It is possible to reduce to a value that is not a dict in "insert_item()"
and "update_item()". Raise a ServerError with a clear description of
what went wrong in these situations.

It is possible that Moonraker can be instantiated while the eventloop
is running during tests. To avoid errors allow synchronous calls until
the server starts.

Now that all transactions run in a thread it is possible for them to
interleave. The record based operations allow for batch operations
within a single transaction.

Wrap command implementations in with a _run_command() method. All
database commands now return a Future object. If the command was
run before the eventloop starts its possible to immediately query
the Future's result.

Similar to the update method, however sync will remove any
keys in the database not in the new value.

Rather than creating two wrappers, use a single wrapper whose methods
always return a future or awaitable. If the operation occurs during
the __init__() method of a component it will be syncrhonous, and the
result from the future can be immediately queried.

Rather than reading out the entire database, attempt to pop off
empty keys in each database. This should should speed up
init on platforms with slow disk I/O and prevents reading
large namespaces in memory.

It isn't necessary to read out the entire namespace, just attempt
to fetch the record and reduce the key list.

Since transactions are now threaded we need updating
and clearing a namespace needs to be performed within
one transaction.

Database transactions can perform disk I/O tasks, which at times will
block the eventloop. Run all transactions in threads to prevent this
from occuring.

Keep track of the number of unsafe shutdowns a machine experiences. This data is useful in diagnosing potential file system issues and issues with the datbase itself.

It is invalid for a namespace to contain a top level key represented as an empty bytestring. If this is detected, log the result and drop the invalid key.

A Moonraker component may now register a namespace as "forbidden". API requests have no read/write access to forbidden namespaces and this cannot be overridden by the database debug option.

This allows protected namespaces to be modified externally. This is for dev use only, modifying protected namespaces can potentially corrupt the database.

This fixes a bug where it is protected namespace can be modified in an optional component if that component is disabled.
