After @nathan-muir's PR #10053, we did not publish a new version of the
diff-sequence package, which would have contained DiffSequence.diffMaps.
I honestly have no idea why #10320 did not manifest before now, but
publishing these changes seems to fix it.
With the introduction of lazy compilation in Meteor 1.8, calling
inputFile.addJavaScript({
...
hash: inputFile.getSourceHash(),
...
}, function () {
return compiler.processFilesForTarget(inputFile);
});
becomes problematic, since inputFile.getSourceHash() is usually different
from compiler.processFilesForTarget(inputFile).hash, because the latter is
computed from the compiled code, whereas the former is computed from the
source code.
For example, when we use file.hash to cache imported module identifiers in
ImportScanner#_findImportedModuleIdentifiers, we really need to be using
the hash of the compiled code, since a single source module can be
compiled in different ways. If we cache based on the source hash, there's
a risk of reusing the scanned imports from the web.browser version for the
web.browser.legacy version, which can lead to all sorts of problems that
are only apparent in legacy browsers.
The quick fix is easy enough: BabelCompiler can simply stop including a
hash in the eager options to inputFile.addJavaScript. This fix can be
published as a minor update to the babel-compiler and ecmascript packages.
The remaining changes in this commit add another layer of defense against
this problem, by ignoring any hash options provided by compiler plugins,
in favor of simply computing the hash from the compiled data buffer.
These additional changes will become available in the next release of
Meteor (likely 1.8.1).

`autoupdate` and `reactive-dict` are using the `reload` package if it's available. To ensure that all packages are loaded in the correct order, these dependencies must be explicit.
- Return type of onMigrate callback should be an array.
- onMigrate callback can be invoked many times until all components
are ready to migrate.
- DDP negotiation failures should always migrate immediately.
