0.0pre18:

Modules/:
* LDAPObject.c:
  Most deprecated functions of OpenLDAP C API are not used anymore.
* functions.c:
  Removed unused default_ldap_port().
* constants.c:
  Removed unused or silly constants
  AUTH_KRBV4, AUTH_KRBV41, AUTH_KRBV42, URL_ERR_BADSCOPE, URL_ERR_MEM
* errors.c:
  Fixed building with OpenLDAP 2.2.x
  (errors caused by negative error constants in ldap.h)

ldap.ldapobject.LDAPObject:
* Removed unused wrapper methods uncache_entry(), uncache_request(),
  url_search(), url_search_st() and url_search_s()
* New wrapper methods for all the _ext() methods in _ldap.LDAPObject.

ldap.modlist:
* Some performance optimizations and simplifications
  in function modifyModlist()
----------------------------------------------------------------
Changes since 2.0.0pre17:

ldap.ldapobject:
* Fixed missing ldap._ldap_function_call() in
  ReconnectLDAPObject.reconnect()
----------------------------------------------------------------
Changes since 2.0.0pre16:

ldap.functions:
* Fixed ImportError when running python -O
----------------------------------------------------------------
Changes since 2.0.0pre15:

Modules/:
* Removed definition of unused constant RES_EXTENDED_PARTIAL since
  the corresponding symbol LDAP_RES_EXTENDED_PARTIAL seems to not
  be available in OpenLDAP-HEAD (pre 2.2) anymore.

All in Lib/:
* Fixed some subtle bugs/oddities mentioned by pychecker.

dsml:
* Renamed DSMLWriter._f to DSMLWriter._output_file
* Added wrapper method DSMLWriter.unparse() which simply
  calls DSMLWriter.writeRecord()

ldap.ldapobject:
* Simplified LDAPObject.search_subschemasubentry_s()

ldap.functions:
* Moved ldap._ldap_function_call() into ldap.functions.
* apply() is not used anymore since it seems deprecated

ldap.async:
* Added class DSMLWriter

ldap.schema:
* Removed unused key-word argument strict from
  ldap.schema.subentry.SubSchema.attribute_types()
* Fixed backward compability issue (for Python prior to 2.2) in
  ldap.schema.subentry.SubSchema.listall()
