I find it more ergonomic to add notes or a description about a test to a `doc` attribute, similar to other rules, vs a comment block above it or in the `impl` function docstring. Hopefully this can improve the readability of test rules.
This is a relatively simple addition to unittest that statically creates rules
that either explicitly fail or not depending on if the test case is valid during
LOADING phase of bazel. The test conditions are evaluated entirely in loading
phase, but if we want an actual test to fail rather than just `fail()` killing
the build, we can use this to assert state and report test failures.

In particular, this allows us to use a modern Stardoc release to fix generated md docs.
And we can remove internal_deps.bzl/internal_setup.bzl - it's unnecessary complexity
needed only for deprecated Federation setup.
* copy_file: Add parameter to allow symlinks
This change adds a new parameter `allow_symlinks` to `copy_file` that
allows the action to create a symlink instead of doing an expensive
copy if the execution platform (host) allows it.
Updates #248
* Update docs
* Refactor `is_executable` into attribute
* Fix typo
* s/_impl/_copy_file_impl/
This rule is an alternative for genrule(): it can
run a binary with the desired arguments,
environment, inputs, and outputs, as a single
build action, without shelling out to Bash.

native_binary() wraps a pre-built binary or script
in a *_binary rule interface. Rules like genrule
can tool-depend on it, and it can be executed with
"bazel run". This rule can also augment the binary
with runfiles.
native_test() is similar, but creates a testable
rule instead of a binary rule.
Fixes https://github.com/bazelbuild/bazel-skylib/issues/148
RELNOTES[NEW]: The new `native_binary()` and `native_test()` rules let you wrap a pre-built binary in a binary and test rule respectively.
The user can specify which line endings they want
write_file to use. This helps avoiding line ending
mismatches with diff_test.
Example: diff_test verifies that a rule generates
correct output by comparing it to a checked-in
"golden" file. Both files are text files, and the
user builds on Windows but the golden file was
written on Linux and git checkout preserved
original line endings.
Without explicitly specifying which line endings
to use, this diff_test would fail on an otherwise
good output.
With explicit line endings we don't need to check
in the golden file to git, we can just generate it
with "auto" line endings.
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).

Move maprule() to a private directory, to
discourage use of it. I (@laszlocsomor) am
planning breaking changes to it.
Also move private files (rule implementations) to
a subdirectory "rules/private/", to clean up the
"rules/" directory.
This PR adds two new rules: write_file and
write_xfile.
Both rules solve a common problem: to write a text
file with user-defined contents.
The problem is routinely solved using a genrule.
That however requires Bash, since genrules execute
Bash commands. Requiring Bash is a problem on
Windows.
The new rules do not require any shell.
The only difference between the rules is that
write_xfile creates an executable file while
write_file doesn't.
