* 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).

Fixes some dictionaries to put things in the more common orders. Buildifer
used to default to doing this check and reformatting which is why the
//conditions:default got moved up in these in the first place.
All tests work with
`--incompatible_windows_native_test_wrapper`
except for the ones already broken on Windows
(//tests:analysis_test_e2e_test and
//tests:unittest_e2e_test).

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.

This PR adds two new rules: copy_file and
copy_xfile.
Both rules solve a common problem: to copy one
file to another location. 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 Bash on Windows (only
on other platforms).
The only difference between the rules is that
copy_xfile creates an executable file while
copy_file doesn't.

In this PR:
- In the _resolve_locations function: use the
Bash-less ctx.resolve_tools function to resolve
the runfiles manifests and inputs of tools,
instead of using ctx.resolve_command for
the same purpose.
- In the _custom_envmap function: no longer
resolve $(location) references when
creating the envvars from custom_env, because
those references were already resolved in
_resolve_locations.
The ctx.resolve_tools() method was added in this
PR: https://github.com/bazelbuild/bazel/pull/7139

- Retire the use of travis for testing.
- Update buildkite config:
- Enable buildifier testing (close to what was on travis, and is being improved.)
- Update the config to now test the latests release and the latest green, replacing
the "head" testing on travis.
* buildifier 0.22.0 includes files names in diffs.
* Simplify buildifier runs even more.
Since exit status are more consistently set and output is generally better,
don't bother being as fancy and just print a simple line as lead in incase
issues are found, and use the exit status to print directions on what to
do if something comes up.
Targets of this rule verify that targets can be analyzed successfully.
This is similar to build_test, except no actual action execution of
the underlying targets occur. analysis_test essentially verifies that
`bazel build [targets] --nobuild` passes.
* Add rules to the test_deps target.
Likely needed for anyone doing integration tests using skylib.
* Default public visibility and only tag things that are private.
maprule() is an improved version of
native.genrule(), with the following advantages:
- Maprule can process source files in parallel,
creating separate actions for each of them.
- Maprule does not require declaring all output
files. Instead you declare templates for the
output files yielded for each source. Therefore
N source files and M templates yield N*M
outputs.
- Maprule supports both Bash and cmd.exe syntax
for its commands via the specialized rules
bash_maprule and cmd_maprule.
- Maprule's cmd attribute does deliberately not
support $(location) expression nor Make
Variables, in order to avoid issues and
challenges with quoting. (In case of cmd.exe
passing empty arguments is impossible). These
paths can be passed as envvars instead.
- Maprule's add_env attribute does support
$(location) expressions (and some extra
placeholders) and is the idiomatic way to pass
execpaths of labels in "tools" or "srcs" (the
shared sources available for all actions) to the
command.

* fix typo
* Handing buildifier exit status better.
buildifier started reporting an error for lint issue, update the script
to not stop because of that.
In this commit:
- change unittest.bzl to declare a named output
file instead of relying on the deprecated [1]
default output name (ctx.outputs.executable).
- define a new toolchain_type and toolchain rules
for cmd.exe and for Bash (basically Windows and
non-Windows)
- register the new toolchains in workspace.bzl
- let unittest.make-created test rules require the
new toolchain_type
- write the test output script as a Windows batch
script or as a Shell script, depending on the
selected toolchain
This PR enables the Bazel team to break the Bash
dependency (for test execution) on Windows, and
can run Starlark unittests with the new,
Windows-native test wrapper (still under
development).
