a temporary Type.LabelVisitor instance per Attribute being visited. Instead, we can now create one temporary object per visitation. Getting rid of this dimension of scaling reduces the amount of garbage created.

Currently label-type attributes are detected in many places across the
codebase by simply reference-comparing against each of the label types.
This CL aims to generalize most of these cases, moving the encoding of
this logic into a single place (Type/BuildType itself). Not all of these
cases can be made general without further refactoring, and some perhaps
shouldn't be - serialization and Skylark rule context, for example, need
to do exotic things based on the type. But most sites can avoid having to
enumerate all the types they work with explicitly.
This causes LABEL_DICT_UNARY to start being treated like the other label
types, which means that CcToolchainSuiteRule and JavaRuntimeSuiteRule
need to include a set of allowed file types (none, in their case).
Skylark will continue treating it as a dictionary from String to Label
in its rule context, however, to avoid visible behavior changes.

See OutputFileConfiguredTargetTest for deep details.
Also more strongly enforce the expectation that all output files have generating rules.

Null generating rules shouldn't actually happen. That's its own bug that
needs its own attention. This change is just a workaround to prevent
NullPointerExceptions when the bug hits.

This makes is easier to understand and change which attributes are checked.
Also turn off checking for "data" and java_* "resources" attributes.

instead of passing and checking null in all helpers.
Demonstrates this pattern usage in a few select rules (e.g. AndroidBinary) where this was particularly egregious.
There are many places which can benefit from this pattern -- this change doesn't try to fix them all at once.

This implements most of a design proposal that splits constraint checking
into two pieces: *static* checks, which apply the standard constraint checking
done today, and *refined* checks, which selectively prune environments based
on select paths and check that not every environment gets pruned out.
As a result of this change, dependencies like:
java_library(
name = "lib",
restricted_to = [":A", ":B"],
deps = select({
":config_a": [":depA"],
":config_b": [":depB"],
}))
java_library(
name = "depA",
restricted_to = [":A"])
java_library(
name = "depB",
restricted_to = [":B"])
are allowed.
Specifically, even though neither "depA" nor "depB" supports [":A", ":B"], the combination of the two does. So the select as a whole supports all environments declared in lib, even though only one of those environments actually gets chosen for a given build.
Refinement makes lib "match" the chosen path. So for "config_a" builds, lib's environment set is "refined" down to [":A"], meaning [":B"]-restricted rules cannot depend on it. Likewise, for "config_b" builds, lib's environment set is "refined" down to [":B"], meaning [":A"]-restricted rules cannot depend on it. This guarantees that the restrictions imposed by the chosen select path propagate faithfully up the dependency chain.
See new documentation in ConstraintSemantics.java for more details.

The TransitiveInfoProvider already contains a label, use that instead.

This variable is no longer used because the docgen template directly calls
RuleDocumentationAttribte.getSynopsis() instead of using the SYNOPSIS variable,
and RuleDocumentationAttribute.getHtmlDocumentation() resolves the SYNOPSIS
variable to the empty string.

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.

- Label parsing can be simplified
- lib.syntax is only contains the code for Skylark and is reasonably independent from the problem domain of building things
This change is mostly only changes to imports declarations. The rest is reversing the dependency between :cmdline and :syntax and moving a tiny amount of code between Printer and FilesetEntry and the addition of SkylarkPrintableValue that I couldn't be bothered to separate out into its own change.

Before this change, constraints considered implicit deps anything from an attribute beginning with "$" or ":" (e.g. attributes that are completely hidden from BUILD files). Query agrees with this, but it also counts default values for *normal* attributes that aren't explicitly set in rules.
By syncing the two up, depot migrations can figure out which rules need to be constraint-annotated by simply running a bazel query --no_host_deps --no_implicit_deps.

1) Exclude host dependencies from constraint checking.
2) Check output files with the environment specs of their generating rules.
3) Provide a more generalized way to opt certain rule classes out of
constraint checking (this fixes accidental checking on config_setting
rules, which didn't really make sense).

environments)
the build is being done for.
In other words:
blaze build //foo:all --target_environment=//buildenv/target:gce
declares that this build targets GCE, so all top-level targets must also support GCE.
This essentially allows constraint enforcement to apply to top-level targets, too.
So users can protect against accidentally building targets in configurations they're
not meant to work with.
