This required adding support for *reading* out of the event cache, for
the sqlite backend. This paves the way for the next PR (reload from the
cache), and it should also help with testing at the `EventCacheStore`
trait layer some day.
Allows to save media in a different path than the state store.
This adds a "last_access" field to the SQLite implementation, to prepare
for future work on a media retention policy.
This removes the IndexedDB media cache implementation, because as far as
I know it is currently unused, and I have no idea how to implement
efficiently the planned media retention policy with a key-value store.
Closes#1810.

This patch introduces a new `chunk_large_query_over` function. Imagine
there is a _dynamic_ query that runs potentially large number of
parameters, so much that the maximum of parameters can be hit. Then,
this function is for you. It will execute the query on chunks of
parameters.
`chunk_large_query_over` uses `Vec::split_off` to avoid cloning `Key`s
as much as possible. It's difficult to use references here because of
the async nature of `SqliteObjectExt::prepare`.
This patch updates `get_kv_blobs`, `get_room_infos`,
`get_maybe_stripped_state_events_for_keys`, `get_profiles`,
`get_user_ids`, and `get_display_names` to use this new function.
This patch finally adds the `repeat_vars` function to replace in a
more efficient way the `vec!["?"; n].join(", ")` pattern. There is less
memory allocations.
Since stripped and non-stripped room infos use the same types,
the separation is not necessary anymore.

The SQLite crypto store uses rmp_serde to serialize all the data we're
going to store. This works nicely for most things, one exception to this
is the OutboundGroupSession type.
The OutboundGroupSession type stores to-device requests to ensure that
the session doesn't get used before it is shared with the whole group
and to ensure that the to-device requests get restored if the
session gets restored after an application restart.
The to-device requests type critically contain `Raw<AnyToDeviceEvent>`,
the `Raw` type here being the serde_json::Raw type. rmp_serde seems to
serialize this just fine, but later deserialization fails.
We're avoiding the issue by using serde_json to serialize the
OutboundGroupSession.
