This avoids master having an older or identical LDB version
to Samba 4.15.x while it gains additional changes that may
not all be backported.

* add ldb_options_get
add a function to get the options passed in ldb connect.
* add "batch_mode" option.
This options stops sub transactions being started for key value
operations. It is intended to improve the performance in batch
operations. As it bypasses the protections on operations if an
operation fails, the entire transaction will be aborted by a commit.

* copy the ldb_options passed to ldb_connect onto the ldb_context,
making them more generally available.
* fix index buffering.
As a performance enhancement the indexes are cached in memory during a
transaction, and written to disk as part of the prepare commit. The
indexes could become corrupt in the event of a failed operation.
* fix read beyond buffer
Calling the "ldb_parse_tree" function with a filter consisting of
exactly a single space (" ") would trigger a read beyond the input
buffer.

* Default pack format changed to version 2 for GUID Indexed databases
(essentially Samba's sam.ldb). This means faster unpacking for records
with lots of attributes.
* Enforce link between all new database features, following toggling of
GUID indexing. If user toggles GUID indexing on/off, target pack format
is changed. Likewise the special ORDERED_INTEGER index format is used
(when GUID indexing on) or behaves like INTEGER (when GUID indexing off).
* Database repacked if packing format not as expected.
* In the case of MDB, since GUID indexing is mandatory, feature toggling
