When adding a dependency on a module that has already had variants
created by a TransitionMutator, ignore any variation added by the
TransitionMutator to the current module if the TransitionMutator
didn't apply to the target module. This requires passing in the
list of variations requested by the AddVariationDependencies call
so that explicitly requested variations are not ignored.
This fixes TestAndroidTest_FixTestConfig when the override mutator
is converted to a TransitionMutator, as it can't add a dependency from
the "foo_test" module with an empty override variation to the
"foo" module that has no override variation.

TransitionMutator's top down mutator is suffixed with _deps, but
that name is often used by other mutators related to the
TransitionMutator, causing unexpected conflicts. Use _propagate
instead.

In order to do less cloning, refactor selects so that all the
soong-visibile structs are immutable to soong and can be reused.
Additionally, refactor how the inner linked list of selects is managed,
so that the append/prepend/replace logic is simpler.

The biggest issue here is that Configurable objects needed to be
cloned before appended to one another, otherwise some Configurables
that were used in defaults could be edited after being applied to one
module and apply a different value to another module.
Also fix an issue where a select without a defined appendWrapper
always evaluated to nil.
I plan to make a followup refactor cl to make these things clearer,
but start with the bugfix.

Sometimes modules add arch-variant properties in load hooks, to disable
modules by default on certain platforms for example. When changing the
property to a Configurable property, these load hooks would also need
to be changed in order to have a matching type for
ExtendMatchingProperties.
Since this can be kindof a pain to address everywhere, for now,
special case the extension functions to promote non-configurable
properties to configurable ones. We can remove this later when
everything switches to configurable properties.

Some soong code sets arch-variant properties in order to control a
module's default behavior. I'll make this continue to work, but long
term the arch-variant properties should be replaced with selects,
so expose an API for creating select statements in soong code.

Adding a dependency on a module that has already had a TransitionMutator
run on it may require adjusting the variation name based on the results
of IncomingTranstion. Store the variants that existed before the
TransitionMutator ran, find one that is a subset of the requested
variant, and call TranstionMutator.IncomingTransition to update the
value.

This adds support for selecting on multiple variables at once, so that
you can do AND/OR combindations of them. For example:
select((
arch(),
os(),
), {
("arm64", "linux"): ["libfoo64"],
(default, "linux"): ["libfoo"],
(default, "windows"): ["libfoowindows"],
(default, default): ["libbar"],
})
It also allows for select conditions to be boolean-typed. You can
write literal true and false without quotes to select on them. Currently
we don't have any boolean-typed variables though, so a fake one was
added for testing.

Part of the design of property structs is that they were easy to access.
In keeping with that spirit, use a shorter and easier to spell name
for the getter, and add GetDefault() so that you don't need to pass
the result of Get() to one of the
proptools.StringDefault/BoolDefault/etc functions.

If a property is a pointer to a bool/string, that property would be
replaced instead of appended to when calling ExtendProperties().
This is confusing behavior, and I don't want to give anyone any reason
to use a pointer to a configurable property, so add this relflection
tag to recreate the functionality.

Previously I was using an underscore to denote the default branch
because I was thinking that I would allow variable bindings in the
select branches, and 'default' could be mistaken for the name of a
variable. But I think it's better to just introduce alternate syntax,
like `default @ my_var: "foo" + my_var,` to do the variable bindings,
so that we can have a clearer name for the default case.

Currently, with the arch/os mutator, you can override a property
using the default value for just a few arch types, for example:
cc_defaults {
name: "my_defaults",
target: {
windows: {
enabled: true,
}
}
}
cc_binary {
name: "foo",
enabled: false,
defaults: ["my_defaults"],
}
You could make a select statment that acts like the above if it were
all in one module, but currently with select statements you can't make
a defaults module that can be generically applied to any other module
and have the same behavior as the above.
After this cl, the defaults module could look like:
cc_defaults {
name: "my_defaults",
enabled: select(variant("arch"), {
"windows": true,
_: unset,
}),
}
Which would have the same behavior. Unset may also be useful for
setting the property under some configurations, but wanting to leave
the implementation-specific default value in others.

* changes:
Store mutator in mutatorContext instead of name
Explicitly delete old logicModule entries from Context.moduleInfo
Keep logicModule for obsolete variants
Add Provider to transition contexts
Cache outgoing transitions
Use maps and slices packages
TransitionMutators will need access to the original *mutatorInfo,
store it in mutatorContext instead of the name, and update all
accesses to the name to go through the *mutatorInfo.

Creating variants has an optimization to reuse the logicModule of the
original variant as the logicModule of the first new variant. Using
the same logicModule meant that updating the Context.moduleInfo map
from logicModules to *moduleInfo would overwrite the old entry for
the original variant with the new entry for the first variant.
TransitionMutators will need to keep the original logicModule for
later use, which will require disabling the optimization that reuses
it. When the first variant is added to the map it no longer overwrites
the original variant. Excplicitly track the original logicModule and
remove it from the map if necessary.

When splitting a module into variants the original *moduleInfo was
left in place but with logicModule set to nil as a marker that the
variant was obsolete and any incoming dependencies needed to be resolved
onto one of the newly split variants. A change to allow TransitionMutator
IncomingTransition calls when adding dependencies later will require
keeping the obsolete *moduleInfo and logicModule around so that
IncomingTransition can be called on it. so use an explicit boolean
to mark the module as obsolete instead of clearing logicModule.

TransitionMutators were calling OutgoingTransition and IncomingTransition
twice, once to determine all the necessary variations for each module,
and then again when creating the variations to resolve dependencies.
Store the final variation needed for each dependency during the first

pass.
