Released 3.1.0 2018-05-25

This release brings two minor API changes:

- Long-deprecated functions `ldap.open()` and `ldap.init()` are removed

- `LDAPObject.compare_s()` and `compare_ext_s` return bool instead of 0 or 1

All changes since 3.0.0:

* Remove long deprecated functions ldap.open() and ldap.init()

* Make iteration over cidict yield same values as keys()

* Fail if pyasn1 is not installed

* Fix parsing of PPolicyControl ASN.1 structure

* Use items() when appropriate in dict iteration

* Add support for tracing LDAP calls. Tracing can now be enabled with

the env var PYTHON_LDAP_TRACE_LEVEL and redirected to a file with

PYTHON_LDAP_TRACE_FILE.

(This is mainly intended for debugging and internal testing; the

configuration or output may change in future versions.)
