This allows us to have more complex test files where an action is taken, then
we test something, then another action is taken, etc.
Changes to test files are required so that URL is defined after all the
required settings are set.
Changes to the result files are either whitespace changes due to above logic
changes, or printing out a SQL Result header before each result. I figured it
was useful.
Changed line wrapping in awl is one major reason for etag changes.
With this commit, all tests in regression-suite, binding and carddav
pass for me, using the configuration outlined in README.regression_tests
