The sqlite3 code needed to be fixed up due to the new signature for
`lattutil_log_init`.

Even the function declarations were gated behind _lattutil_internal, the
functions can be declared static in their respective files.

The name of the table is passed in to the logger's init function.

The SQLite3 logger will create the following table if it doesn't already
exist:

CREATE TABLE IF NOT EXISTS <table> (
	timesec BIGINT NOT NULL,
	timeusec BIGINT NOT NULL,
	msgtype TEXT NOT NULL,
	msg TEXT NOT NULL
)

Of course, replace `<table>` with the name of the table.

No current plans to use `lsq_flags` in `lattutil_sqlite_query_t`, but
create the struct member in case we need it in the future.

If the consuming code doesn't pass in a logger, make life easy for the
library code by instantiating a logging object, leaving it in dummy
mode.

We'll want to eventually log any parameters, which will make this
complex enough to warrant its own function.

issue:		#2

We may want to store additional arbitrary data, specific to the
underlying implementation.

For example, when I implement libpushover-based logging, I'll want to
store a libpushover context object in the logger context. I don't want
that exposed to the application, though.

Applications that consumes these objects may want to attach arbitrary
data to them. The liblattutil library will never make use of these
members.

This just gets the rows and columns by IDs. A follow-up commit will

This commit provides a unified API for performing SQLite3 queries.
Queries that return rows store their resulting data in a libucl object
tree.

Using libucl enables us to do some pretty powerful things, like convert
a SQLite3 database to JSON as one example. We can construct complex
object trees, clone objects, etc.

Not all data types are supported--only the ones I myself need right this
very moment. A more complete data type support will follow later as the
need arises.

The dummy log is the default and is effectively a NOP. It's set in case
the user forgets to use a real logging backend (syslog is the only other
supported logging backend right now).
