Add option to open database in read-only mode
...
With read-only it's not possible to modify the data. Updates to the data
are possible via a primary instance of oxigraph, but will not be
reflected. The data is frozen at the time the read-only server is
started.

Add option to open rocksdb in secondary mode
...
The database can be opened once in primary mode, but may be opened
multiple times in secondary mode. It's not possible to write data to the
database in secondary mode.
Secondary mode does not support checkpoints so there might be data
inconsistencies when data is changed while said data is queried. It
might happen that the result data mixes both elements before and after
the change that can not happen in primary mode.

Implements SEP-0002 ADJUST function

SPARQL UPDATE: Fixes Halloween problem
...
Buffers all SPARQL UPDATE operation for DELETE/INSERT in order to avoid this problem.
This is quite heavy but RocksDB transaction already stay in memory, hence it won't change a lot the operation complexity.
The unit test for this problem was bad because the optimizer was hiding the problem.
