bazelbuild/bazel@6a8ddb7 changed the prefix for runfiles from the main
repo when Bzlmod is enabled. Because all uses of rlocation were
hardcoded to use "bazel_skylib", tests requiring runfiles stopped
working with Bzlmod enabled. This commit updates calls to rlocation to
instead use the TEST_WORKSPACE env var to get the repo name.
* Fix a number of misc issues to allow google usage of bazel-skylib
1. Missing copyright header
2. Shell test fixes to use TEST_TMPDIR to have write access to directories
3. diff_test fix to use TEST_SRCDIR
* added a comment as to why diff_test_tests is local
* ran buildifier
This new test rule compares two files and passes
if the files match.
On Linux/macOS/non-Windows, the test compares
files using 'diff'.
On Windows, the test compares files using
'fc.exe'. This utility is available on all Windows
versions I tried (Windows 2008 Server, Windows
2016 Datacenter Core).
