Services can be configured in `config/storage.yml` with a new key
`public: true | false` to indicate whether a service holds public
blobs or private blobs. Public services will always return a
permanent URL.

Deprecates `Blob#service_url` in favor of `Blob#url`.

Closes #37315.

Allow record to be optionally passed to blob finders to make sharding
easier.

Add configuration option to turn off drawing of Active Storage routes.

Especially, somehow `CHANGELOG.md` in actiontext and activestorage in
master branch had used 3 spaces indentation.

Use multipart uploads for files larger than 100 MB. Dynamically calculate part size based on total object size and maximum part count.

Need to new line to break line in the markdown.

Fix: #36065

The IamgeAnalyzer passes a image to ImageMagick without checking if the
image is supported by ImageMagick. This patch checks that image is
supported and if not logs an error and returns an empty hash instead of
raising an error. This is the same error handling we do when we
encounter a LoadError when mini_magick is not installed.

* Update RAILS_VERSION
* Bundle
* rake update_versions
* rake changelog:header

Accommodate case-insensitive filesystems and database collations.

If there is not a `csrf-token` meta tag in the document, the blob record
XHR was including an `X-CSRF-Token` header set to the string
"undefined." Instead of setting it to undefined, it should not be
included in the absence of a meta tag.

Generally followed the pattern for https://github.com/rails/rails/pull/32034

* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.

Applications can configure the route prefix prepended to the Active
Storage routes. By default this maintains the previous prefix
`/rails/active_storage` but supports custom prefixes.

Before this change the route for serving blobs is fixed to
`/rails/active_storage/blobs/:signed_id/*filename`. After this change
it's possible to configure the route to something like
`/files/blobs/:signed_id/*filename`.

The Azure gem uses `Azure::Core::Http::HTTPError` for everything:
checksum mismatch, missing object, network unavailable, and many more.
(https://www.rubydoc.info/github/yaxia/azure-storage-ruby/Azure/Core/Http/HTTPError).
Rescuing that class obscures all sorts of  configuration errors. We
should check the type of error in those rescue  blocks, and reraise when
needed.

This reverts commit b204d167, reversing
changes made to de6a200f.
