Previously it's possible to have multiple copies of the "same" Template.
For example, if index.html.erb is found both the :en and :fr locale, it
will return a different Template object for each. The same can happen
with formats, variants, and handlers.
This commit de-duplicates templates, there will now only be one template
per file/virtual_path/locals tuple.
We need to consider virtual_path because both `render "index"`, and
`render "index.html"` can both find the same file but will have
different virtual_paths. IMO this is rare and should be
deprecated/removed, but it exists now so we need to consider it in order
to cache correctly.
This commit introduces a new UnboundTemplate class, which represents a
template with unknown locals. Template objects can be built from it by
using `#with_locals`. Currently, this is just a convenience around
caching templates, but I hope it's a helpful concept that could have
more utility in the future.

This is unnecessary now that we can just provide a file source

|

Now we can throw away the subclass and the generated methods will get
GC'd too

Every template that specifies a "virtual path" loses the template source
when the template gets compiled:
https://github.com/rails/rails/blob/eda0f574f129fcd5ad1fc58b55cb6d1db71ea95c/actionview/lib/action_view/template.rb#L275
The "refresh" method seems to think that the source code for a template
can be recovered if there is a virtual path:
https://github.com/rails/rails/blob/eda0f574f129fcd5ad1fc58b55cb6d1db71ea95c/actionview/lib/action_view/template.rb#L171-L188
Every call site that allocates a template object *and* provides a
"virtual path" reads the template contents from the filesystem:
https://github.com/rails/rails/blob/eda0f574f129fcd5ad1fc58b55cb6d1db71ea95c/actionview/lib/action_view/template/resolver.rb#L229-L231
Templates that are inline or literals don't provide a "virtual path":
https://github.com/rails/rails/blob/eda0f574f129fcd5ad1fc58b55cb6d1db71ea95c/actionview/lib/action_view/renderer/template_renderer.rb#L34
This commit introduces a `FileTemplate` type that subclasses `Template`.
The `FileTemplate` keeps a reference to the filename, and reads the
source from the filesystem. This effectively makes the template source
immutable.
Other classes depended on the source to be mutated while being compiled,
so this commit also introduces a temporary way to pass the mutated
source to the ERB (or whatever) compiler. See `LegacyTemplate`.
I think we should consider it an error to provide a virtual path on a
non file type template an non-file templates can't recover their source.
Here is an example:
https://github.com/rails/rails/blob/eda0f574f129fcd5ad1fc58b55cb6d1db71ea95c/actionview/lib/action_view/testing/resolvers.rb#L53
This provides a "virtual path" so the source code (a string literal) is
thrown away after compilation. Clearly we can't recover that string, so
I think this should be an error.

Per https://www.timeanddate.com/counters/firstnewyear.html, it's already
2017 in a lot of places, so we should bump the Rails license years to
2017.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

LookupContext is eagerly loaded, and FallbackFileSystemResolver is
referenced at the class level. Just require the resolver from the
eagerly loaded class rather than jumping through autoload hoops
