* Formatting follow-up
- Adds formatting commits to .git-blame-ignore-revs so that they don't
distract during Git blame
- Restores hard line breaks in Troubleshooting.md using `\` instead of
trailing spaces
- Changes formatting of some string literals and comments
- Fixes accidental Javadoc and comment issues introduced by manual changes
of formatting commit
- Fixes license header in $Gson$Types.java erroneously being a Javadoc
comment and being reformatted
- Slightly changes `JsonReader` `getPath` and `getPreviousPath` documentation
to help Javadoc detect first sentence as summary
* Remove `spotless:off` markers
* Add empty line before comment
* Check format for .github YAML files
* Document how `JsonAdapter` creates adapter instances & add tests
* Extend `JsonAdapter.nullSafe()` documentation
* Improve test for JsonAdapter factory returning null
Existing test `JsonAdapterNullSafeTest` had misleading comments; while it
did in the end detect if null had not been handled correctly, that only
worked because the field `JsonAdapterFactory.recursiveCall` is static and
one test method therefore affected the state of the other test method.
If the test methods were run separately in different test runs, they would
not have detected if null was handled correctly, because the factory would
not have returned null.
* Extend JsonAdapter nullSafe test
* Extend test
* Fix `Gson.getDelegateAdapter` not working properly for `JsonAdapter`
* Address review feedback and add comments regarding thread-safety
* Revert InstanceCreator instance validation
* Disallow `null` as `skipPast`
* Avoid `equals` usage in `getDelegateAdapter` & minor other changes
Previously `getDelegateAdapter` called `factories.contains(skipPast)`,
but unlike the other comparisons which check for reference equality,
that would have used the `equals` method.
This could lead to spurious "GSON cannot serialize ..." exceptions
if two factory instances compared equal, but the one provided as
`skipPast` had not been registered yet.
* Add code shrinking tools integration test
* Keep no-args constructor of classes usable with JsonAdapter
* Add library ProGuard rules for Gson
They are automatically applied for all users of Gson, see
https://developer.android.com/build/shrink-code#configuration-files
* Skip japicmp-maven-plugin for shrinker-test
* Add more tests for JsonAdapter, add tests for generic classes
* Extend default constructor test
* Add Troubleshooting Guide entry for TypeToken
The JsonSerializer/Deserializer adapters used to ignore this attribute
which result in inconsistent behaviour for annotated adapters.
Fixes#1553

Now the thrown exception carries this information:
java.lang.IllegalArgumentException: Invalid attempt to bind an instance of java.lang.Integer as a @JsonAdapter for com.google.gson.functional.JsonAdapterAnnotationOnClassesTest$D. @JsonAdapter value must be a TypeAdapter, TypeAdapterFactory, JsonSerializer or JsonDeserializer.
JsonAdapter is cached per the type of the JsonAdapter class.
Added a test to ensure JsonAdapter works on fields of parameterized types
Keep track of registered JsonAdapters and JsonAdapterFactorys in ThreadLocal.
