Also adds some basic tests for these two. More tests are needed
but will have to wait for state to be finished.

We previously tried to send resize events only after the exec
session successfully started, which makes sense (we might drop an
event or two that came in before the exec session started
otherwise). However, the start function blocks, so waiting
actually means we send no resize events at all, which is
obviously worse than losing a few.. Sending resizes before attach
starts seems to work fine in my testing, so let's do that until we
get bug reports that it doesn't work.

This produces detailed information about the configuration of an
exec session in a format suitable for the new HTTP API.

As part of the rework of exec sessions, we need to address them
independently of containers. In the new API, we need to be able
to fetch them by their ID, regardless of what container they are
associated with. Unfortunately, our existing exec sessions are
tied to individual containers; there's no way to tell what
container a session belongs to and retrieve it without getting
every exec session for every container.
This adds a pointer to the container an exec session is
associated with to the database. The sessions themselves are
still stored in the container.
Exec-related APIs have been restructured to work with the new
database representation. The originally monolithic API has been
split into a number of smaller calls to allow more fine-grained
control of lifecycle. Support for legacy exec sessions has been
retained, but in a deprecated fashion; we should remove this in
a few releases.
