See issue: [#2718](https://github.com/matrix-org/dendrite/issues/2718)
for more details.
The fix assumes that if the number of transaction items are different,
then the txnid should be different.
txnid := OriginalServerTS()_len(transactions)
The case that it doesn't address is if the txnid generated this way is
the same for 2 different batches of events which have the same
OriginalServerTS and the same array length.
Another option:
txnid := OriginalServerTS()_hash(transactions)
Would love to hear other ideas and ways to fix this.

This PR refactors the app services component. It makes the following changes:
* Each appservice now gets its own NATS JetStream consumer
* The appservice database is now removed entirely, since we just use JetStream as a data source instead
* The entire component is now much simpler and we deleted lots of lines of code 💅
The result is that it should be much lighter and hopefully much more performant.
* Specify interfaces used by appservice, do half of clientapi
* convert more deps of clientapi to finer-grained interfaces
* Convert mediaapi and rest of clientapi

* BREAKING: Make eduserver/appservice use userapi
This is a breaking change because this PR restructures how the AS API
tracks its position in Kafka streams. Previously, it used the account DB
to store partition offsets. However, this is also being used by `clientapi`
for the same purpose, which is bad (each component needs to store offsets
independently or else you might lose messages across restarts). This PR
changes this behaviour to now store partition offsets in the `appservice`
database.
This means that:
- Upon restart, the `appservice` component will attempt to replay all
room events from the beginning of time.
- An additional table will be created in the appservice database, which
in and of itself is backwards compatible.
* Return ErrorConflict
* s/QueryBackfill/PerformBackfill/g
* OutputEvent now includes AddStateEvents which contain the full event of extra state events
* Only include adds not the current event
* Get adding state right
* Consolidation of roomserver APIs
* Comment out alias tests for now, they are broken
* Wire AS API into roomserver again
* Roomserver didn't take asAPI param before so return to that
* Prevent roomserver asking AS API for alias info
* Rename some files
* Remove alias_test, incoherent tests and unwanted appservice integration
* Remove FS API inject on syncapi component
* Implement gomatrixserverlib.HeaderedEvent, which should allow us to store room version headers along with the event across API boundaries and consumers/producers, and intercept unmarshalling to get the event structure right

* SQLite support for appservice
* SQLite support for mediaapi
* Copyright notices
* SQLite for public rooms API (although with some slight differences in behaviour)

* Mostly not-bad support for SQLite in syncapi (although there are problems where lots of events get classed incorrectly as backward extremities, probably because of IN/ANY clauses that are badly supported)
* Update Dockerfile -> Go 1.13.7, add build-base (as gcc and friends are needed for SQLite)
* Implement GET endpoints for account_data in clientapi
* Nuke filtering for now...
