Testing with multiple python versions can be done by testing a full compile against

Commit 88ae60ed18 introduced a problem that made one-level
searches inefficient if there were a lot of child objects in the same
level, and the requested object didn't exist. Basically, it ignored the
case where ldb_kv_index_dn() returned LDB_ERR_NO_SUCH_OBJECT, i.e. the
indexed lookup was successful, but didn't find a match. At which point,
there was no more processing we needed to do.
The behaviour after 88ae60ed18 was to fall-through and run the
ldb_kv_index_filter() function over *all* the children. This still
returned the correct result, but could be costly if there were a lot of
children.
The case 88ae60ed18 was trying to fix was where we could not do
an indexed search (e.g. trying to match on a 'attribute=*' filter). In
which case we want to ignore the LDB_ERR_OPERATIONS_ERROR and just run
ldb_kv_index_filter() over all the children. This is still more
efficient than the fallback of doing a full database scan.
This patch adds in a short-circuit for the NO_SUCH_OBJECT case, so we
can skip the unnecessary ldb_kv_index_filter() work.

While 'es' format works great for unicode (in python2) and
str (in python3) The behaviour with str (in python2) is unexpected.
In python2 the str type is (re-encoded) with the specified encoding.
In python2 the 'et' type would be a better match, that ensures 'str'
type is treated like it was with 's' (no reencoding) and unicode is
encoded with the specified encoding. However in python3 'et' allows
byte (or bytearray) params to be accepted (with no reencoding), we
don't want this. This patch adds a new PYARG_STR_UNI format code which
is a hybrid, in python2 it evaluates to 'et' and in python3 'es' and
so gives the desired behaviour for each python version.

No matter commit succeeded or failed, transation will be delete afterwards.
So there is no need to delete it here.
Aganst Samba this causes an `LDAP error 51 LDAP_BUSY` error when the transaction
fails, say while we try to add users to groups in large amount and
the original error is lost.
In Samba, the rootdse module fails early in the del part of the
start/end/del pattern, and in ldb_tdb and ldb_mdb a failed commit
always ends the transaction, even on failure.

ldb attributes are either bytes (py3) or str (py2)
Some places in the code do str(res[0]['attribute'][0])
which results in
'result' (py2)
b'result' (py3)
or more commonly the attribute is used to construct a string e.g.
"blah=" + res[0]['attribute'][0] + ",foo,bar=...."
giving
"blah=result,foo,bar=...." (py2)
and very unhelpfully
"blah=b'result',foo,bar=...." (py3)
lots of code already constructs various strings for passing to other
api using the above. To avoid many excessive
res[0]['attribute'][0].decode('utf8')
code like 'res[0]['attribute'][0]'
will now return LdbBytes (a new object subclassing 'bytes') in py3
instead of bytes. This object has a custom '__str__' method which
attempts to return a string decoded to uft8. In Py2 this will behave as
it did previously (this is the safer option at the moment)

We need to enforce the GUID index mode so end-users do not get a

that the index key trunctation is done correctly.
Otherwise the DB will appear to work until a very long key (DN or
index) is used, after which it will be sad.
Because the previous ldb_lmdb_test confirmed the key length by
creating a large DN, those tests are re-worked to use the GUID index
mode. In turn, new tests are written that create a special DN around
the maximum key length.
Finally a test is included that demonstrates that adding entries to
the LMDB DB without GUID index mode fails.

string type. However now it's quite possibe the content formally passed
as a string argument is now passed as unicode after being decoded,
such arguments are rejected and code can fail subtly. This only affects
places where the type is directly checked e.g. via PyStr_Check etc.
