150d457b55 ldb: Work around inconsistent behaviour in PyObject_AsMessageElement()
PyObject_AsMessageElement() has ‘flags’ and ‘attr_name’ parameters to
set properties of the returned MessageElement, but they apply only
*sometimes*.

‘attr_name’ not being set can result in cryptic and misleading error
messages from various ldb operations.

Changing the function’s behaviour to be more consistent could break
existing code, so we work around the issue instead.

5905a63307 pyldb: Raise an exception if ldb_dn_get_parent() fails
Such a failure could be caused by situations other than memory errors,
but a simple indication of failure is all that ldb_dn_get_parent() gives
us to work with.

We keep the old behaviour of returning None if the DN has no components,
which an existing test (ldb.python.api.DnTests.test_parent_nonexistent)
expects.

860d8902a9 pyldb: Make ldb.Message containment testing consistent with indexing
Previously, containment testing using the 'in' operator was handled by
performing an equality comparison between the chosen object and each of
the message's keys in turn. This behaviour was prone to errors due to
not considering differences in case between otherwise equal elements, as
the indexing operations do.

Containment testing should now be more consistent with the indexing
operations and with the get() method of ldb.Message.

e075f52a75 pyldb: fork pyldb_Ldb_AsLdbContext macro to reflect unsafeness
In the Python/C API, conversion functions which check the types of their arguments
have names like:

double PyFloat_AsDouble(PyObject *pyfloat);

while conversion macros that don't check have names like:

PyFloat_AS_DOUBLE(pyfloat)

The pyldb_Ldb_AsLdbContext() macro looks like one of the checking functions
but it actually isn't. This has fooled us more than once. Here we fork
the macro into two -- one which performs checks and keeps the camel
case, and one with a shouty name that keeps the check-free behaviour.
