Looking for early feedback on these changes which Introduce multipool support to sqerl in a backward compatible way.

TODO:

  • make sure travis is passing
  • ensure both new and old configuration formats work.
  • determine if more tests are needed
  • revert local testing change
  • clean up history
  • clean up debug output

Correct test setup issues, and add a couple of mp tests.

- pool2 was apparently not a valid name for registering the
  pool process under - while the pool was created, it did not get
  registerd and so checkouts against it failed.
- fixed broken statement ordering in pgsql_create.sql

Some notes:

  • sqerl interface will continue to work as is. The main sqerl module now passes through most calls to sqerl_core, passing in a default pool named sqerl to ensure backwards compatibility.
  • sqerl_mp: this is the multipool interface. It's the same as the sqerl interface, but all exports require an additional initial argument of pool name (atom). It also passes through to sqerl_core.
  • A couple of specific multipool tests were added to verify that multipool is behaving when using a pool other than the default, but the basic multipool functionality is actually already covered when using the default interface - they hit the same paths.

Integrate the pool interface into main API.
ec58312 
This extends the main `sqerl` API by adding `_with` versions
of public entry points.  These functions each take an initial parameter
of context, which can be created with `sqerl:make_context(PoolName)`
where PoolName must be configured as a valid alternate pool.

The context form of this (instead of an atom for pool) keeps future
options to extend the API to include more features beyond alternate
pools
