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. llvm-svn: 254982
