This lets a parent choose a transition for its dep based
on the dep's rule class.
Implement (experimental) dynamic Android resource filtering
trimming with this.

fa97703c1edf ("allow skylark implicit output callbacks to use the rule
name") fixed a limitation of the skylark implicit outputs by adding a
special case for "name" to the implicit outputs code. Later,
015e5954157a ("Remove special handling of name attribute") fixed the
general problem of "name" being a special case in the attribute
map. Therefore, we can remove my original fix. We may also excise an
older special case in the implicit outputs templating code.

Currently ConfigSetting is treated specially; TransitiveTargetFunction
identifies it by name, then runs a special function on it. This change
makes ConfigSetting use a new options reference function in RuleClass,
which TransitiveTargetFunction will evaluate over the rule and use with
the options-to-fragments map to figure out which fragments are needed.
Although this is still a hack and not really a new feature on RuleClass,
this avoids a dependency on ConfigSettingRule from TransitiveTargetFunction,
which is necessary for ConfigSettingRule to be moved to rules/config.

BuildConfiguration currently depends directly on the name of a rule class
to see if it is config_setting. This creates a circular dependency between
ConfigSetting and BuildConfiguration.
As ConfigSetting is being moved to rules/config, this circular dependency
will no longer work. This replaces the name special case for a special
property of the rule class, which only config_setting should set.

This begins to allow for cases where a rule sets configuration
based on its attributes, such as where a rule attribute names
flags and their values - sort of a reverse select.
There are no such cases yet, but they're coming!

The new provider gathers actions generated by any Skylark-based RuleConfiguredTarget, so long as the rule definition has _skylark_test=True set. For the moment this flag is under the user's control, but the intention is that it will be set by a test runner.

Replaced late bound attributes with computed default attributes) with two bug fixes:
1. Unlike SkylarkComputedDefault, SkylarkComputedDefaultTemplate did not sort the names of its attribute dependencies. Consequently, lookup operations failed when callback functions in bzl files specified the names of their required attributes in a non-alphabetical order since the order of the key tuples was different (e.g. [1, 2] vs [2, 1]).
It would be less error prone to always sort the dependencies in createDependencyAssignmentTuple(), but this would impact performance.
2. SkylarkCallbackFunction ignores the legacy "cfg" parameter in callback functions. This special case should be deleted once all cfg parameters have been removed from the depot.

Motivation:
Compared to computed default attributes, late bound attributes are
evaluated in a later phase (analysis instead of loading phase). While
both mechanisms provide access to other attributes of a rule, only
late bound attributes additionally provide access to the build
configuration.
However, late bound attributes could be used to return new labels that
have not been loaded before. Since this happens in the analysis phase,
it can break one of Blaze's underlying principles, thus introducing a
serious correctness bug.
We decided to replace late bound attributes in Skylark with computed
default attributes since this moves the evaluation of values into the
loading phase, thus fixing this bug. Moreover, none of the existing
users of this mechanism required access to the build configuration,
which means that the user impact of this change is minimal.
Implementation details:
Unlike attributes of non-Skylark rules, however, Skylark computed
defaults need to be able to depend on more than two configurable
attributes since all attributes of Skylark rules are configurable by
default. This has two implications:
1. Unlike "normal" Skylark attributes, Skylark computed defaults need
to know about the existence of other attributes in order to declare a
dependency on them. This CL takes advantage of work previously done to
require parameter names to be the names of attributes used by the
computed default function.
2. Since Bazel computes the combinations of all possible attribute
values, a Skylark rule with a computed default that depends on a lot
of configurable attributes could crash Bazel. Consequently, this CL
also introduces an upper bound (64) for the number of valid
combinations.
Caveats:
1. Getting the depended-on attributes' names from function paramters is
mildly surprising.
Alternatives:
The best solution would be to keep SkylarkLateBound, but restrict it in
a way that it can only return already loaded labels. This is not
possible right now.

RuleClass is deserialized as part of a Skylark rule, the Environment is currently not present, but it is needed to detect changes to the rule.
Also precompute and store the Environment's hash code, and do a drive-by clean-up of a bunch of warnings in the Environment code.

bind() is assumed to be able to provide any provider. This is suboptimal, but beats the alternative of traversing the dependency graph to an arbitrary depth.
The reason for the removal of the iteration ability in TransitiveInfoCollection is that now aspects can be attached to BindConfiguredTarget, too, which is not a RuleConfiguredTarget. Whereas I could have implemented the iterator, it was used only in BindConfiguredTarget anyway, so there didn't seem to be much reason to.
Some work towards #952.

Sponsor's comment: note the abundance of new Label.resolveRepositoryRelative() calls. They are ugly, but it's only making existing ugliness explicit. Yes, we should fix it, especially in the implementation of configurable attributes.

Native rule classes can provide default values for rules after they're
deserialized, so there isn't a need to serialize those default values.
This doesn't apply yet to rules with Skylark-defined rule classes, due
to the non-serializablity of Skylark rule classes.

- 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.

.checksum() method that is computed from the checksum of the build options. Also remove Fragment.cacheKey() and Fragment.getName().
The reasoning is that within a single build, if two BuildConfigurations share the same BuildOptions, they must be the same because BuildConfiguration can only be a function of BuildOptions, specific targets (which stay the same during a build) and BlazeDirectories (which stay the same during the lifetime of a server). Between different builds if the configurations are recreated, they will always be considered different because Java reference equality (==) is used for comparing BuildConfigurations.
Also remove "Serializable" tags from configuration-related things.

The idea is that an android_sdk_repository rule would by default bind @external:android/sdk to itself, thus avoiding an unnecessary roundtrip through //tools/android:sdk . If we then also eventually bind that external label to something, we can avoid having the //tools/android:sdk rule altogether.

Move printing code from EvalUtils to Printer.
Rename functions in Printer:
printValue becomes str or print,
prettyPrintValue becomes repr or write,
formatString becomes format,
makeFormattable becomes strFormattable,
prettyPrintValues becomes listString.
write being self-sufficient is made the reference,
and print is the one that is a wrapper around write,
rather than the other way around, avoiding mutual recursion.

This makes the code cleaner because a lot of places never read the file and thus never needed a Path in the first place. I got to this change in a bit convoluted way:
- I wanted the default tools in Android rules to point to //external:
- I wanted to make sure that that doesn't cause an error is no Android rules are built, thus I had to add some binding for them in the default WORKSPACE file
- I wanted the Android rules not to depend on Bazel core with an eye towards eventually moving them to a separate jar / Skylark code
- The default WORKSPACE file is currently composed from files extracted by the Bazel launcher which would make the Android rules depend on a very core mechanism
- I couldn't simply pass in jdk.WORKSPACE as a String because Location, ParserInputSource and a bunch of other things needed a Path, which a simple string doesn't have.
Thus, this change.
