d427bd6c77 ldb: Move where we update the pack format version
Store it on the repack context so that we can log a more informative
message "Repacking from format x to format y".

While this is not really a big deal currently, it could be worth
recording for potential future scenarios (i.e. supporting three or more
pack versions), where upgrades could potentially skip an intermediary
pack format version.

a2b0fc7c00 ldb: Always log when the database pack format changes
LDB_DEBUG_WARNING gets logged by Samba as level 2, whereas the default
log level for Samba is 0. It's not really fair to the user to change the
format of their database on disk and potentially not tell them.

This patch adds a log with level zero (using a alias define, as this
technically isn't a fatal problem).

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.

652258768a ldb key_value: Add batch_mode option
When performing a join the overhead of the sub transactions protecting
key value operations becomes significant.  This commit adds a new
"batch_mode" option that disables the sub transactions around key value
operations.

The operation level index cache is also disabled, which means the
overall transaction level index cache can become inconsistent if an
operation fails. To protect against this and other possible on disk
inconsistencies, if any operation fails during a batch_mode
transaction the commit will fail and transaction will be rolled back.
