* update status in README.md
* enable busybox tests
Adding `CONFIG_DESKTOP` and `CONFIG_LONG_OPTS` to busybox config.
These flags also enable other tests, but those utilities are not
included in `TEST_PROGS`. (eg. awk)
* fix whitespace and small issues
* fix Eq imp for FormatWriter on nightly + beta
* fix indention in multifilereader.rs
* fix intermittent errors in tests
Updates to individual integration tests
- use proposed conventional approach to beginning tests
- use new convenience functions for using fixtures
- use new names for TestScenario
Updates to integration test modules
- add proposed conventional module-level functions
Updates to test/common/util.rs
- rename TestSet, and its methods, for semantic clarity
- create convenience functions for use of fixtures
- delete convenience functions obsoleted by new conventions
The main motivation is to move toward running those tests for a specific
target, that is, if a test won't run on Windows, then we shouldn't build
it. This was previously the default behavior and prevented a successful
run on AppVeyor.
I borrowed this pattern from the tests in the Cargo project.
