* Remove redundant tests
* Add client connectionString test
Add test to ensure { connectionString } is respected as an argument to the client constructor
* Add test for connection string property
Also fixed some legacy require statements.
* Going red: using a config object creates two pools when missing some params
It should only create a pool in a consistent way, even if some params
are not provided in the first place.
* Delay the pool name generation to make it consistent between calls
* Don't fallback to empty object as config is already defined
The promise adapter I had implemented wasn't spec compliant: it didn't accept both `onSuccess` and `onFailure` in the call to `query#then`. This subtly broke yield & async/await because they both rely on `onError` being passed into `Promise#then`. The pool was also not returning the promise after a client was acquired, which broke awaiting on `pool.connect` - this is also fixed now.
* Initial work on removing internal pool
* Port backwards-compabible properties
* Cleanup test execution & makefile cruft
* Attempt to fix flakey error test
integration tests could now be started in binary mode
some tests are executed in text mode anyway, they are currently not
compatible with binary mode or prepared statements at all
(f.e. multiple statements in one query)
