Get rid of global variables in dotest.py

This moves all the global variables into a separate module called
`configuration`.  This has a number of advantages:

1. Configuration data is centrally maintained so it's easy to get
   a high level overview of what configuration data the test suite
   makes use of.
2. The method of sharing configuration data among different parts
   of the test suite becomes standardized.  Previously we would
   put some things into the `lldb` module, some things into the
   `lldbtest_config` module, and some things would not get shared.
   Now everything is shared through one module and is available to
   the entire test suite.
3. It opens the door to moving some of the initialization code into
   the `configuration` module, simplifying the implementation of
   `dotest.py`.

There are a few stragglers that didn't get converted over to using
the `configuration` module in this patch, because it would have grown
the size of the patch unnecessarily.  This includes everything
currently in the `lldbtest_config` module, as well as the
`lldb.remote_platform` variable.  We can address these in the future.
