ea36c3a938 db: collapse the db_queries files into the generated ones
There's no reason to have these be independent of the generated files,
all the data contained within them is 'formulaic'

fcf3d0ce6c db: turn generated queries array into a simple hash table.
Since we have that functionality, let's use it.  Also, make table
const.

787fbb1228 db: create simple hashtable of fields in SELECT.
This simplistically maps names to numbers, eg:

	SELECT foo, bar FROM tbl;

'foo' -> 0
'bar' -> 1

If a statement is too complex for our simple parsing, we treat it as a
single field (which currently it always is).

15b403531e db: Allow DB-specific queries in the migrations
Sometimes we need some DB-specific magic, and marking migrations with
`/*PSQL*/` or `/*SQLITE*/` will now give us that.

36b66871a2 db: add min/max commitnum fields to channel_htlcs.
And initialize max to current height max when htlcs are already dead.
Turns out (thanks CI!) that MAX() of multiple columns is GREATEST() in
Postgres.  That's clearer (MAX is used elsewhere for single columns),
so translate on the sqlite3 side.

a150b09665 wallet: Add new htlc column "localfailmsg" for outgoing htlcs.
We're going to change our internal structure next, so this is preparation.
We populate existing errors with temporary node failures, for simplicity.

4c2f51ce13 Fix syntax error in sql-rewrite.py
On python 3.4.2 having kwargs after unpacking
a dict in a function call seems to be a syntax
error.

2ddf168d59 db: Implement SQL statement rewriting
We now have an abstract rewriter that will perform some common extractions and
replacements (type replacement for example), that can then be customized in
derived classes.

640e64cb73 db: Switch statement lookup to use the original query instead
Using a generated identifier with filename and line proved to be brittle since
compilers assign the __LINE__ macro differently on multi-line macro
invocations.

70e8da4fbd wallet: Add read-only flag to extracted queries
This gets rid of the two parallel execution paths of read-only and write
queries, by explicitly stating with each query whether it is a read-only
query, we only need to remember the ones marked as write queries.

e4ab98459c wallet: Add tooling to extract SQL queries and generate driver info
This is the counterpart of the annotations we did in the last few commits. It
extracts queries, passes them through a driver-specific query rewriter and
dumps them into a driver-specific query-list, along with some metadata to
facilitate processing later on. The generated query list is then registered as
a `db_config` and will be loaded by the driver upon instantiation.
